    Hi! I am running an Adaptec 29320LP adapter with 2 Seagate st336754lw 36gb 15k hard drives but the hard drive speed is maxing out at 70gb per second!! Does any one know how do i config to get the full 320 gb per second or at least close to????

    Any help would be apriciated.

    Because the interface supports that speed doesn't mean the drives can actually sustain a transfer rate close to that. Same as with PATA and SATA IDE drives. But 70MB/s does seem low. Are the drives in RAID or just seperate individual drives?

    Also how are you measuring the speed? Try HDTACH: http://www.simplisoftware.com/Public/index.php?request=HdTach

    hi, I used that program you said to test and is maxing out at 80mb/s. they are running as single drives not raid....... will they run faster as raid?

    80Mb/s is fine. RAID-0 would improve performance slightly but you'd lose all you data when you created the array unless you imaged/backed up the drives first and then restored them.
