Ready for this speed freaks? Seagate just announced the world's first 2TB disk with full support for the
third generation SATA interface pushing data at 6Gbps -- double the rate of previous controllers. The 3.5-inch SATA 6Gbps Barracuda XT drive spins 4x 500GB platters at 7200RPM with a big 64MB cache to prevent bottlenecks. It promises a sustained transfer rate of just 140MBps (compared to 600MBps / 4.8Gbps possible), MTBF of 750,000 hours, and carries a five-year warranty. The disk hits retail this week for about $299 list. Then you'll just need to find SATA 6G controller / MoBo to make the most of your new purchase -- fortunately, SATA 6Gbps is backward compatible with SATA 1.5Gbps or 3Gbps rigs until then.

That picture makes me think that the disks are spinning in more than one plane. Heh, imagine that.
Totally spherical, dude.
Tubular, bra.
shows that platter technology isn't going away.
What does this have to do with platter technology? It's not like the interface is much of a bottleneck for traditional hard drives.
SSDs, however... now those are a good reason for 6Gbps SATA.
actually it just shows that first gen sata is fast enough for platters.
I hope platters NEVER go away. I love the fact that its a dime a GB, endless rewritability, and is just plain reliable. Yes, SSD is fast, but until you get me a SLC SSD that packs 2TB for under 2 benjamins, there will always be a need for spinning storage. Sorry, especially with this whole "digital distribution" thing coming around (which, again, I'm not a fan of, your rights fluctuate with any particular DRM server...), there will always be a need for mass amounts of storage that SSD's will not be able to fill for quite some time.
"We'll never need more than 640K of memory."
That's not a real quote.
What does memory have to do with hard disk capacity?
Yeah. Because HDDs can make us of all this bandwidth... NOT. Wake me up when there are SSDs with SATA 6Gbps.
Have a nice nap
SATA 6Gbps is pointless, except for SSDs.
Well you can connect 4 drives to one connection without saturating the thing, I understand SATA allows that actually, so you could get one eSATA cable out and connect 4 drives to a drive box and still get full speed, theoretically.
Correct me if I'm way off base.
Even if you're right its still barely scratching the bandwidth for 99% of users. SSDs are maxing out on 3.0Gbs so I can't wait for one to be made with the new spec for my as yet unbuilt computer!
@Wwhat You are correct, If SATA3.0 @ 6gb/s is capable of 600MB/s Throughput, and the drive mentioned here is capable of a sustained transfer rate of 140MB/s, a SATA3.0 port is capable of handling 4.29 drives (round it to 4).
You would of course need a port multiplier to reach 4 drives per port.
That does discount the burst rate of controller to cache which is normally higher, however, from a throughput level, thats the math.
However, If you had, say a SSD with a throughput of 200MB/s, then 3 drives would reach saturation point.
SATA3 "6Gbps" is just marketing now... but, it's a step towards the future. Soon, all hard drives will be using the SATA3 interface... which will replace older SATA1 and SATA2 interfaces.
A quick check on NewEgg shows only one hard drive with a SATA1 interface... and the other 70 drives are using SATA2. So, they've already stopped using the oldest interface.
In a few years, every drive will be SATA3... whether it needs it or not. They're just standardizing the interface. SATA3 will replace SATA2, in the same way SATA2 replaced SATA1. It's just the natural progression. It's nothing to freak out about.
nothing to freak out about, except the obvious socialist agenda these 'sata 3' hard drives are pushing. Its over, were dead.
/sarcasm.
No one is really freaking out.. Its just exciting to know about the new -everything- in computers.. Even if it's just another Intel processor at slightly less nm in production fab size.
The irony is, at 140MBps, that would only just saturate an SATA1 bus
It's got an MTBF of 85 years!? God damn!
Either that or one month. I'm guessing it's the former.
But it might not be that simple (http://db.usenix.org/events/fast07/tech/schroeder/schroeder_html/index.html).
I can't say I fully understand what MTBF means in practice.
A simple google search came up with this:
http://www.storagereview.com/guide2000/ref/hdd/perf/qual/specMTBF.html
Conclusion is, MTBF isn't an indicator of failure rate in a single drive, but it's not exactly a marketing gimmick either. It's safer to base the actual estimated longlevity of a single disk drive on the service life or the warranty of the drive than the MTBF.
I don't know what the industry standard is, but 5 years seems OK.
seagates 7200.11 series hard drives still gives me a bad image and the issue still
hasn't been resolved. will hold out and wait and see what the verdict is on seagates
engineering and firmware issues.
BS MTBF. They're most probably going to suck like their 7200.11 series and their drive-bricking firmware issues.
This is really neat, and very reasonable price too!
Well done Seagate, outdoing yourself once again.
Outdoing themselves once again?
They announced a 7,200 rpm 2TB drive back in FEBRUARY. That one was the Seagate Constellation ES 2TB 7,200 rpm drive. They STILL haven't delivered any, and you still can't buy any of these ANYWHERE.
I'll note that you can't buy these Barracuda XT 2TB 7,200 rpm drives anywhere yet either. At this point I wouldn't pay a lot of attention to Seagate press releases. When it shows up at newegg, then we can get excited.
Personally I think Seagate is falling behind the curve a bit. They were late to 2TB. They ARE late to 2TB 7,200 rpm (both WD with their Caviar Black and Hitachi have 7,200 rpm drives out and shipping already). They have no SSD strategy. The only Seagate drive I've got at the moment is a 7,200 rpm 500GB laptop drive, and I used to be a huge Seagate fan.
This picture reminds me of a sprint commercial. Where's Dan Hesse to tell me about freedom?
And just how much of a noticeable gain in speed are we talking about really? 1 second, 10 seconds, 20 seconds faster? Are we going to become the bottleneck or just more impatient? I think current hardware and software is plenty fast "for everyday users" - Speed freaks, yes you need this!!! - I think trying to squeeze every last speck of performance out of these things is so pointless. Solid state needs to become the norm not these bricks. But for now, these will do...

humble opinion ended....
My first thought was, "Why is Sprint selling hard drives?"
LMAO. Got the joke right away... Good one XD.
First thought: So Sprint is making hard disks now?
PS- If 2TB.....can haz 1TB 7200 laptop drive now?
Anyway to make one of these work on a computer with Sata 2 and keep the speeds?
Seems Sata 2 is fast enough for the drive...?
Will this work if i put this in my 15" macbook pro unibody?
cheers
There's a reason you use a Mac. That reason being this is a 3.5inch drive that you want to put in a laptop...
@ Daniel Roizman: You Dolt you can't fit this drive in a Macbook.
I'm going to give you the benefit of the doubt and hope you were making a joke referring to Apple disabling 3Gbps and limiting it to 1.5 in the macbooks.
That 'Show Press Release' button is new... Or is it just me?
Unless I'm looking through your eyes, you are not alone.
Why does it have to be Seagate....yucky
For a second there I thought Seagate was ripping off Imogen Heap's new album cover...
This could really elivate my Windows 7 performance score.... Woo Hoo!
What the hell is that word? Do you mean alleviate or something?
Oh wait, I see now... it's a misspelled elevate. My bad.
Is this hard drive only available on Sprint or something? The glowing yellow swirlies in the photos are throwing me off.
Seagate, makers of the 1TB drive that decided to lock up all my data after less than six months of use, rendering the drive useless? Um...no thanks.
Think I'll wait this one out. After all, Im already putting off laptop/ mobo purchase until USB 3.0 ships and the eSATA power thingy is dealt with in a standard way. Hope it wont be too long.
shhhh, you had me at TB
