AMD and Seagate demo 6Gbps Serial ATA

Today AMD and Seagate are teaming up to demonstrate the next-generation Serial ATA specification. Dubbed SATA 6Gbps, the new spec will offer twice the disk-to-host bandwidth of the existing 3Gbps Serial ATA standard. Although the fastest Serial ATA hard drives on the market have a rough time maintaining transfer rates higher than about 110MB/s, they can typically push smaller burst transfers from their caches at over 250MB/s. Those caches are growing, with the latest desktop models packing 32MB memory chips. And let’s not forget solid-state drives like Intel’s X25-E Extreme, which has no problem sustaining over 200MB/s for reads and writes.

Despite its fatter pipe, SATA 6Gbps will use the same connectors as the existing Serial ATA standard. The spec includes new goodness beyond a higher throughput peak, too, but AMD and Seagate are only talking data rates for now.

While today’s technology demonstration is not a product launch, we can tell you that the demo drive is based on Seagate’s current Barracuda 7200.12. It’s running on a next-gen AMD chipset with a brand new storage controller of the company’s own design. That setup, according to Seagate, has hit a peak data rate of 589.09MB/s. There’s no word yet on when the SB750’s much-needed successor will arrive, but Seagate expects to announce products compatible with SATA 6Gbps before the year is out.

    Ok, so they’re ONLY going to double the bandwidth to 600MB/s? PCI-e v2.0 has 500MB/s per lane! A x4 slot is 2000MB/s!

    Solid state devices will soon outstrip this mediocre increase in speed. A Fusion-IO SSD already outstrips the 300MB/s speed of SATA, which is why partly why Fusion-IO had to put it on the PCI-E Bus.

      This is not “mediocre”, they doubled it. It’s officially more now than what most people will ever need. I call that an affordable and good answer.

      Even OCZ is coming to the market with a device like the Fusion-io. They have a 4 disk SSD drive with a built in RAID controller that sits in a 4X PCIe slot. They claim to push 500MB/sec read and write speeds.

    seems about the right time with SSD speeds being what they are. By the time this actually comes out in a buyable form I wouldn’t be surprised to see SSD’s pushing past 3gbps.

    So the guys who can’t make a working HDD team up with the guys who can’t make a working SATA controller for their chipset in order to demonstrate the latest SATA spec. This should end well…

      Yea ok, why don’t you go show Seagate how to make hard drives. Considering the fact they made the first perpendicular recording hard drives as well as the first 1 TB hard drives, I think they know what they are doing. AMDs sata controllers work just fine, just turn off the AHCI option in the bios.

        • TravelMug

        Believe it or not I tried. They didn’t listen to me, so when the latest issues started to appear all I could tell them was:

        “Sorry guys, but I tried to help you in the past and all you did was hurt my feelings. With this one, you’re on your own…”

        I know, I know. Harsh, but fair.

    Bout time AMD had a SATA implementation worth getting excited about. Let’s see if they fix AHCI. Damn well better. I’m taking this too personally, I know.

      • Hattig

      Am I right in guessing that AMD’s current SATA controllers are third party components that have been integrated into their southbridge, and in the next southbridge (SB850? 810? 800?) they’ll be replacing that with an in-house design?

      Good to move from licensing third party IP that could have dodgy drivers, and replacing that with your own IP that could have your own dodgy drivers instead :p

        • flip-mode
        • 11 years ago

        The current controller is either ATI’s or third party. I dunno. Perhaps the AMD/ATI team will together produce something really dynamite. The fact that they are actually /[

        The AMD SATA controllers derive from Silicon Image technology up to SB600 and likely beyond.

    THIS JUST IN:

    Not to be out-done by AMD, Intel has released a 6.001GBps SATA standard, which just so happens to be electrically incompatable with the new spec by AMD.

      How about Fugu? Using it would similarly tempt fate and the results would run the gamut from proper function, to malfunction needing warranty replacement, to death.

      Earth to everybody.

      All HDDs are mechanical devices. They are all guaranteed to fail. It is just a matter of time.

      Every HDD manufacturer in the past and present has made a bad patch of HDDs that died prematurely. It is Seagate’s turn now. Just avoid the models that are problematic.

            They’re not. They’re not hard disk drives, because they don’t have any sort of a disk, let alone a hard one. They’re “drives” to be sure, but solid state ones, therefore begging for the “SSD” moniker /[

    Will SATA at 6Gbps see a significant reduction in latency vs. SATA at 3Gbps?
