I do a fair amount of video editing and encoding and I've finally gotten around to looking into an alternate solution to my 3x external hard drives. I have an old full tower that supports 6 internal drive bays and plan to use an old 80GB drive in on of them as an OS disk.
There seems to be allot of support for RAID 5 however I'm sure if this is the right solution for large files.
The way I understand RAID 5 to work is that it uses a computation to produce parity across all the drives allowing one drive to fail and the integrity of the data to still be intact. The one big advantage I see is that you don't loose out on allot of disk space. However I've read that it's inefficient with large file sizes and that should a drive happen to fail rebuilding the replacement drive can be an all day affair.
I've caught snippets of RAID 3 and heard this suggested as a superior RAID solution for large files. The way I understand this to work is that instead of doing a computation to create the parity one dedicated disk is used.
My questions about the two are these.
Do they both support varying drive sizes?
How much space is "lost" do to parity with each solution?
What is the performance gain with a RAID 3 over a RAID 5 when storing large (200mb and up) files?
Anybody who has had experience with RAID 5 or RAID 3 or both would be appreciated. Also I plan to use a control card(s) to handle the raid as my mobo only supports 0, 1 any suggestions on this front would be welcome as well.
