- Deep dive into the engineering and physics of the soon to be generally released Seagate HAMR (Heat Assisted Magnetic Storage) drives, starting with the Mozaic 3+ 30Tb CMR and 32Tb SMR HDDs.
But its not just Seagate that are working on this, Western Digital and Toshiba are also investing in EAMR (HAMR and MAMR) for their disks, but how reliable is the technology going to be? Lets go deep into the challenges, the solutions and how it works at the atomic level, its fascinating!

Looking at the way hard drives work, they seem nothing short of an engineering miracle
Love the speed of ssd-s, but hard drives are really like magic hiw they work.
Not really anyone who has ever mowed a lawn can see how you can adjust the alignment of a material (Grass) to generate patterns. The principle of how a hard drive works is rather easy to understand. The head of the drive is the lawnmower, the current passing through it is the blades of the mower, and the platter is the ground and the coating, the grass.
@@IdgaradLyracant The concept is simple, but using a macro scale component to read and write bits at nano scale is not. It's like saying you can technically use a needle to poke a CD to create a windows installation disc.
@@cucumberworksand now on top of that we are heating that precise spot to make it easier with even smaller needle
It's not just hard drives, it's computing in general. It's insane computers work at all. Literally every part of a computer is starting to push the boundaries of physics.
its amazing that hdds work at all
Sad that SSDs are getting more expensive tho. Would have loved to just switch over to SSDs for my stuff
It's amazing that high capacity SSDs cost a shitload of money these days...
@@Alpine_flo92002 What do you mean? They are around $60-70/TB, slightly more than last year, but still much cheaper than anytime before ~2022.
@@Alpine_flo92002 No they aren't. HDDs and SSDs are both getting cheaper and SSDs are actually getting cheaper faster than hard drives
@@thoughtynessMaybe in the long run, but the ssd manufacturers like Samsung and Micron are reducing the supply to get better margins.
just purchased a exos 18TB, I am amazed by how the technology keeps improving
I just got a 14 exos and kinda wish I got a bigger one. Great drive though.
@@_-Karl-_ yes. Ha. Its my backup for the 3 5tb drives I have. I know the math doesn't add up but it works. I know though I'm going to surpass the 12.7 allocated and probably will get 2 20s when prices go down so I have 3 full copies. As of right now I feel it would be extremely hard to fill up a 20tb with "usefull" data.
Its crazy to think my 2tb drive 13 years ago was the cost of my 14tb. My first mp3 player was like 512mb. Now I can't fit all my music on a 512gb sd card. Lol
But it's improving beyond logic. As HDD become bigger without improving performance they are starting to become a bad quality tape. If you build a RAID with say, 8 of these drives and have a failure, even if the drive sustains 100% peek performance and it's only 60% full it will take close to 19 hours to rebuild. Long enough that the possibility of a second drive failure during a rebuild is real. Clearly, it will take maybe 2 to 4 times more time (because of random iops) so you get the picture.
@@jaimeduncan6167 how much data are we talking? You make it seem impossible to have redundancy. Get 3 24 tb drives (for most people) and just use a drive cloning device. That way your drives are not spinning for thousands of hours. Why would you want 8 drives running in case 2 fail at the same time. Now if we are talking 100tb+ sure. But op said 18tb. I have a 14tb and 3 5tb drives. Just purchased a 2nd 14. Its super simple to back your stuff up. Take me 24 hours to do a 14tb backup on a drive and my drives maybe have 1000 hours on them. Everything I utilize is transferred to an ssd before. The thought of a NAS is cool but your 10 year old laptop can do it with an external drive flawlessly.
If I'm going to run plex ill buy the 2 8tb ssds I need. Because when data backup is a priority I think people tend to forget how much it sucks to lose data. The data you use all the time use an ssd when its storage us a hdd.
Incredible! 50TB drives would be nice 😮
Quite the deep dive, kind of amazing to know HD's work at these kinds of scales.
They wanna reach 120 tb storage in 2030. The random Access speeds gonna be bad, bad damn.
You really got me with the message notification sound at 11:34 ;-)
Thank you for watching all the video. Or maybe sleeping through the video and then getting woken up at the end. 😊
there will be one big "most replayed" bump at that spot eventually
UNbelievable - Laser light to surface plasmons on tiny gold discs, heating 30nm pegs, in turn heating the media with nanosecond pulse widths. 🤯
I remember the ancestor of those drives, the Hammer drive, which got high density on an optical medium using a similar method, it was magnetising the media, but reading was done instead via the polarisation change of the surface depending on the magnetism, using an optical pickup with a polarised light source instead.
This was really cool tech. Quite a few comments here that people remember it. Minidisk was also built on the same principles I believe.
@@sometechguy If you were dealing with DTP in the 1990's you were almost obligated to have at least one, along with Zip drives, as most of your artwork for packaging and products would need to be sent on physical media, and making revisions was long. Also you had them being the biggest early adopters of CDR and CRW drives, even if they were only capable of reading and writing at 1x speed.
Thank you for explaining how they solve the challenge.
Fascinating, seems even more magic than the working principles of flash memories.
Agreed, we're having mass produced mechanical devices reliably work on the atomic scale at dizzying speeds. That pure engineering sorcery.
With flash storage, the magic seems more constrained to the manufacturing side.
Very nicely explained.
Hamr's out finally! I'm so excited
I have 16TB Seagate EXOS HDDs on my NAS and they are kind of loud. I hope this new tech can lower the noise too while increasing the reliability and capacity at the same time.
Those are Enterprise drives, meant to run in some server room, where noise is absolutely not relevant.
Great video. Very interesting to catch up. I thought my current PC had huge storage at 8Tb on 2 discs. Amazing physics, as well. Look forward to their release - they may already be available - I’ll go check.
Matt Lee
Thank you, and I thought it was fascinating also. There reports from Jan that they would be Q1 launch, and the website is updated, though no data sheets I could find yet. So I hope it’s close.
20TB's from seagate were available back in 2021, but they weren't really economical to buy until 2023-24
I see other people noticed the similarity to the old magneto-optical discs! It’s such an amazingly cool piece of technology.
Yes, this seems to build on that technology. 👍
We think SSDs are the future when hard disk technologies are still rapidly evolving. Looks like hard disks won’t die anytime soon
considering tape drives are still evolving and have insane capacities it's not really about if the tech is going away, but consider that we now have 64tb nvme drives that are both faster and larger capacity than hdd now, meaning going forward they will likely be the future of non archival storage , especially as price comes down. of course new disc media is coming out as well so we might see the Resurrection of bluray
So far, so good. But hard drives are bound to go obsolete in about 10 years. Far more room for development in SSD tech.
@@nomnommonsterr considering a hard drive can survive a house fire and an SSD can't i'll stick with HDDs for my storage needs
@@manitoba-op4jx don't drop your hard drives because they have higher failure over SSD if you do.
Imagine the time it takes for chkdsk command to scan an entire drive. Partition management would have to scale up as well maybe by grouping partitions into a single virtual drive but error checking will be by partition.
Fascinating. This is not my field at all. But I can't comprehend how the nfts, being necessarily larger to intercept the lasers, then smaller at the pegs to precisely deliver the heat, all fit together given their larger size than the data layer points at the pegs.
The transducer as a whole is larger, the specific sizes are not published and I guess they could change depending on the application, but as you say, it would need to be at least the size of the laser light wave as it leaves the wave guide. Then the peg at the bottom would want to be the target size for the specific domain its targeting. And again, this size could change depending on the targeted data density. But very small, in the 10-30nm range I would expect. But the diagram isn't measured to scale, because the actual measurements do not appear to be published (unsurprisingly)
And this is going to be a simplified explanation, as I am sure the detail is important from a fabrication standpoint and its also likely to be intellectual property which isn't in the public domain.
As for the disc and the peg, I don't know if they are fabricated as a single item or joined, but in my research I did find that they had some challenges with the peg recessing into the disc at high temperature which had to be solved by densifying the metal, which is a fabrication process where the material is compressed during manufacture to reduce this happening during operation. And this (at least from what I found) addressed this issue.
Man vs physics: the road to victory
Many years ago I had 60 GB disk space in my first PC and I thought that was a lot. Now I have 30 TB.
Isn’t the exponential nature of technology amazing.
When you break it down, it's pretty much magic!
Its 50+ years of iteration, but still, its pretty amazing tech.
Finally a drive big enough to hold my homework folder
you should call your channel THETechGuy. i feel that the head swing arm is unnecessary take 4 head assemblies at 90 deg, these are static with the laser and near field transducers on each, they can then carve all read writes between the 4 of them of keep 2 each dedicated to reads and writes, also these structure can perform continuous error correction of bit rots
I wonder if at some point they'll need to increase the physical size of drives. Like 2" tall drives with 20 platters, or 5" diameter that sacrifices speed and for capacity.
There used to be a form factor that would potentially work, 1.6” high drives. Though I’m sure around 80% of all drives produced today would be used in data centres and in disk shelves or severs which use 1” high drives, so the various drive manufacturers are more or less stuck with making 1” tall drives because the cost to make 1.6” or 2” drives would nowhere near even close to worth it considering how they wouldn’t sell anywhere near as well as the 1” tall standard drives due to a lack of compatible hardware.
They did that with the BIGFOOTxl Drives. I have one in storage.
This is the problem, everything is standardized on the 1" form factor. But there is a roadmap to over 100Tb, so who knows what comes after that. The SATA / SAS interface is probably the real issue. It would take so long to get a 100Tb onto a disk.
@@sometechguy Folks will just upgrade to SAS at 12Gbps.
@@OreoBambino they would need to redesign factories, maybe part of the equation. cheaper to push out " a bit too small form factor" x 1000 vs just right XXL x 100
OMG, I've been wrong all this time! I always said NFTs are worthless, but it looks like there's at least one NFT out there that isn't! :)
😛
Crazy
What I want to know is what kind of error detection and correction technology is being built into these very high density hard disks. As a consumer, my biggest concern is the safety, reliability, and longevity of the data on the disk.
Presumably if you use but then at some point archive a hard drive this hammer will mean that the drive should maintain their archived data much longer than non-hammer drives?
I don’t know what the stats are for retention times, and I have not seen a statement about it. But I think it follows that if the data is far harder to write to at normal temp, then bitrot should actually be reduced. But maybe that would need more data on recoverable / unrecoverable errors found on these disks.
I wonder if it will get utilised in an external USB 3 hard drive? That would be an interesting product.
No reason it couldn't, but you'd be looking at a premium price tag. Better to grab one on sale one day and slap it in an enclosure. If you're talking about a small form factor, then maybe, maybe not. It depends if they bother to manufacture 2.5" drives with this technology, or deem it not worth the development cost.
holy, this is miracle engeneering. But it does make me wonder, what will be the uses of this? More space per HDD is ofcourse awesome, less space used and that saves money, but if it fails, the drawbacks could be way more..
In summary: magic.
Pretty much what it seems like these days...
Am I the only person that wishes they would work on cost rather than working on size. HDD cost to value has been stagnant for years now. 10TB drives should have fallen to the magic $99 price point by now.
It is slowly coming down. I remember back in 2018 getting a 1tb for around $100. Now I can get a 3tb for the same price. But higher is more pricey. It would be pretty cool to rock a $100 10tb or bigger.
Cost is getting down, you're just looking at it from wrong side.
Look at it as:
Base cost (casing, electronics, ect) + cost per plate and rw head.
The denser the plate - cheaper it becomes (per TB). Also you're ommiting simple fact: base materials and electronics is not getting cheaper, so how can you expect HDD getting cheaper, while it requires electronics 😂
PS.
Im ommiting other important costs, like R&D, more expensive electronics, ect.
All the things you mentioned except R&D gonna cost them max 10 bucks
as a committed data hoarder I am prepared to max out a credit card to buy these drives
Storage increase is nice, but in practical usage and backup of backups I will stick with smaller drives that don’t take 3 days to fill at 150MB/s
Newer drives can easily do 250 Mbytes/s. The only interesting measure is price per TB. This will heavily favor bigger drives. Also don’t forget price per slot.
No sense in trying to run backups on an entire drive when incremental methods are available. Of course, a full reconstruction would take some time, but hopefully is a rare event.
If only you could kick off automated, manageable, daily backups.
Nah, it would never work. Do yearly backups or whatever nonsense you're complaining about.
the main issue : HDD are getting so slow to fill because size increase way faster than speed, HAMR won't save HDD
Does heat assisted writing also mean that write cycles to certain cell/area is finite?
No, it should not be the case, at least not with reasonable usage numbers. The idea is that the material is not degraded and that it just changes the coercivity (ability to write with the head) of the write domain for a very brief period. Seagate say they wrote 2 PB to a platter surface, so thats a lot of writes.
Hard drives already have a finite lifespan and duty cycle.
People bang on (and on and on and on) about SSD lifespan under the supposition that hard drives last forever under similar circumstances (i.e. writing terabytes per hour, for some reason.) They do not.
But no, HAMR will not give a hard drive any shorter of a lifespan than current PMR drives.
@@sometechguyThat number is good to know, but it's interesting to compare that to common advice to keep drives spinning because thermal cycling is the biggest contributor to long term failure rates.
I wonder what a write thermal cycle looks like at nanoscopic scale, what thermal gradients it induces between one track and the next, and whether there are particular material stresses they had to compensate for.
can you do a video on RAID SATA SSD's ?
I do plan to do some deep dives into SSDs, how they work and and how they compared with mechanic storage for speed, capacity, endurance and price point. So keep an eye for that.
in the late 90's early 00's i heard of a tech for storage using some sort of crystals?? - we were interested due to limitations of 'G' on a/c and this tech did not suffer from that, and was (on paper and according to manu) was much faster than anything else - the scenario the manu put forward was going to a vid shop and buying a movie with it taking seconds to download onto your storage media (in the old days of video shops)
have you heard of anything like this??
This might have been the '5D Optical Storage'? I don't know what happened to this since then, but not heard about this recently.
@@sometechguy - we were going out on a US trip and were going to look into it, but events took over - the concept being, that putting a DVD type solution on any a/c is massively expensive and not what you get for commerical - issue being with any disc based solution is moving parts and 'G' under load, hence why so expensive - this new solution had no moving parts, more akin to an SSD (but not an SSD)
Awesome and scary at the same time.
You can never have enough space, But imagine rebuilding a storage pool in your home NAS.
They are looking at 100TB drives in 2030 and beyond, I would hate to think how long a rebuild would take, Instead of days maybe weeks. o.O
Yea you're right. A failed 1tb drive sucks and takes forever to transfer data on/off. Doing it for a 30tb or even that future 100tb would suck so bad! I would hate having to just let my pc sit there forever working on moving data around. It sucks enough as is lol
hmmm, so I'm guessing the Secure-Erase will not be quick any more. Because it will have to write every bit and not do a wider frequency zap.
It may depend how they implement it on the drive models. Secure Erase can be done by overwrite the entire drive, but can also be done by encrypting all data on the drive with a key generated and stored on the drive, and then just discarding the key. This then makes all the data unrecoverable.
I always claimed that hard drives are just work of magic. It is like threading a needle riding in a car on a bumpy road, while spinning, in a hurricane, during an earthquake, flawlessly trillions of times. Now even more so.
I heard of HAMR and EAMR and patterned media for like 15 years probably, but finally things a real and in production. It is all pretty cool, but flash is catching up. Flash already can store more (easily 50TB in 2.5in drive) and way way faster, but economics still favor magnetic media if you do not need highest performance, but just cheap capacity. Gap is closing tho. If they say 100TB for disks in 2030s, but flash will be in that range in the next 2 years and in smaller form factor. So all matter of price really.
As antiquated as they sound, they phenomenally intricate devices, despite just getting stuck in a drive cage. And though NAND is catching, it’s very expensive per Tb at that scale, the endurance remains an issue also. And the problem of performance vs capacity is real. The highest density cells are the slowest and the least enduring. So I think that breakthrough needs to happen to really consign ‘spinning rust’ to the history books.😀
Is HAMR as slow as SMR for sustained writes? As opposed to constant speeds with traditional CMR drives.
Because the problem with SMR drives is they are basically unusable in professional environments where you need redundancy, where you may be copying large amounts of data, or replacing drives, generating even more sustained writes. Therefore in pro environments, you're very likely to do sustained writes, especially on bigger drives, that may be like 10 times slower with SMR than with CMR, which increases the risk of a second drive failing while the array is rebuilding a degraded RAID for example.
Currently no indication that the HAMR technology itself would be slower. There is actually a 30TB CMR and a 32TB SMR drive listed, but I would assume its a host managed SMR drive, rather than device managed and these would behave a bit differently.
HAMR doesn't work in the same was as SMR, where SMR results in data being partially overwritten and needing to be rewritten back to the media, and this is why in simplified form that sequential writes get slow on SMR once the cache is filled. HAMR writes in a similar was as CMR/PMR, its just that the media is heated in the process and the data is more densely packed.
Theoretically, the denser the data, the higher the throughput could be because more data is contained in a track and can be read in a drive revolution. But until datasheets are released and the drives can be tested for long term sustained read/writes, we won't know for sure what the throughput is. if I had to guess, for the CMR 30Tb drive, its going to be ~280MB/s, in line with the higher capacity Exos drives.
@@sometechguy Thanks a lot for the very precise answer and clarification! Can't wait to see that available!
32TB HDDs coming out soon, thats kinda crazy, i remember when 4TB HDDs were the highest lol.
That's nothing, I remember the first 1 GB drives appearing in 1996. And also the 1 TB intro in 2007.
I remember when 40MB disks were huge! I think I still have an 80GB somewhere.
Is this now something to use in a NAS or Raid
I would want to check the pricing, and though Seagate have it on the site, I don't think pricing is finalised yet. But if the pricing was right, I would try it out for sure.
I wonder if this heat required to write data effectively will increase the HDDs power consumption significantly. 🤔
This very concern is addressed at 10:42
@@nextbreeze7974 Thanks! That's awesome if power draw won't be an issue.
Finally a good explanation of what the fuck an NFT is
This NFT? Or the one with the monkeys 🙈 🙄
This is going to probably use more electricity, meaning probably need a bigger PSU, and with electricity prices, will these drive catch on?
We will see, but the power requirements for the laser itself should be fairly low as the area heated is so small.
There would be one needed per platter surface, and only used for writes. I am waiting for the official data sheets, which I didn’t see yet. And it would be good to test this against a comparable 10 platter unit like the X20 20Tb or X24 24Tb.
Back in my day, they just made larger hard drives.
Seagate says up to 50TB at least in a few years. HDD is life :)
Data hoarding 😎
@@sometechguy r/ 😁👍
protect your hdd from cosmic rays people
Seagate is like: "We present you HAMR technology!"
Sony, which released MiniDisc in 1992: "Yeah-yeah, we heard about it somewhere... Aah! WE developed it! "^_^
P.S. Maybe someone else developed it even earlier...
This is starting to become complicated. How long does it take to rebuild a 30TB HDD that is at 60% utilization? It will take forever exposing the RAID array to a second or third failure (catastrophe) during that time. We all know HDD performs pretty bad on random IOPs, but even if we assume the drive will be rebuilt at max sequential speed ( 270MB/s) it will take 19 hours.
They should bring the ”Bigfoot” (5.25”) back!
Would be great, if any case can fit them in any more. I think those are in the rear view mirror now. 🙂
There was a time when there were 8" disks, and actually 14" before that. Back when they went in huge cabinets and capacities were in the Megabytes. How things changed.
@@sometechguy , well, pretty much every case has a place for OPTICAL drive. Which is 5.25". Which is same that Bigfoots used.
It seems that ssds wont take over in NAS systems afterall
SSDs are great for high performance storage. Buy for NAS storage, I think it will be spinning magnetic storage for a while yet. 🙂
Incorrect @ 2:20. This is not how data encoding works. It is a function of transitions, not states. Familiarize yourself with the concept of run length limited encoding (RLL) and its derivatives.
It's an interesting comment about encoding, but this is just a visualization of how data is magnetically stored on the disk to highlight the size of the magnetic domains and I am not trying to go into other tangential topics here. But I do appreciate the comment, and thank you for watching and taking the time to post it.
I don't think that more TB for proportionately more money is what people want, otherwise we would just buy more drives. It's not like most users have to build a data centre for all their storage.
More TB for a little more money is what they need to aim for.
For some, density is the key thing to save cost in infra and data centre space, for others it’s price per TB. Initially, I think this would be mostly targeted at hyperscale customers, and less at consumer. Hence why they are being tested now for some years at these big data storage customers.
Price per TB continues to fall however, and this will only help. For less density driven use cases, it’s possible to fit more data per platter, which reduces platters/heads etc and reduces component cost. So this can only be a good thing from a price per capacity standpoint also.
You're describing small people with small needs as though they're the only ones who exist.
"Just double the drives"... and the cabling... and the power supply... and the HBA ports... and the difficulty of maintaining them... etc. etc.
"Why buy a van when we could use two sedans???"
@@tim3172 What I am saying is that buyers large and small want more storage per dollar. Not double the storage per drive for double the price.
@@sometechguy Sadly price per TB drops have been far slower in later years when going after historical prices. I'm willing to pay a premium for a bigger HDD vs 2 smaller onces but this has its limit. It's already annoying in the GPU space that you nearly have to pay x% more for x% more performance, even though a new GPU gen should offer a far greater generational price per performance leap.
At the moment I own 2x 20TB, 2x18TB and multiple 12, 8 and 4TB drives and would love 30TB+ drives so I don't have to split the data over multiple HDDs (+ redundancy). Also I'm running out of space again already and would like to buy drives far above 20TB next. Of cause besides size and price there is also the factor reliablility, where Seagate is still stigmatised. I own mainly Toshiba and WD drives but never had a failed drive since getting my first PC in 94 and this includes a handful or Seagate ones too. My wife once dropped one of my external WD drives while it was running and I had some data loss but it still works to this day (like 7 years later).
I would love to get an Ultrium 8+ LTO drive if they weren't far to expensive for private use. So HDDs are the only way for me to backup my data.
With my needs I'm most likely part of a minority that is of no concern to these companies. Thing is, is enterprice interest in HDDs really so high if they can use SSDs for their speed and access times and LTOs for backups? I should ask my colleagues from our high performance computing centre if they still use HDDs to any meaningful degree in their 40+ PB setup.
But what are they going to do about the speed of these drives? Sure I would love for there to be bigger and bigger drives, but if that means I have to wait 4/5 days or a week for my Parity rebuild to finish I can't use them. Will these drives use dual activator or similar?
If your array is small enough that you can use smaller drives, then use smaller drives for the daily use and bigger drives for backups. (RAID is not a backup.)
We are going to need a new sata spec. 30+tb of data is going to take forever at current speeds.
Yes, SATA in its current form was standardized in 2009. And modern drives are getting to the point where they can saturate that link. So seems to be time.
@@sometechguy sas even got 2 more versions since then. Its a shame they just gave up on sata.
When I say modern drives, probably the only one that is really close to link saturation is the dual actuator Exos MACH.2 SATA drive at around 545MB/s max. But if they implement dual actuator more commonly, it could be a problem.
Will be interesting what the Mozaic drive does for data rates in the future with denser platters, it looks like the initial model will still only do around 275Mbps, a little slower than some of the recent Exos.
@@sometechguy i mean ssds on sata hit the limit easily. So that alone should have been reason for a spec update.
And i would guess throughput would increase as a natural consequence of the increased density of hamr drives especially if they combine with multi actuator.
@@acolyte8564 yes, your totally right.
Seagate didn’t honour my warranty…..and their drives don’t last as long….yet, they want my good money. They better be 20% cheaper than WD to compensate in order for me to feel like I got value.
Where did you buy your disk? On eBay, there are some third party sellers who are not on the drive manufactures approved supplier list, and buying there might cause warranty issues. They also do not make this clear at all. Or was this from an approved seller?
Rather than go for increased capacity, it would be more helpful to go for durability and reliabilty. Personally I am sick of losing my data and constantly worrying about losing my data. Further the whole world is in the same boat. Whilst we have never been more productive, we are losing most of what we create.
Do you keep backups? That's how you get piece of mind.
And anyway any storage medium that lasts long enough is going to run into lack of hardware support to read it. See: tape (audiocassette/vhs) floppy drives, zip drives, compact discs/DVDs, etc.
If only you could make a copy of your data and put it somewhere else.
You should write that down. It's a billion-dollar idea, right there.
Nothing is perfectly reliable. I'd bet on a proven HDD for long-term storage over any SSD that can fail catastrophically at any point with no warning. HDDs usually give signs before failing. Also, I'd stick to WD for reliability, but you can check out this channel's reliability comparisons between the brands.
@@chatboss000 I have a LOT of drives, all duplicated, but you can still get caught.
But the point is we have books and scrolls thousands of years old and can still read them. Drives barely make it to your child's Kindergarten graduation.
Sound like some hybrid tech between Sony Mini Disk and HDD
I'm not sure what "Mini Disk" is.
Sony created a format called MniDisc; which sounds similar.

Oh boy! This means more metadata collection of my farts and more Netflix! Well, at least I can store more ray-traced brown individual shooting simulators locally. I hope a flood doesn't cause prices to remain fixed this time. I wonder how long it'll take to fill up on my copper landline my ISP hasn't touched since the 80's despite universal fibre being funded several times.
Soooooo, magic….all you had to say was magic. I would have understood that a lot more. 😂
Friends don't let friends use Seagate....
I see a lot of commentaries - if fails bla bla bla .
Everything in this life at some point fails , dealt with it , move on , stop moaning
So it's like MO disks from nineties but smaller
I think in some ways similar, the write area is heated to its curie point and a magentic write heads sets the polarity.
And in some ways different, reads are done in a traditional way as hard drives, and I think the magneto-optical drives used polarized light.
Those drives were pretty slow I think for writes. But there are a lot of parallels. So this is a good call out.
Hah, I just bought a 18TB Exos in your video! Lookin' forward to new storage solutions, though, I'm not even sure what I would ever do with that much capacity.
You would probably have said the same about the 18Tb drive not so long ago. 😁
@@sometechguy 18TB is the most I've ever had, all my other drives are 6-8 and those are filled up, though admittedly, with a bunch of junk. I really need to clean my files... or just offload them all to a 30+ drive =)
