Likewise here, I get:

/dev/sda:
 Timing cached reads:   1752 MB in  2.00 seconds = 875.60 MB/sec
 Timing buffered disk reads:  180 MB in  3.02 seconds =  59.66 MB/sec

/dev/sdb:
 Timing cached reads:   1782 MB in  2.00 seconds = 891.09 MB/sec
 Timing buffered disk reads:  198 MB in  3.01 seconds =  65.84 MB/sec     

Little bit slower, but not much.

These are PATA drives, the "sd" is Kubuntu doing its thing.

For comparison, a scsi hardware RAID5 system:

/dev/sda:
 Timing cached reads:   1030 MB in  2.00 seconds = 514.26 MB/sec
 Timing buffered disk reads:  252 MB in  3.02 seconds =  83.32 MB/sec

And a RAID0 LVM system:

dev/mapper/VolGroup00-LogVol01:
 Timing cached reads:   1310 MB in  2.00 seconds = 655.05 MB/sec
 Timing buffered disk reads:  328 MB in  3.00 seconds = 109.25 MB/sec

YMMV of course.
