"SAS stands for Serial Attached SCSI". Alright, what's SCSI? "SCSI stands for Small Computer System Interface". Somehow I feel like a video on drive connectors is needed if not already done; like, I remember when ribbon cables (like IDE/PATA) were all the rage when 40GB drives and 128MB RAM was considered a lot (actual stats from our first Windows computer).
+kolby4078 Knowing Techquickie (is there really?), they'd probably cover the most common ones only (unless they were all common, then they'd have to generalise).
I built a (4) 146G 15K drive SAS RAID 0 array back in the day. Sustained read/write speeds were comparable to a single modern fast SSD (around 500MBps), but with 20x the power consumption and LOTS of heat. We really have it good with our SSD's.
In 1992 I worked on 1TB Sun SCSI array that was in a deployable vehicle. It took up 8 full size racks just for the drives and required a 15KW generator to run the system and the air conditioning. State of the art at the time and the system was over a million dollars. Now I can buy a drive more capable for 100 bucks and put it in my pocket.
Something I noticed is no mention of T10 DIF/DIX or T10 PI/DIF, which helps protect against silent data corruption (SDC). I'm not sure if _all_ SAS drives are capable, though I now you cannot get the aforementioned features on a SATA drive. DIF = Data Integrity Field DIX = Data Integrity eXtension PI = Protection Information
Cheers for the video, have passed this onto the rest of our team so they can maybe explain a bit better to our customers as to why the expanded storage for their servers costs so much more than the extra hard drive they put into their home machine last week.
Wait... SATA is also full duplex. Also worth noting is that SAS and SATA share the exact same PHY layer. They differ somewhat in the transport layer, with SATA using a master/slave system with either a single slave or up to 15 via a port multiplier, and SAS using a mesh network system allowing for many drives and host computers to all be connected via switches, and at the higher layer, SATA drives using the simpler ATA command set but SAS drives using the more complex SCSI command set.
OMG, talk about a throwback, the BROWN cabinets is a Nortel DMS switch at a telco. It looks like a Sprint CO (Wireline). Then I noted this video is 8 years old. I worked in one of those CO's for 10 years. Man, the memories.
Putting aside performance, the reason you would like to use SAS drives is for the ""build quality"", they're made with very high quality materials and constructed more rigid with extra vibration and shock protection; even including ECC unlike the common use hard drives. Also SAS controllers are better designed and coded.
Good thing tough is, that you can connect up to 4 SATA drives on a single SAS connector with a breakout cable, as the SAS is capable of carying 4 SATA signals over over one connector.
You don't need SAS for that. You only need SATA backplane, case and motherboard specifically designed for such installation (for example USB NAS storage devices have those). What SAS has use for home use, is being able to have storage cluster and use external SAS cable to store all your files to that-...or use it as your boot drive and not having to have any storage devices installed on your PC xD.
@@Kilzu1 Ah yeah, that works as well. I just meant that if you use a SAS PCIe card (like a LSI2008 for example which can be had cheap on ebay) you can use two SAS to Sata breakout cables and attach 4 SATA (or SAS) drives to one mini SAS port. Didn't expect to get an answer after 7 years but yeah, my storage server now for example uses 3 LSI2008-8i cards that are attached to a backplane which has 24 Sata drive bays. of course I could use an expander but at the time of looking those LSI2008 cards were cheaper than SAS expanders. And the server has PCIe lanes to spare so why not?
I have a home file-server which I'm upgrading soon. 6 Gb/s SAS (with a sata breakout splitter) for RAID, and just because the motherboard in the system doesn't have enough sata ports, or RAID capabilities built in. Its pretty expensive, but hopefully it'll be worth it for my large transfer / video render things.
+SimplyPhysics LOL, CoD fanboy over here. Do you seriously believe that because he hasn't heard of a game series you like, he should end his own LIFE?!? Also, I think he means he hasn't heard of CoD: Modern Warfare 4, since that game doesn't currently exist (and hopefully never will.) ;)
Most of the stuff around internet is usually scattered even if you try to learn about a single thing. But thnx to you for explaining everything in a nutshell !!!
When I built my Pentium 133 PC many years ago I went with (parallel) SCSI because the throughput versus ATA really did make a difference. Also, the SCSI interface didn't care if you had hard drives, CD-ROM drives, toothpaste-cap fasteners, etc. on its bus as long as it was SCSI. Nowadays, the magnitude of performance gain just isn't there so I went with SATA III. IOW, I agree with what he said.
I build my own NAS machines. I get a HBA card and buy refurbished 4TB SAS (HGST) for ~$AU50 each. At this price point, I can afford if one or two doesn't last very long, I just replace it. With a SAS9200-8i card you can connect 8 drives. That is a 32TB storage for under $AU500.
A 15k rpm drive would be 2x as fast. Cheaper to set up 2x 7200rpm in RAID 0 though. Mine run at about 400 MB/s. Ive seen 2x 12gb drives running at 534MB/s. They used to make 10k rpm SATA drives called VelociRaptor.
Sounds to me like SAS could benefit anyone who feels constrained by consumer IO subsystems. Would it be more cost effective or aid in any other way to have SAS storage and 16GB of RAM or SATA and 128GB of RAM for high end media production?
I learned that SAS exists this week because I jumped on a $17 2TB drive on eBay, then spent 20 minutes trying to figure out why it wasn't fitting in my enclosure.
I just had the same thing happen to me.,, I got it to fit in the drive bay, though... barely. Thought I got a great deal on a 6TB drive, and then when it arrives... whoops - the connectors don't connect. I didn't even know there was anything other than SATA still OUT there, so didn't bother to check the connection info. Now I'm stuck with a drive I have no idea how to use... and no money to use to expand the space in my home media PC.
@@HudsonGTV Can you please explain what an HBA card is? Would it allow the SAS drive to be used like a regular drive? I got what I thought was a great deal on a 6TB drive for my home media PC, only to have it not fit. And everything I've looked up says the cheap adapter cables people are selling don't work because the SATA interface still can't read the drive. I'm so confused right now I have a headache.
@@Dove01s The HBA card (Amazon $70) slots into a pci-2 slot on your Motherboard and allows a series of SAS drives to interface with your PC. You will need the correct connection cables from the card to the drive interface as well, they are pretty cheap on eBay or Amazon. SAS drives are very reliable and ssd fast read and write - the card will let you add another 6g drive if you can fit it - cheapest fast storage you can get imo - I bought a redundant Dell Poweredge R710 server with 6 x 2 TB SAS drives very very cheap for a storage hub - my son uses it most for his games - my wife for streaming - when everyone is online it breezes through.
Wow dude, you're a pro. This description took no time. You clearly know what you're talking about. Every other description was full of fluff of people who had no idea what they were talking about.
I came back to this video for referencing information about the sas interface for a server build out for my home network, I am going to be deploying several servers, all using the sas interface for my storage. I am in fact making a home database.
Linus - with the current technology we are at. What is the optimal 20 to 40 gaming PC controlled by one shop and the most cost effective way with software needed to run a computer shop like this? is it still individual PC,'s or is it one centralized storage and farmed hds? security and networking speeds considered. GO wild. but im more after a practical cost effective setup.
Linus, can you explain Windows version/edition? what's N, rtm, oem, LTSB, VL, features on demand, TH2, insider fast ring/slow ring, branch R1, threshold builds, Redstone build, Public Builds, ESD, SVF. Please!
I heard that qualcomm quick charge 3.0 promises lower charging temps and hence longer overall life of your battery, wanted to know if it is worth buying a 3.0 charger. Also would it work on a Samsung galaxy s5 or do I need a new phone to make use of it.
I have planned a long time to build a "Home database server or something like that" in the future, when i have space for it. I would like to have a central place with redundancy for files i need to store, with a easier way to backup than messing with my personal computer. And if i need it it could be possible have some small virtual servers running AD DS, or LAMP in the future.
Looking to upgrade my homeserver, currently running 13 drives using an onboard controller and an external sata controller, Would it be optimal for me to use a SAS controller with those 1 to 4 splitter cables? and what controller is to recomend?
Hey linus was wondering, im still rocking a asus p6t deluxe and i7 920 as i still havent really had any reason to upgrade yetw apart from of course .. loads times. One thing thats bugged me is my SSD running in SataII. I THINK my board is SAS III. So the question.... Will i gain any benefit running my SataIII SSD in the SAS-Bus(12gbps) over the SataII(3gbps) ? Thanks
Were thinking of maybe buying a Western Digital - Ultrastar He10 HUH721008AL5200 with SAS 12Gb/s. What SAS to SATA adaptor would you recommend to use temporary, until I get a more modern motherboard, or expensive PCI-e card with SAS input? Have btw motherboard PRIME Z370-P with the 6 Gb/s SATA inputs.
Hello. I recently found a 10 years old Server. I tried to boot up from a USB, and it worked. I was trying to install Ubuntu Server, but the Hard Drives weren't showing up. Do SAS hdds need to be set up manually?
Great Video! By the way I have a question, I have a hp notebook model (17-bs025cl) and I can't really know if my optical drive bay supports SATA (and which SATA version if it supports it) because I'm planning on installing a SSD in the optical drive bay using a caddy I've tried lots of third party software and they say it's an ATAPI.. I can't seem to find an answer on the web on what is this ATAPI or whether my device controller is SATA or IDE please if you can help me in anyway.
Hey linus? How about updating info on SAS? I started to dabble in it for data storage for my office nas; holy shit. Mega different connectors; forward or rearward data connectors and a lot more. One was when everything was hooked up and power applied. It just sat there kinda like that hot Friday night date after one too many and she was waiting for her prince to take her to levels of ecstasy never experienced before. I after two hours reading find out I have to disable the 3v at pin 3 deliberately preventing spin up. I scared the crap out of my co workers when they told me they were hearing wolverine snarls and snaps coming from behind the door of my IT cave.
I have a rack server server in my basement to store and stream my stuff and I still went with SATA drives over SAS. SATA is cheaper and SAS is just overkill for home servers.
I ordered a SAS drive by mistake, my mobo only supports sata, can I use it with a sata to SAS adapter? only looking to use for storage, no raid set up. cant return the drive... any advice?
great explanation, good that i put 24 sas drives in it for home Database Storageworks instead of sata :-) HP p2000, ssd's would be more expensive but i am not sure if this worth it ? do you know that maybe ? Thanks.
never thought about it before now, the ppl gaming, game recording, live streaming at the same time,(and maybe converting and uploading to youtube at the same time) all processes at the same time, would this sas hdd improve anything at all?
can you buy a sas 2tb drive and replace circuit board for a sata pcb board both drives are identical but off by 1 digit in model number or are these fine tuned at the factory making swapping pcb boards not a viable solution
Hey Linus, can you explain why there are different mobo, with seemingly the same name that are different prices. I understand there are tiers, but what do higher tiers really offer?
3:48 So here's the thing though...Mechanical drives can only have the head in one place at a time. So the ability to send and receive at the same time shouldn't matter much...at all. The increased rotation speeds of up to 15,000 RPM help with this, sure, but even so, mechanical drives are just so limited. I would bet money, and a lot of it, that large data servers would do JUST as well, performance wise, with high end SATA drives as they do with their 15,000 RPM SAS drives. They are probably wasting money buying SAS drives....however, a lot of SAS drives are probably more reliable and that's what REALLY matters, I would think.
A SATA SSD can send or receive up to 6Gbps (750MB/s - overhead) and a SAS SSD can send and receive 22.5Gbps both ways (5600MB/s - overhead). That's a really massive improvement, SAS being 7,5x faster than SATA. The SCSI language is more advanced than ATA, which is important for error-recovery, for instance. That's important for things like RAID. Since they use breakout cables, it's easier to use SAS for DAS cabinets. The cables can be up to ten meters long, which is important in data centers. SAS supports multipath IO, SATA does not. In short, there's a reason why you don't see 30TB 2.5" SATA SSDs, but only SAS. As a personal user, you don't care at all about SAS drives, because they rarely hit the second-hand market for data protection reasons, but you really love your second-hand SAS controller.
I'd like to see a vid on *_DisplayPort_* and it's miniature Apple counterpart, *_Mini DisplayPort | DisplayPort Mini_* as well as its replacement, *_Intel Thunderbolt_*
Thank you for this very informative video. I have never heard of SAS before, as I was on newegg.com looking up HDD's and saw SAS, couldn't figure out online, but duckduckgo provided this video.
Say I'm making a videogame, and plan on doing alpha tests on my own small office hardware. would a SAS environment be better for large scale multiplayer and world size? vs say a raid 1 or 5 array of 7200rpm data drives with a 64Gb ssd for cache.

Yes…. 2x 4T SAS HDDs for my Serverbuild 😐 and now i cant use them. 😂 might have to bus a used SAS controller card
SAS controllers are always good for splitting out more SATA ports. It's what I do for my FreeNAS box.
Just make sure it's an HBA for FreeNAS, not a raid card.
@@JensHove good call

One time I've wondered what was that weird connector and in this video I finally know why is it for.
Something I noticed is no mention of T10 DIF/DIX or T10 PI/DIF, which helps protect against silent data corruption (SDC). I'm not sure if _all_ SAS drives are capable, though I now you cannot get the aforementioned features on a SATA drive.

Wait... SATA is also full duplex. Also worth noting is that SAS and SATA share the exact same PHY layer. They differ somewhat in the transport layer, with SATA using a master/slave system with either a single slave or up to 15 via a port multiplier, and SAS using a mesh network system allowing for many drives and host computers to all be connected via switches, and at the higher layer, SATA drives using the simpler ATA command set but SAS drives using the more complex SCSI command set.

I miss him on your channel
Great Video! By the way I have a question, I have a hp notebook model (17-bs025cl) and I can't really know if my optical drive bay supports SATA (and which SATA version if it supports it) because I'm planning on installing a SSD in the optical drive bay using a caddy
I've tried lots of third party software and they say it's an ATAPI.. I can't seem to find an answer on the web on what is this ATAPI or whether my device controller is SATA or IDE please if you can help me in anyway.
B-roll at 3:13 is either one of my companies labs or a customer site. Erie how everything is in the exact same places, and dressed the same.
Hey linus?
How about updating info on SAS?
I started to dabble in it for data storage for my office nas; holy shit. Mega different connectors; forward or rearward data connectors and a lot more.
One was when everything was hooked up and power applied. It just sat there kinda like that hot Friday night date after one too many and she was waiting for her prince to take her to levels of ecstasy never experienced before.
I after two hours reading find out I have to disable the 3v at pin 3 deliberately preventing spin up. I scared the crap out of my co workers when they told me they were hearing wolverine snarls and snaps coming from behind the door of my IT cave.
Thumbs up for the Grandma data-center photo. I lost it.
happy new year from holland!
If SAS is optimized for multi-user connection, then it would be appropriate for using it to host VM images, yes?
Is SAS good for video editing? Why are you referring only to people with gaming pcs?

Time to re-do this video
I have a rack server server in my basement to store and stream my stuff and I still went with SATA drives over SAS.
SATA is cheaper and SAS is just overkill for home servers.
This video was made just in time! Thanks!
thanks for your video. does SATA driver can accept SAS interface ?
You should make one on Fiber channel too just for the fun of it. I know this was in the SAS market area, but I think it may be fading due to SAS.
I like the progress by SAS, it's surely not the end, thanks and kind regards
It’s sad that SATA won’t be updated at more. Otherwise, SAS will be lower priced.
I ordered a SAS drive by mistake, my mobo only supports sata, can I use it with a sata to SAS adapter? only looking to use for storage, no raid set up. cant return the drive... any advice?
great explanation, good that i put 24 sas drives in it for home Database Storageworks instead of sata :-) HP p2000, ssd's would be more expensive but i am not sure if this worth it ? do you know that maybe ? Thanks.
happy new year guys
Just out of curiosity, why haven't we got an update to SATA standard yet? It seems to me like it is needed.
never thought about it before now, the ppl gaming, game recording, live streaming at the same time,(and maybe converting and uploading to youtube at the same time) all processes at the same time, would this sas hdd improve anything at all?
PCIe vs SAS vs SATA benchmarks and real world performance comparison on LTT main channel incoming? Just do it!
I have a 6x450 GB Raid 5 with SAS HDDs. Dataspeeds about 680 MB/s unbuffered and 1,4 GB/s buffered.
I still have to find a video where someone compared a 15k to a ssd
What happened to the compression at 3:25? Linus tuns into like 4 pixels. Even watching at 240p there is a huge difference.
*3:45
i bought 4 used 250gb 15k rpm SAS drives for £10 each and a £3 SAS to SATA adapter.. 1 TB SAS storage for £43 not bad ;)
can you buy a sas 2tb drive and replace circuit board for a sata pcb board both drives are identical but off by 1 digit in model number or are these fine tuned at the factory making swapping pcb boards not a viable solution
I just came across Linus' video about SATA again just recently. Woah.
Hey Linus, can you explain why there are different mobo, with seemingly the same name that are different prices. I understand there are tiers, but what do higher tiers really offer?
Would it increase performance when using multiple VMs accessing the drive at once?
Yes. Full duplex will help the VMs perform better. But now you have nvme M.2 drives that are much better.
Happy new year Linus and team

3:48 So here's the thing though...Mechanical drives can only have the head in one place at a time. So the ability to send and receive at the same time shouldn't matter much...at all. The increased rotation speeds of up to 15,000 RPM help with this, sure, but even so, mechanical drives are just so limited. I would bet money, and a lot of it, that large data servers would do JUST as well, performance wise, with high end SATA drives as they do with their 15,000 RPM SAS drives. They are probably wasting money buying SAS drives....however, a lot of SAS drives are probably more reliable and that's what REALLY matters, I would think.
A SATA SSD can send or receive up to 6Gbps (750MB/s - overhead) and a SAS SSD can send and receive 22.5Gbps both ways (5600MB/s - overhead). That's a really massive improvement, SAS being 7,5x faster than SATA. The SCSI language is more advanced than ATA, which is important for error-recovery, for instance. That's important for things like RAID. Since they use breakout cables, it's easier to use SAS for DAS cabinets. The cables can be up to ten meters long, which is important in data centers. SAS supports multipath IO, SATA does not. In short, there's a reason why you don't see 30TB 2.5" SATA SSDs, but only SAS. As a personal user, you don't care at all about SAS drives, because they rarely hit the second-hand market for data protection reasons, but you really love your second-hand SAS controller.
I'd like to see a vid on *_DisplayPort_* and it's miniature Apple counterpart, *_Mini DisplayPort | DisplayPort Mini_* as well as its replacement, *_Intel Thunderbolt_*
Thanks for providing information that is really helpful.
A Squarespace ad. Linus already saw his future.
Really informative video !! Now i know i can plug SATA HDD into SAS controller.
Thank you for this very informative video. I have never heard of SAS before, as I was on newegg.com looking up HDD's and saw SAS, couldn't figure out online, but duckduckgo provided this video.
i have trouble with my dell precision T7500 no SSD will work on the sas controller, and there are only 3 sata ports, and one is needed for hard disk
Can i use SATA 3.5 & 2.5 SSD (Desktop hard drive) in my dell poweredge 2950?
yes
Say I'm making a videogame, and plan on doing alpha tests on my own small office hardware. would a SAS environment be better for large scale multiplayer and world size? vs say a raid 1 or 5 array of 7200rpm data drives with a 64Gb ssd for cache.
