    some sata2 drives have a jumper on the back that allows them to switch between the two modes. It's there for "compatibility", but good to check and make sure its on the faster one.

    The difference being the interface speed... SATA1 150MB p/sec & SATA2 300MB p/sec
    Even the fastest sata drive is not going to be able to take advantage of SATA1 speeds and the only real benefit is if you are going to raid 2 or more fast HDD's together.

    If its only one or two drive's then SATA1 is more than fast enough.
    If you using 4 or more raptorsX's then SATA2 will not bottleneck them due to the interface speed

    Burst (cached data) on SATA 2 is much faster. Just run one of the HDD benchmark tools, like HDtune or something, and look at those burst speeds.

    thats a valid point I guess, though most HDD caches are between 8 & 32MB and youd get a more noticeable boost from having more ram. Its kinda like the difference between PCI Express 1.0 & 2.0 really... im sure when solid state drives get a bit faster it will be a lot more usefull.
    computertechy says thanks.

    SATA2 is faster! SATA 1 is common and slower than SATAII
