Those numbers seem about right. The three disks in my PC at work show:
sda: Samsung SpinPoint SP0411C 40GB SATA/150 7200RPM 2MB HDD

/dev/sda:

  Timing cached reads:   2920 MB in  2.00 seconds = 1460.18 MB/sec

  Timing buffered disk reads:  150 MB in  3.02 seconds =  49.72 MB/sec
sdb: Seagate Barracuda ST380011A IDE 80 GB

/dev/sdb:

  Timing cached reads:   2836 MB in  2.00 seconds = 1417.47 MB/sec

  Timing buffered disk reads:   80 MB in  3.02 seconds =  26.45 MB/sec
sdc: MAXTOR 4G120J6 IDE 120.0GB

/dev/sdc:

  Timing cached reads:   2920 MB in  2.00 seconds = 1460.83 MB/sec

  Timing buffered disk reads:   80 MB in  3.07 seconds =  26.09 MB/sec
I think the IDE drives should be faster but I haven't got an ATA-100

cable so that might be the culprit.
