As long as only one drive dies in a RAID 5, you can take as long as you 
want. But if a second drive happens to die in the meantime, you're sunk. 
If you go to RAID 6, you're only out of luck if three drives die at once.

After spending way too much time a few years ago recovering data from a 
failed drive, I've since gone to RAID 5 and now 6. Is it overkill? 
Perhaps. But this way I can have a drive fail, send the bad unit back 
for RMA and get the replacement--all while still having a one-drive 
safety net.

Two other things I've found very helpful are smartmontools and 
raid-check. Between them, they help to point out a drive that is likely 
to fail before it becomes critical.
