it should be better that you plan different disks for os, data, log and temp<br />
data disk should be raid 5 or raid 1+0 depending on your need and write performance..<br />
log and temp disks should be raid 1<br />
os disks depends on your hardware possible raid 1 or raid 1+0<br />

What about using multiple RAID 1 volumes instead of RAID 5 or RAID 10 for the data files?

Thanks for the input. &nbsp;I am going to go with a 6 disk RAID 10 volume for the data files, and two mirrored volumes for TL and OS.

Hi,<br />
<br />
I'm going to be setting up a new server soon and I have two choices to consider regarding the hard drive configuration. &nbsp; For the data files, I need to use a RAID 5 array. &nbsp;For the operating system and transaction log, I can either set up two separate mirrored volumes (one for OS and one for TL), or a RAID 10 volume for the both of them to occupy. &nbsp;Suggestions?
