Already tried this, but it doesn't help The actual settings (same on /dev/hdc):
bash-2.04# hdparm /dev/hda
/dev/hda: multcount = 16 (on) I/O support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 59556/16/63, sectors = 60032448, start = 0
bash-2.04# hdparm -tT /dev/md0
/dev/md0: Timing buffer-cache reads: 128 MB in 1.30 seconds = 98.46 MB/sec Timing buffered disk reads: 64 MB in 3.14 seconds = 20.38 MB/sec
bash-2.04# hdparm -tT /dev/hda3
/dev/hda3: Timing buffer-cache reads: 128 MB in 1.31 seconds = 97.71 MB/sec Timing buffered disk reads: 64 MB in 2.26 seconds = 28.32 MB/sec
