I've heard that the write performance of RAID 5 can be appalling at times. While I want the redundancy that it provides I don't want to sacrifice my database insert/update times.
Is this something I should be worried about and if so, what would be the...

When between performance and space.
Every RAID5 write will cause at least 3 writes (plus a CRC calculation) .

All of a sudden, the power supply of a server started to smell real bad. One of the hot swappable power supply units died. We replaced it, booted up Windows Server 2003 to find out that 2 out of 4 drives in a RAID 5 configuration had died.
We're also ...
