My experience with raid5 was a bad one. I had one drive fail on my linux server and didn't get notified for a long time. Then when I went to add another drive and rebuild, another (of the same vintage) went out.

Now, I'm not 100% sure that it wasn't my fumbly fingers that did something to corrupt the drives during reconstruction, but it was a lesson learned.

probably no mistake. One of the most common Nagios monitors I've provided for people is a Linux software RAID monitor. Naturally I haven't kept a copy, but it's pretty simple, just awk /proc/mdstat and alert if the number of good drives changes.
