Random Read/Write Speed

This test writes 4KB in a completely random pattern over an 8GB space of the drive to simulate the sort of random writes that you'd see on an OS drive (even this is more stressful than a normal desktop user would see). I perform three concurrent IOs and run the test for 3 minutes. The results reported are in average MB/s over the entire time:

Random write speed looks to be a bit better with the new firmware. The 80GB G2 being a little faster than the 160GB version for some reason. With enough free space, the Kingston SSDNow V performs similarly to a non-TRIM enabled X25-M G2.

    I've read about some Macbook hacks for the SSD user, but still wonder how I should make my SSD's "new" state last longer.

    I do still wonder if I should use the "Secure Empty Trash" in Snow Leopard? At first, I've partitioned my drive for all available space, but then reduced the HFS partition to 68 Gb or so - will this prolong my drive's "new" state because of Intel's algorithms?
    Should I use "Erase Free Space" in Disk Utility?
    Thanks!

    I would say NO. Secure Erase (of used or free space) will generate (many) more writes which can only make the problem worse, "using up" your reserve space much more quickly than before. At least that's what my intuition says. Maybe somenoe who knows for sure will chime in. Reply

    The Kingston 40GB is available for $130:

    I wonder how many, if any, were sold at $85 (or even $115). I also wonder how this article is repeatedly bumped for minor (and predictable) updates while the incorrect pricing predictions are never acknowledged. The Intel MLC SSDs continue to list for much higher than the given "expected" launch price . . .

    . . . yet that article was never bumped to the top. Even the G1s were priced higher! Props to Anand for keeping the SSD companies honest on performance, but why can't the same be done for pricing?

    If I were going to release/retail a new SSD, I would definitely call Anand ahead of time and tell him an expected price about 50-75% of the real one so he would blindly print it and create demand.

    The new Firmware is out and works properly.
    To test SSD this is a good program, I think.

    Please test 2 X25-Ms with Intel Matrix RAID10 and other Matrix RAID arrays the moment Intel drivers with TRIM come out. Reply

    Another great article, thank you for all the hard work and insightful analysis. Articles like yours help keep the industry honest and responsive.
    I can't wait until they become cheap enough for me to buy two for a RAID 0, and of course for Intel to release new drivers to support the TRIM commands.
