Hi,


I wondering if I want to know if setting up a raid 0 on my kt7-raid will get me more performance or stick with a cheetah 10k on a ultra2 scsi card.
The following drives is what i want to put in
kt7-raid 0 with 2 ibm 20.5 gig 7200rpm
or
tekram u2w with 18gig cheetah 10k rpm

This is really going to depend on what you use your system for and how fast your CPU is. I use the RAID setup as a gamer. The RAID implementation on the Abit board is still mostly software based, so CPU utilization is going to be alot higher than with SCSI. I generally get around 25% CPU utilization in HDTach. That said, I love not having to wait long for my games and large file transfers to load. With the speed of a T-bird I really don't notice the high CPU utilization. A single drive, SCSI or IDE, to my knowledge, can not sustain transfer rates much more than 30-40 MB/s. With my RAID array, HDTach is reporting transfer rates of 44-80 MB/s, and burst rates are off the chart at over 85MB/s.

Hope this helps!
