I would rather expect an increase of 50% in practice with a 2-disk stripeset, in this case : (27 + 31) / 2 * 1.5 i.e. a transfer rate of approx. 43.5 MB/sec. Having the discs on the same cable or not didn't make any difference for me. No bottlenecks since we don't exceed the bandwidth of each IDE channel (133 MB/sec, i.e. 66 MB/sec per single disk). -- Michael Linux: Because rebooting is for adding new hardware. -------------------------------------- Gentoo Linux 1.4 (Intel) Kernel 2.4.20 [SMP,ACPI,RAID] 12281.44 BogoMIPS -- [EMAIL PROTECTED] mailing list
