It won't make the filer crash, but you may not get any performance benefit out of the faster drives.

If you're keeping 2 spares, one of each would probably be best.

We just bought two new shelves of ATA drives to enlarge an aggregate on our R200 and the new drives are all 7200 RPM while the old drives are 5400 RPM, same size though.

It looks like ONTAP will let me add the new disks to the aggregate if I use the -f (force) flag. I'm inclined to force, unless this ruin performance or make the filer crash.

We keep two hot spares, so should I have one of each RPM?
