I decided that snapraid would be the best software raid to fit my needs. I read on the official site that if you use several drives (including the parity drive) of identical size that you wouldn't be able to fill all of the data drives to the brim.
If I were to span the parity drive with a small ssd would it negate this problem? I fully understand that it would add one more point of failure. The reason I am considering this is I will be upgrading to a much bigger ssd which would leave me with several smaller drives that have more than 90% writes available.
I plan to do all of this with 3x4TB Hitachi Deskstar NAS + Crucial M4 128GB or Corsair Force GT 60GB. This will likely be expanded to 5x4TB drives by the end of the year.
My other choice would be to buy one 5TB version of that drive, which is considerably more expensive.
