I am looking to get a large RAID 5 or 6 volume around 14TB setup. It will serve as an archive server images. I am trying to do this on a budget so i don't just want to throw money at the solution, but at the same time i want something i can count on. Reliability is my top priority with cost coming in a close second.
Does anyone have a recommendation as far what drives i can get away with? are basic 2TB drives probably ok in a RAID6 because of the global hot spare? i can purchase those for about $70 each on newegg.com Will using low cost drives instead of enterprise drives put me at a high risk of having problems?
What entry level controller card will get me in the door on this? I'm looking at the adaptec 5805 or 51245. Will either of those do a good job? is the 51245 overkill? I plan on using a SFF-8087 to SATA breakout cable on these, is that something that might be a problem? Should I use a server case with a back plane instead? Is there anything I may be overlooking from what i have said. All i am really considering critical to what i'm doing is what i've mentioned. Should it matter, I plan on managing this from a Win7 Pro box.
