What are the different types of RAID controllers?

RAID controllers are available in two main configurations: as busses or controller cards and external peripheral devices. Bus-based or controller card hardware RAID is a conventional type of hardware RAID, and is most commonly used for lower-end systems.

Is a RAID controller necessary?

RAID 5 and 6 will get you significantly improved read performance. But write performance is largely dependent on the RAID controller used.
