    Why is it so much slower when using the same controller as other drives?
    Is it due to the NAND flash being used?
    I know Anand had an article showing dramatic speed diffrences in the various models of Flash memory (you wont know what you get when buying the drive, akin to what sort of DRAM is actually on the stick of RAM you buy...)

    You should know better than to ask questions before reading :p

    It was mentioned a few times in the review. The Pyro uses asynchronous NAND flash memory while the Vertex 3 uses pricier synchronous memory.

    I'm reading 66bps on the drive's sticker. xD

    Steve: that was not what I meant.
    The differences in async vs sync memory should not make such a tremendous difference.
    There must be some more difference, there are other drives using async memory and posting much better speeds.
    Anandtech did a good writeup on different NAND memory and their effect on drive performance.

    The same NAND in the same configuration and node size can still have a large impact on performance, as you can see 2 pages into that article...

    What firmware did you use for the M4 ssd? Vanilla or version 09 which has upto 25% boost in perfomance. And priced @ $385. For 256 gig one.

    Which drives using async are posting much better speeds?

    Who can navigate Corsair's SSD firmware downloads to tell? They're officially buried deep in their public forum and reliant on third party software to use.

    Its a Crucial drive the m4. To answer godrilla's question we used the first release firmware when testing.

    thanks for the response, if you used the later firmware (09) the raid 0 setup would look even worse.
  11. From the article: "Once formatted in Windows, the original 120GB drops to 111GiB, meaning you lose 7.5% from the GB to GiB conversion."

    Nothing was lost. 120 GB is 111 GiB.

    It's like going to a cable vendor and asking him for 8 km of wire, and they give you a reel with 5 miles of wire on it. You got what you asked for.

    The only confusing issue is that Windows advertises sizes in GB, but measures them in GiB.

    This is why e.g. a 500 GB harddrive appears in Windows as 465 GB, it's not, it's 465 GiB.

    You haven't lost anything.

    Yep, we get it. Windows still displays it as GB so to the user they went from 120GB to 111GB. We explained that it is GiB so yes while lost is not technically right your argument is probably best directed at MS.
