Hi folks,
Is there any way to tune up SCSI HD parameters to make its transfer rate faster?
I've entry like this on my /var/log/messages

Even it said 320.0 MB/s but I got only 88.54 MB/s.
[root@fc6 ~]# hdparm -tT /dev/sda3
/dev/sda3:
Timing cached reads: 2824 MB in 2.00 seconds = 1412.18 MB/sec
Timing buffered disk reads: 266 MB in 3.00 seconds = 88.54 MB/sec
Timing cached reads: 2824 MB in 2.00 seconds = 1412.18 MB/sec
Timing buffered disk reads: 266 MB in 3.00 seconds = 88.54 MB/sec
Any ideas are greatly appreciated. Thanks in advance.
