I've used Linux's md raid a couple times before, but having suffered a hard drive death this weekend, I have some questions about performance and recovery, if anyone's dealt with it.

I'm thinking of getting a pair of 500GB drives, putting one in my Linux box, and the other in a Firewire case, and setting up a software mirror between the two. Would this be asking for performance nightmares? I.e., do writes only return as successful once all mirror copies have been written, or only when the fastest copy has been written?

Slightly related, how badly does the system suffer when you bring a mirror up from degraded (i.e., only one drive is present) by replacing the second drive and doing a rebuild?

For my purposes, would I be better served by just keeping the drive in the firewire box turned off until I want to do a backup, and then just use rsync, or will the software mirroring actually do what I want without torturing the I/O performance because of the firewire mirror?

Thanks,

Gregory
