Question: Hi guys! I’ve recently cleaned up my home work area. I found a few hard drives and thought I’d try setting up a RAID. The HDD’s are all WD Blues (1 4TB 5400rpm, 2 2TB 5400rpm, and 1 1TB 7200rpm (I do not remember where I got this one)). I’ve tested them and all are working. Data on them have been backed up on my current drives. I was wondering if the size and speed differences might be an issue? Thanks!

That combination will not work in any RAID array.

4 + 2 + 2 + 1 + RAID 0 = 4TB RAID array size
4 + 2 + 2 + 1 + RAID 1= 1TB RAID array size
