Thanks - backups will be saved to a file share on a NAS.

My question is whether there is a performance gain that might be realized by separating the physical disks from:

14 drive RAID 10 holding data / logs and tempdb

to:

10 drive RAID 10 holding data

2 drive RAID 1 holding logs

2 drive RAID 1 for tempdb

The recommendations that I've seen suggest that separating them is advantageous.

It seems to me that the 14 drive RAID 10 would give me the best write IOPS, and if logs or tempdb were at all write intensive that a 2 drive RAID 1 might be a bottleneck.
