 |
|
I have 2 sata harddisks, one of them (/dev/sda) being 3 gbit/s (which's about 350mb/s), accoding to it's manual. But hdparm doesn't say so. Also, when copying from one drive to another, the speed is 30mb/s on average. Is there anything I can do to speed up the disks?
Here's the output of some programs that might be useful:

| That's usual HD speed. 3Gbit is the THEORETICAL max, which you're never going to get near. |
