What should I do to enable SATA II on this disk ?

Rep:
Ok I understood this.
I have 6 ports SATA III on the mobo :
-ata1 /dev/sda with SATA II interface 3Gbps
-ata2 /dev/sr0 CD/DVD ROM with SATA I 1,5 Gbps
-ata3 dummy
-ata4 /dev/sdb with SATA II interface 3Gbps
-ata5 nothing
-ata6 nothing
So why when I perform sequential read test I get below results ?
Code:
[root@USER1 ~]# hdparm -t /dev/sda /dev/sdb
/dev/sda:
Timing buffered disk reads: 300 MB in 3.02 seconds = 99.39 MB/sec
/dev/sdb:
Timing buffered disk reads: 340 MB in 3.01 seconds = 112.78 MB/sec
/dev/sda disk
Code:
[root@USER1 ~]# hdparm -I /dev/sda

Is it possible that because sdb is bigger then sda, it has better reponse time and that why its throughput is better ?
