Well, IDE is not that bad... /dev/hda: Timing buffer-cache reads: 128 MB in 0.68 seconds =188.24 MB/sec Timing buffered disk reads: 64 MB in 3.20 seconds = 20.00 MB/sec /dev/hdb: Timing buffer-cache reads: 128 MB in 0.67 seconds =191.04 MB/sec Timing buffered disk reads: 64 MB in 4.01 seconds = 15.96 MB/sec -- Meir Kriheli
