Gahn said:Raid wont in any manner speed up your pc effectivness, RAID technology it's only for securing yourselves from data loss ^^ And btw there aren't Raid HDs, there are Raid Controllers that use normal disks (but u want em quicker than normal ones so a SATA Raid would use 7200 rpm hds).
RAID 0 will actually speed up I/O performance quite a bit, no good as a data saver though.
