I am looking at setting up a Raid 5 array. Only problem is I can't find any raid 5 controllers, all I can seem to find is raid 0 or 1. Also can I raid 2 hard drives that already have data on them or can I only raid new hdd's?
Cheapest hardware raid solution you'll get are a few hundred, so keep looking past the cheapy standard raid cards you get in yum cha pc shops. Look for brands like highpoint, Adaptec, 3Ware, and Areca for good hardware raid cards.
