some way to tell if the drives are going bad or speed it up consistently
if they aren't?
Only thing I can think is if there's a lot of activity on the disks, with many, many gigs of files added or deleted.

No, I'd expect the issue with any activity that would keep pulling the heads away from the current track being sync'd - but when it is slow it doesn't speed up even if I unmount the device.
