I haven’t noticed anyone else bring it up, but you mentioned in passing the possibility of using a RAID 0. I’d avoid that except in very specific circumstances. They’re potentially fine for a scratch disk type of scenario, but if any member of the array fails, the whole array is toast. The chances of a failure increases with was each disk added, so a RAID 0 is less reliable than a single disk. I definitely wouldn’t want to trust my family’s photos to it.
