A drive can fail day 1, day 90 or day 10,000 -- but in the end, they all fail eventually. You need multiple copies of data on multiple drives, or perhaps you'll get by with Russell's idea of using RAID1 on BTRFS, but I wouldn't trust that solution and it is limited to being used with Linux ... good or bad. You can use ext4 anywhere, even on Windows with the right drivers.
I wouldn't trust anything that only involves a single disk when given a choice. But when you do have to rely on a single disk using RAID-1 on that disk will significantly decrease the probability of data loss. This is why ZFS has the copies= option. As we are talking about replacing a ReiserFS filesystem support for Windows isn't a concern. A more significant issue is that a BTRFS filesystem created on Debian/Jessie can't be read with a kernel from Debian/Wheezy. But if you are concerned with hard read errors not data corruption then you could use Linux Software RAID-1 on a single disk. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
