How many failed drives can take down a RAID5 array?

The answer, of course, is “two or more”. And it’s not nice when it happens.
Two of the drives on a nice shiny FC array failed at approximately the same time (possibly within about two minutes of each other), and both were in the same RAID5 array. Definitely not good. On the other hand I confirmed that PostgreSQL can run off NFS (both server and client on FreeBSD) without problems so far (this is the temporary setup until we get a new array).
