That drive should be more than adequate. Mine is a 5400rpm 2mb buffer clunker. Works fine. Are you running anything else on the backup server, besides BackupPC? What OS? What filesystem?

That's a separate disk, not a separate partition of the same disk, right? If it's just a separate partition, I'm not sure how well the OS will be able to allocate wait states to logical devices sharing the same physical media... in other words, what looks like waiting on ad2 may be waiting on ad0. Someone more familiar with device drivers and linux internals would have chime in here.

I may have missed an app out there, though. What are these people switching to, if you don't mind? Re: what must improve is more people helping Craig. He's doing it all for free. I think if it's important enough to have fixed, it's important enough to pay for. Or dive into the code and start making those changes. It is open source, after all.
