freenas FreeNAS Harddrive Configuration. Mainly software setup.
ignore my previous posts about unRAID, I understand what they are doing now. A normal RAID5 stripes an incoming file across all the storage disks, and computes the parity of the whole "row" of blocks. unRAID stores the file on just one disk,a nd computes the parity of the whole "row", but said row contains multiple files instead of just one file (this is simplified, a block isn't have to be just one file nor does one file fit in a single block sometimes)
as far as the original request goes, for non-redundant storage that keeps the data of the remaining drives in the event that one drive dies, this doesn't exactly fit the bill (because it IS redundant, although files are only stored on one drive each). But in terms of the most efficient way to use 4x4TB drives and 1x2TB drive, this might work the best. now if I understand properly, you still have to sacrifice a 4TB drive as the parity, but this would give you 18TB out of 22TB, versus I'm not sure what the best you could do with FreeNAS would be - you might be able to get 18/22 if using two separate RAID-Z1s made out of 4x2TB and 5x2TB.
