Sequential Read/Write Speed

Using the 6-22-2008 build of Iometer I ran a 3 minute long 2MB sequential test over the entire span of the drive. The results reported are in average MB/s over the entire test length:

    The data compression accelerates the writing speed, but, the question is:

    The OS still considers that the non written space is occupied?

    Or the compression releases the non used space?

    I suspect that the unused space is marked anyways as used space, but I would like a confirmation.

    If Sandforce is largely about writing fewer bits to the NAND flash, wouldn't it also follow that turning on OS level compression would also work as well?

    Also, I'd be interested to know if using OS striping is ok with TRIM, as there aren't any controllers out there that work with TRIM when SSDs are striped.

    Hey Anand,

    have you put a Sandforce based disk into a mabook and let it running only on OSX?

    Can you say something about speeddrops without Trim or does the build in "gc" wich isn't "gc" can handle it accurate?

    i get my hands on a new I7 macbook and want to put a sdd into but i don't know if i should go for the old intels, use the new sandforce or wait some moths to see what intel does and how stable sandforce is without trim.

    What is the verdict with these Vertex 2 100g SSD drives???

    Because I just got one in the mail from OCZ as a replacement for my dead Vertex LE 100G SF1500

    Anand, care to comment as they have been in your desktop for ~ 5 months now.. or anyone who owns one???

    Thanks,

    529th

    p.s. i am considering a main rig install with this, booting out my ever reliable 150g 1st gen Raptor...
