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.

    The 4k thing was a way to quantify the stuttering problem on some drives, as if he had just said "the drives stutter" but only shown objective results that look good (due to sequential write speeds), then people would have claimed he was making stuff up to be an intel fanboi as well.

    Human-observed delay time is really all everything comes down to. 4kb performance and IOPS are interesting to look at, but they're severly inadequate. If I remember right, RAID0 tends to look awesome in benchmarks, but offers virtually zero real-world benefit.

    So screw the benchmarks get and out a stopwatch. Measure what matters: boot time, time to launch various applications, media encoding time, and the time to copy files. Quantified seconds are a helluva lot more meaningful than IOPS.

    You mean something like this: http://www.anandtech.com/storage/showdoc.aspx?i=34...">http://www.anandtech.com/storage/showdoc.aspx?i=34...

    Yep, something like that, but with more categories. I think this is a good set:

    1. Boot time
    2. Time to launch applications
    a) Firefox
    b) Google Earth
    c) Photoshop
    3. Time to open huge files
    a) .doc
    b) .xls
    c) .pdf
    d) .psd
    4. Game framerates
    a) minimum
    b) average
    5. Time to copy files to & from the drive
    a) 3000 200kB files
    b) 200 3.5MB files
    c) 1 2GB file
    6. Other application-specific tasks

    Imagine if we had a table of this data and all of the SSDs and a conventional HDD. That would be so much more useful than all the charts in the existing article.

    Finally, an SSD that I can afford and makes sense to me. Anyone can afford a POS SSD drive, but this one doesn't look crippled too much. The writes I'm not too worried about, but the stuttering and performance degrading is not what I want to pay a premium for.

    I'm hoping by Jan-Feb (when I could afford one) that Kingston will have the trim support and upgraded firmware. Then I'll jump on it!

    Just picked mine up yesterday.. Kingston 40gb bootdrive desktop kit.. Has 2CV102HA firmware .. i.e. TRim support already.. be on the lookout for it. .dont know if its all drives now or just some.

    What I read from Intel about the Optimizer suggests it is not needed in Windows 7 or not needed to actually run it. Anyone understand what Intel is saying here:

    "When using the latest Microsoft Windows* 7 operating system with Microsoft AHCI storage drivers the OS will contain native support to execute the Intel® SSD Optimizer on an Intel SSD without requiring any user interaction."

    "Microsoft Windows* 7
    Microsoft* AHCI
    Native OS support (Intel® SSD Toolbox not required)"

    No, that was part of the point of this article, that TRIM is supported natively in 7. It is not in earlier OSs, so they have the manual TRIM tool.

    Are all the Kingston SSDNOW drives X25 based in design with just different amounts of memory?
