Quick maths ... 7 spindles, 2TB disks, raid 5. I make that 12TB storage.

6 spindles, 3TB disks, raid 6. I make that 12TB storage :-)

If disks are cheap you could upgrade the disks in the nas, then convert to raid 6 :-)

Dunno if you want to do that, though, I've just bought two 3TB disks, so I make the cost of your upgrade about £300 (Seagate Barracuda disks).

Cheers,
Wol

Indeed. But the actual storage is about 11TB. Doing a full convert would be a pain in the butt. :D It helps that I have the backup array though. So I could. I don't currently have enough 3TB disks to do that however. the backup array has 5 3TB disks. so it wouldn't actually be too expensive to do, just one more (or two, cause why not?) disk(s). If I do, I'll be waiting for a big sale on the 3TB disks. It's just not a huge priority for me at the moment. I have more than enough storage and enough protection at the moment to last quite a long time.
