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.

    Thanks guys :)

    Take care,
    Anand

    Since I've been wondering about the free space issue, will there be a test where a drive is benchmarked vs. the amount of free space available? My guess is that the graph will be an exponential decay with the "noticeable" regime at 20% free space. Anyone cares to do this (say, at 90%, 80% ... close to zero free space)?

    So, without TRIM, is there anything else G1 owners can do? Can I manually wipe the drive and reinstall my OS every few months? If so, should I?

    I have the G1 and in Anand's previous SSD Anthology article he tells how to get back to 100% performance using HDDERASE.

    This is total crap that Intel is not supporting the G1.

    Buy the G2, clone the G1 to it and sell the gen 1. Really. It is not a big loss of money to do it.

    Basically, you suggest we pass our problem on to someone else who is less informed. It's called "Ethics". Look into it.

    Just because Intel has none doesn't mean I'm going to abandon mine.

    The only option you, a G1 owner, have to make your drive's performance back to ~100% is to do a full format of the drive. I'm pretty sure it would have to be done very frequently, each time you write 80/160GB of data to the drive... nothing else you can do, sorry =(
    Intel's wipe ultility (SSD Toolbox) only works with the G2 (for use with Windows XP/Vista) and TRIM only works with the G2 as well (for use with Windows 7-to replace the Toolbox)... =(

    One can always try the Indillinx tool, after making a full backup, of course. Heck, 80GB would be less than two blu-rays.

    Another great article by the one and only Anand Shimpi, king of SSDs
    So, basically Intel made a very stupid move by only allowing SSD Toolbox AND TRIM on G2 drives. I would like to know if its due to architectural changes (perhaps?), maybe you know it but can't reveal it to anyone... if I weer you i would edit out the part when you say the G3 are coming next year... or else Intel will kill you, they just lost a custumer for the G2 (me)

    But would it make sense for them to release the SATA 6 G3 drives next year if their on-board ICH10 and MCH P55 does not support it? Maybe the P57 and X68 will? Who knows?

    I'll still be waiting for those Gulftowns... =D

    Don't think its that much of a secret that we will se a new generation next year. We need a version that uses Sata3 (6Gb).
