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.
"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).
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.
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
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.
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?
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.
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 !!!
+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.) ;)
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.
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 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 $70) slots into a pci-2 slot on your Motherboard and allows a series of SAS drives to interface with your PC. You will need the correct connection cables from the card to the drive interface as well, they are pretty cheap on eBay or Amazon. SAS drives are very reliable and ssd fast read and write - the card will let you add another 6g drive if you can fit it - cheapest fast storage you can get imo - I bought a redundant Dell Poweredge R710 server with 6 x 2 TB SAS drives very very cheap for a storage hub - my son uses it most for his games - my wife for streaming - when everyone is online it breezes through.
When I built my Pentium 133 PC many years ago I went with (parallel) SCSI because the throughput versus ATA really did make a difference. Also, the SCSI interface didn't care if you had hard drives, CD-ROM drives, toothpaste-cap fasteners, etc. on its bus as long as it was SCSI. Nowadays, the magnitude of performance gain just isn't there so I went with SATA III. IOW, I agree with what he said.
I build my own NAS machines. I get a HBA card and buy refurbished 4TB SAS (HGST) for ~$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.
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.
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.

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 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.
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.
SAS SCSI vs SATA ATA. SCSI Reads and Writes at the Same time 255 times, So this is SAS, where ATA SATA IDE EIDE all read or write only One Time at any given time. Think of Windows 7 8 even 10 on this SAS device, Read and Write would be much Faster on a Read and Write vs a Read or Write.
IDE is parallel while SAS and SATA are serial. IDE can only chain 2 drives while SAS could chain up to 65535 devices. Normally not a problem until you need ~ 100 drives per chassis. IDE and SAS are completely different systems. SAS and SCSI are far more similar.
IDE cables can be a bit ugly, but one of my friends bought IDE cables that had rainbow wires. It looked amazing!

Like he said, SAS is aimed at the enterprise market. You should be getting an SSD unless you are building a server.
@@HudsonGTV the dude reviewed a quantum computer. I don't think a server build is anything out of the question. Servers aren't far fetched
But to be honest he should just go straight to U.2

The odd thing is I found an hgst sas 4tb cheaper than a hgst sata 3tb hard drive I have no idea why it's cheaper.
next time GIGN vs SWAT plz!
SAS SCSI vs SATA ATA. SCSI Reads and Writes at the Same time 255 times, So this is SAS, where ATA SATA IDE EIDE all read or write only One Time at any given time. Think of Windows 7 8 even 10 on this SAS device, Read and Write would be much Faster on a Read and Write vs a Read or Write.
@thedster55 No one asked so why are you spouting in just to harass
@thedster55 Why don't you, then we can have real conversations not cancel culture
I still wish companies released a sata express drive like a few years back
The most important feature of SAS is daisy chaining of drives.
like the old ide bullshit...
IDE is parallel while SAS and SATA are serial. IDE can only chain 2 drives while SAS could chain up to 65535 devices. Normally not a problem until you need ~ 100 drives per chassis.
IDE and SAS are completely different systems. SAS and SCSI are far more similar.
hereiam2005 I said like not the same.
SCSI chain, terminated... or it doesn't work! LOL
Did NVME make SAS obsolete or is there still this consumer/enterprise usage difference that makes SAS still relevant?
Where did the video of the central office (brown racks on the left and right @3:14) come from?
