Expansion Advice

Calling all nerds…. I need help… I have a big problem, I need to find a cost efficient way to “fix” my poorly configured NAS server.

Here’s the dilemma: I have a server with 9 Hard drives: 6x3TB drives, 3x2TB drives, it’s configured to about 66% efficiency beacause I acquired all of those drives over time… long story short, I need to “Temporarily” store 11TB of stuff somewhere.

My machine can only hold 3 more drives without significant modification, and my budget to fix is about $300, which limits my purchases to about 3x3TB drives…

So my questions are as follows: does anyone have any large hard drives laying around that I can borrow?

Does anyone know of any good hard drive deals?
