Re: RAID

HW RAID means that all the logic is handles on the controller. The RAID looks like a single disk to the server.

SW RAID means that you have normal drives and that a driver in the Server OS itself is used to handle ll the logic.

SW RAID means you need a lot of CPU to handle the parity(if using RAID5 or 6) and other work. and a crash in the OS means your files are hosed.
Trying to read a SW RAID on another computer / OS is usually not possible/recommended, either.
