Sean Reifschneider Subject: Drive sizes. |
I'm using a variety of drive sizes for ZFS, mostly 250GB and 500GB, mostly because these are what I already have available. If I were buying drives for a new storage box today I'd probably use 5 2TB 5400RPM drives to give me 6TB of storage with RAID Z2, slower but also using less power.
Of course, RAID Z2 makes smaller drives more attractive, because of less overhead (10 1TB drives would have 8TB data 2TB parity, 5 2TB drives gives 6TB data 4TB parity), so it would mostly be a matter of the math.
10 drives would fit internally on my current layout, so anything under 11 would be my best bet.
