Is there anyway to enable NCQ on CentOS 4.6? I guess anouther question is on a somewhat high activity mail server with a single SATA2 drive will it do any good?
Matt
I doubt it will make a BIG difference, but you might be looking for trouble running a highly active server of any kind on a single spindle.
Some decisions made in past are hard to undo down the road. Would like to move to CentOS 64 5.x with RAID but moving everything too a new box is a very severe pain. I have to move it to new IP space shortly and hate the idea of that.
Matt
You could easily move to a software raid1 with very little downtime and a few reboots. It might also help slightly with read latencies, but wouldn't help with writes.
