On my P4P800 system with 3 drives, here are stats

3ware Escalade 7006 card connected to 32 bit PCI 2.2 with 133MB/s max transfer, 2 WD 
80GB Caviar drives RAID 1

# hdparm -tT /dev/sda
/dev/sda:
 Timing buffer-cache reads:   2956 MB in  2.00 seconds = 1478.00 MB/sec
 Timing buffered disk reads:  138 MB in  3.01 seconds =  45.85 MB/sec

80GB WD Caviar single drive connected to IDE on MB:

# hdparm -tT /dev/hda
/dev/hda:
 Timing buffer-cache reads:   2908 MB in  2.00 seconds = 1454.00 MB/sec
 Timing buffered disk reads:  140 MB in  3.02 seconds =  46.36 MB/sec

This is a dev machine where I'm not too concerned about performance, and I don't know 
if these numbers are good or bad (relative to other IDE RAID solutions)...just posting 
the stats. Not much load when I ran the tests.
