and giving up to 200Mb/s on a pretty old mobo (see cached reads) with raid5:

annwn:~# hdparm -tT /dev/sd[bcde]

/dev/sdb:
Timing cached reads: 950 MB in 2.00 seconds = 474.23 MB/sec
Timing buffered disk reads: 228 MB in 3.00 seconds = 75.93 MB/sec

/dev/sdc:
Timing cached reads: 1020 MB in 2.00 seconds = 510.01 MB/sec
Timing buffered disk reads: 228 MB in 3.01 seconds = 75.76 MB/sec

/dev/sdd:
Timing cached reads: 1022 MB in 2.00 seconds = 510.69 MB/sec
Timing buffered disk reads: 228 MB in 3.01 seconds = 75.79 MB/sec

/dev/sde:
Timing cached reads: 1016 MB in 2.00 seconds = 507.92 MB/sec
Timing buffered disk reads: 228 MB in 3.02 seconds = 75.48 MB/sec
annwn:~# hdparm -tT /dev/md0

/dev/md0:
Timing cached reads: 1020 MB in 2.00 seconds = 509.96 MB/sec
