    Volume write-back cache in Raid 0

    I have two 160GB hard disks in Raid 0 array. In intel matrix, i saw an option of volume write-back cache. Should i enable volume write-back cace in raid 0 disk setup? I don't know what this option does...

    This option is related to some operational speed and performance of the disk in raid setup. I have not used this option too... But it generally helps increasing disk transfer speed when you have disk setup in Raid.

    I really don't know what this option does, but once i enable it on my raid 0 array. I checked with HD Tuner Pro and i was able to achieve 3123MB/s transfer speed, which is sata hard disk's maximum speed. I never had this speed before...

    It is an option regarding speed of the disk by writing the cache, but if you are not sure that if you need it or not, don't enable this option. This may screw up your entire setup...
