Hi, According to RAID theory, the READ performance with RAID0, 1 and 5 should Be faster than one with non-RAID. I tested it on Redhat linux(ES) on Pentium PC, but they are almost same. I am using RocketRAID404(HPT374)PCI card to connect 4 master IDE Drivers. Ideally it must be 2 or more times faster on RAID0/1/5. Do we still have an issue on parallelism on 2.4 and 2.6 Linux kernel?
