    The write/erase cycle for SSD is limited, it could only stand for 1,000 to 10,000 write cycle or a maximum of 100,000 cycles. A conventional hard disk could stand 1-5 million write cycles. This means that the performance of the SSD will decrease during time and usage. ( is this true by any chance?)

    This is true. And as the cell size gets smaller, the # of write cycles decreases unfortunately.

    However, the firmware works around that using unallocated cells (much like a HD does in fact since they all contain inperfections as well). That combined with nternal ware levelling means that on todays 34nm SSDs you should get something like (I'm paraphrasing here) 20 gig of writing a day every day for 5 years straight.

    Here is a quote talking about Intels x25-m drives (using cells with 5-10k write cycles):

    "Using a write-amplification factor of 1.1 and a wear-leveling efficiency factor of 1.1, 20GB of write-erase per day for five years should consume only about 550 cycles on an 80GB X25-M."

    Article here:
    Intel's X25-M solid-state drive - The Tech Report - Page 1

    So for the curent crop of SSDs, they should perform very well for a long time when used in most "normal" ways. If the drive is a temp cache drive used for some large database indexing or something then yes it would probably burn out pretty fast, like months instead of years.

    Revodrive


    I just loaded everything on the new drive and tested it. I must say I have never seen a SSD this fast in my life!

    Those are some pretty impressive numbers. Thanks for sharing your experience with the drive.

    Peace

    For future reference you can just enable AHCI in the BIOS before installing the OS on the affected drive. The hack usually comes in play if you don't do this before installing the OS, or if you have problems installing the OS with AHCI enabled in the BIOS, thus being forced to use IDE to get the OS to install.

    Hello Mike,

    I have the RevoDrive X2 160GB, and I'm not hitting anywhere near that speed. I know it's a bit slower than the 240GB model, but shouldn't be that much.

    I used the 64 KB block size while doing the test. Did you use a different size?

    You have practically the same motherboard as I do. What PCI-E slots (1, 2, or 3) do you have your RevoDrive and graphics card in? I have the graphics card in PCI-E 1 (closest to CPU), and the RevoDrive in PCI-E 2 at 16x16x1.

    Did you make any BIOS setting changes other than to AHCI?

    Test using 64 KB block size:

    Test using 8 MB block size:

    Shawn, I think HD Tune is not a good reliable tool for the measurements. It seems to do strange jerking things. I prefer Atto which gives more consistent results.
