AS-SSD Incompressible Sequential Performance

The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers, while other drives continue to work at roughly the same speed as with compressible data.

Incompressible Sequential Read Performance—AS-SSD

Incompressible sequential read testing is fairly boring as nearly all SSD capable of SATA 6Gb/s perform the same, and the Performance Pro is no exception.

Incompressible Sequential Write Performance—AS-SSD

Incompressible sequential write speed is another story, though. Here the Performance Pro is dominating our charts. It's actually surprising how big the difference is. We are looking at over 60MB/s (17.2%) difference between Plextor M3 and the Performance Pro.

    Anand is waiting for the final version before publishing any data. Apparently there are a few things that OCZ promised will be featured in the final version, but I'm not sure what.

    I plan on running drives in Raid 0. Trim doesn't do anything there so its important how a drive deals with a no trim situation.

    I've been running first gen vertex drives in raid 0 since they were released and since installing the firmware on them that enabled garbage collection they have been fine and they are routinely at 90% capacity.

    What firmwares are you running on these drives?

    Thanks!

    Corsair has not posted any firmware updates so in this case it's the stock firmware (1.00 I think). I'm not 100% sure what firmwares the other drives are running but you may be able to find that info in the review of a certain SSD. However, some drives were tested quite a while ago so they may not be running the latest firmware. We try to update our charts if there are significant gains from a newer FW, though.

    I would like to see my Mushkin Enhanced Chronos Deluxe 240GB reviewed & compared please!!
  • biodtl - Tuesday, May 15, 2012 - link

    I second that notion! The Deluxe is a real performer and could put up some competition here.

    Just sent an email to Mushkin :-)

    Hi,

    You wrote

    "Neither Plextor or Corsair manufactures the drives they sell. Both companies buy their drives from Lite-On and if you take a look at Lite-On's M3S SSD, it seems a lot like Corsair's Performance Series Pro and Plextor's SSDs, doesn't it? That's why the hardware of the Performance Pro and M3 is the same—they come from the same plant."

    In fact Plextor is a part of PLDS, a joint venture between Lite-On IT and Philips.
