Is it really a good idea to use RAID 5 on a database? If the database is large enough rebuild time can be more lengthy than a straight restore and under many RAID 5 setups you have the added problem of slower write performance.

Hell no. Had I been in involved in that setup it would have been RAID 10 or RAID 50. Actually, had there been some planning there would have been a second array and it would not have been physically co-located in the same rack as the first so when the cooling or power inevitably fails it won't take out both. But, you know, not my circus.
