Thanks for all the replies :) My mindset is split in two now... Some detail - I'm using 4 1-to-5 Sata Port multipliers connected to a 4-port SATA raid card. I only need reliability and size, as long as my performance is the equivalent of one drive, Im happy. Im assuming all the data used in the group is read once when re-creating a lost drive. Also assuming space consumed is 50%. So option 1 - Stay with the 2 x 10drive RaidZ2. My concern is the stress on the drives when one drive fails and the others go crazy (read-wise) to re-create the new drive. Is there no way to reduce this stress? Maybe limit the data rate, so its not quite so stressful, even though it will end up taking longer? (quite acceptable) [Available Space: 16TB, Redundancy Space: 4TB, Repair data read: 4.5TB] And option 2 - Add a 21st drive to one of the motherboard sata ports. And then go with 3 x 7drive RaidZ2. [Available Space: 15TB, Redundancy Space: 6TB, Repair data read: 3TB] Sadly, SSD's wont go too well in a PM based setup like mine. I may add it directly onto the MB if I can afford it. But again, performance is not a prioity. Any further thoughts and ideas are much appreciated.
