The same test on a scsisetup much like the above just with scsidisk :
*:~# hdparm -T /dev/sdb5
/dev/sdb5:
Timing buffer-cache reads: 128 MB in 0.95 seconds =134.74 MB/sec
/dev/sdb5:
Timing buffered disk reads: 64 MB in 3.42 seconds = 18.71 MB/sec
When it comes to real world test my scsibased system is almost twice
as fast as the idebased one :)
