After reading about bitrot and feeling guilty for storing my most valuable data on cheap drives (although with backups!) I've been thinking about moving to something more resilient.
Another thing you should consider is the possibility of bitrot inside your PC. A while ago I had a damaged DIMM in my PC and it corrupted the BTRFS filesystem twice before I realised the cause. As BTRFS and ZFS are more complex than most filesystems there are more ways that things can go wrong in the face of sustained random corruption. If you use the "resilver" option in ZFS (to read and write-back data to cover the case where magnetic fields fail over time) and have memory errors it can write back bad data. http://www.dell.com/au/business/p/poweredge-t110-2/pd The Dell PowerEdge T110 is a cheap system that takes ECC RAM. It's worth considering for a home ZFS or BTRFS file server, I have one running a BTRFS RAID-1 array on 2*3TB disks. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
