Quoting Atte André Jensen :

> atte@vestbjerg:~$ sudo hdparm -Tt /dev/sda

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.
