A bit more information. On the slow system:

# hdparm -Tt /dev/sdb

/dev/sdb:
Timing cached reads: 27784 MB in 1.99 seconds = 13934.26 MB/sec
Timing buffered disk reads: 468 MB in 3.01 seconds = 155.63 MB/sec

# hdparm -Tt /dev/sda

/dev/sda:
Timing cached reads: 27776 MB in 1.99 seconds = 13930.08 MB/sec
Timing buffered disk reads: 584 MB in 3.00 seconds = 194.66 MB/sec

On a system acting as expected:

# hdparm -Tt /dev/sdb
/dev/sdb:
Timing cached reads: 6852 MB in 2.00 seconds = 3427.26 MB/sec
Timing buffered disk reads: 312 MB in 3.01 seconds = 103.56 MB/sec

So at this level they seem to be okay. Not sure what this tells us.
