I wonder... I get different readings on different partitions and file
type even though the hard drives are identical. They are jumper
configured for primary and slave:

/dev/sda:
 Timing cached reads:   1034 MB in  2.00 seconds = 516.60 MB/sec
 Timing buffered disk reads:   84 MB in  3.06 seconds =  27.49 MB/sec

/dev/sdb:
 Timing cached reads:   1062 MB in  2.00 seconds = 530.69 MB/sec
 Timing buffered disk reads:  144 MB in  3.02 seconds =  47.69 MB/sec

sdb is a Windows drive. I find that if you do the same with each
partition on the same hard drive you will get different readings as well.

/dev/sda1:
 Timing cached reads:   1044 MB in  2.00 seconds = 522.09 MB/sec
 Timing buffered disk reads:   84 MB in  3.05 seconds =  27.50 MB/sec

/dev/sda5:
 Timing cached reads:   1014 MB in  2.00 seconds = 506.46 MB/sec
 Timing buffered disk reads:   58 MB in  3.08 seconds =  18.84 MB/sec

/dev/sdb1:
 Timing cached reads:   1070 MB in  2.00 seconds = 534.98 MB/sec
 Timing buffered disk reads:  156 MB in  3.01 seconds =  51.85 MB/sec

/dev/sdb2:
 Timing cached reads:   1050 MB in  2.00 seconds = 524.59 MB/sec
 Timing buffered disk reads:   96 MB in  3.02 seconds =  31.82 MB/sec
