USB 3.0 Performance: Two Solutions From Asus And Gigabyte
By

After noticing little to no performance difference in P55 native-controller performance with the Asus and Gigabyte boards, we decided to represent the chipset’s SATA and USB 2.0 controllers only once to simplify data charts. Asus and Gigabyte also use the same USB 3.0 controller, although different PCIe implementations require consideration of both. Gigabyte also offers eSATA, which is one of the technologies USB 3.0 is intended to replace, so the performance of its JMB362 eSATA controller is also compared.

Sequential Reads are limited by hard drive performance for all but the USB 2.0 interface in today’s test configuration. A faster drive in the Asus-supplied USB 3.0 kit would have likely improved this situation.

Sequential write tests may prove more revealing. Gigabyte’s implementation of the NEC USB 3.0 controller mimics that of the P55 chipset’s native SATA, while its first-generation PCIe-to-eSATA controller appears limited to around a 125 MB/s peak. Similarly, Asus’ USB 3.0 implementation falls to around 122 MB/s peak. Potential write-speed shortfalls of both third-party controllers are almost hidden by the performance of the 500GB Seagate 7200.12 hard drive.

    Great review. This waiting game sucks.

    This seems a bit dated, my two week old ASUS P6X58D Premium has Sata 6.0 and USB 3.0!
    Obviously waiting for a bit more mature drivers and more hardware...

    Can't wait for it all to be standard.

    BAH.... Im waiting for an X58 with USB.3.0 AND 16x 16x SLI. I would not want to sacrifice the other slot for a 8x config....

    Uh, d00d, 1366 CPU has 36 2.0 lanes, don't those X58 boards use the leftover four for USB3 and SATA6? I mean, c'mon, 16+16+4=36

    I've been waiting to see how USB 3 performs. However, if you may it's better to test the CPU utilization comparison between all connectors as well. Still, thanks for the great review. b^^d

    Honestly, with USB 3.0, I don't see any reason at all for eSATA anymore.
    I just want a 80GB Intel x18-m with a USB 3.0 port. Who the hell wants a slow 64GB flash drive?

    I wish we could agree on a stanard already. I like USB, so let's just scrap IDE, SATA, eSATA, PCI (not PCIe), analog audio cables completely already. Well, that or miniDisplayPort.

    Thanks for explaining how USB 3.0 fits into the grand scheme of things.

    Looks like I'll stick to using esata for a while longer. Not too thrilled with the early implimentations.

    Cant you build 2 computers with the same motherboards, and then run a network through usb 3.0. Run raid in both with ssd, and then fully test bandwidth? That way you are maxing out the spec?

    I'm With Thackstonns on this one. Would have been nice to have done a more in depth look and used raided SSD's. See if you can max out the interface with enough of them. Is that possible?

    ? ? ?

    ASUS P6X58D-Premium has 16x16x8x with USB.3.0 & SATA.6G/s, I have had mine for two weeks and loving it.
    It does tripple LSI or Crossfire.

    Running it with I7-920 and 6gb of Patriot 2000 mhz cl8

    On the Back Panel there is 4 USB2.0 2 USB3.0 (backward compatable) Inside 2 USB2.0 hdr, 6 SATA-3.0 and 2-SATA-6.0 as well as a E-SATA hdr

    With having an e-SATA external hard drive, I see no quick need to upgrade to USB3.0, as their is little performance difference. I'm waiting more for the performance increase overall with the SATA-3.0 hard drives, at which point I'll upgrade my motherboard.

    That would be great if the hardware to connect the two had been available. It's certainly something to look for, now that you've suggested it!

    It's possible if you send two SSD's in a 3.5" internal bay adapter that has a built-in RAID controller. Of course, this could be problematic still since the USB 3.0 adapter provides only SATA 3.0 Gb/s (we've also been told that it's limitted to 180MB/s on current firmware). But other than the lack of hardware...

    Although its good to see the hardware in the wild, I don't yet see any reason to buy something for USB 3.0 and SATA 6GB/s.

    Yes there is some future proofing, but as I think it was mentioned at the beginning of the article, it will be years before we see a significant number of USB 3.0 and SATA 6GB/s devices on the market, and maybe even longer before we see storage with the ability to use all that bandwidth.

    Certainly it will take aeons for traditional hdds to utilize all that speed, but ssd's might be able to do that in a few years, right?

    SSD's could probably do that now if they applied 24-way parallelism to the internal controller and the fastest available chips.

    Sounds good, but on the "Throughput, Streaming, And Interface Performance" page you have a mix up of letters "Regarding write speeds, Gigabyte’s eSATA controller looks a little better while Asus’ USB 3.0 implementation looks a little worse in IOMeter. USB 2.0 performance remains relatively pathetic, so eSATA and UBS 3.0 will both give you a substantial performance boost."

    Crap posted before I was done, but anyway the mistake is that you stated it as "UBS 3.0" and not USB 3.0. Tiny error.
