I am looking for a RAID controller based on the following, I have tried some local sources here in deepest darkest Africa without much luck.
6 x 2TB WD Green SATA drives
RAID 5 (seems to be the best solution without losing a lot of space)
Hardware Raid (from what I've read it appears better)
OS & MB are currently 64bit
Running 2008 or 2012 Server
This is running a home media/file server so some redundancy is great however everything is backed up, the card should be compatible with 3TB and 4TB drives.
