запусти как
smartctl  -d ata --all /dev/sda

Кстати у меня похожий винт и raid1.
Model=ST3120026AS                             , FwRev=3.18
Model=ST3120813AS                             , FwRev=3.AAH

$ sudo hdparm  -tT --direct /dev/sda /dev/sdb /dev/md0

/dev/sda:
 Timing O_DIRECT cached reads:    96 MB in  2.00 seconds =  47.99 MB/sec
 Timing O_DIRECT disk reads:  166 MB in  3.03 seconds =  54.83 MB/sec

/dev/sdb:
 Timing O_DIRECT cached reads:   260 MB in  2.01 seconds = 129.65 MB/sec
 Timing O_DIRECT disk reads:  166 MB in  3.01 seconds =  55.07 MB/sec

/dev/md0:
 Timing O_DIRECT cached reads:    80 MB in  2.00 seconds =  40.00 MB/sec
 Timing O_DIRECT disk reads:  172 MB in  3.02 seconds =  56.87 MB/sec

То есть в рейде чуть быстрее.
