Performance vs. Transfer Size

All of our Iometer sequential tests happen at a queue depth of 1, which is indicative of a light desktop workload. It isn't too far fetched to see much higher queue depths on the desktop. The performance of these SSDs also greatly varies based on the size of the transfer. For this next test we turn to ATTO and run a sequential write over a 2GB span of LBAs at a queue depth of 4 and varying the size of the transfers.

    NIce to see the review, shame you never looked at the Vertex 3 Max IOPS versions though. Any chance you can get hold of them and report on the differences?

    Still waiting on my review sample, I'm guessing it'll be next week :)

    Take care,

    Any Idea when the Samsung 470 review will be up?? Quite interested in your take on this drive.

    Realyy great review, but in my case it raises even more doubt. I was about to pull the trigger on the 120GB version of the Intel 510, but now I don't know what performance to expect at all.

    Do you think you'll also be able review the lower-capacity Intel 510/320 drives in the near future?

    The 120GB 510 is next on my list :)

    Take care,

    That's great news! Looking forward to the review :D

    I have a question regarding TRIM: if I install both Windows 7 (TRIM support) and OS X (no TRIM) on the same SSD, will that potentially cause problems?
  • HilbertSpace - Friday, May 6, 2011 - link

    Good question, I'm guessing it would only run TRIM on the windows partition and not the Mac one.

    I don't need more than 120GB. Any chance of a review of Intel's 120GB version?

    Any word on a new firmware rls date? see http://www.xtremesystems.org/forums/showpost.php?p...

    Anyway waiting eagerly for M4 and Max IOPS @ 120GB reviews since those 2 seem to be the most interesting given the price/perf ratio.
