    I created a RAID0 strip of four Samsung Spinpoint F1:s, (700 GB each) with Intel's RAID bios. Windows shows the RAID volume as 2,72 TB. Isn't a RAID0 supposed to be the size of one hdd? Intel Matrix Storage console shows the strip as normal and working. All the drivers are newest, off the manufacturers websites and windows shows no missing drivers. Unshure to put any data on it...

    Windows XP x64
    Gigabyte GA-X48-DQ6
    Kingston 4GB
    Radeon HD 4850

    RAID 0 (striped disks) distributes data across several disks in a way that gives improved speed and full capacity, but all data on all disks will be lost if any one disk fails.

    what you probably wanted was raid 5, striping with parity

    A RAID 5 is calculated like so, where n is the number of drives and m is the size.

    Total size of array: (n-1) * m

    So, in your case, you would have (4-1) * 700. This should give you a drive of approxiamately 2 TB, with parity. Good performance with fault tolerance. Definately the best way to go if you need fault tolerance. If not, then stripe away and enjoy the performance.
