[root@localhost root]# hdparm -t /dev/hdb
/dev/hdb:
Timing buffered disk reads: 64 MB in 1.42 seconds = 45.07
MB/sec
[root@localhost root]# hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 64 MB in 2.47 seconds = 25.91
MB/sec
И то и другое - UDMA100 на соответствующем контроллере и
адекватном шлейфе. Но hda делает 5400 об/мин, а hdb - на 7200. И
разница не 33%, а куда больше.
