Re: So that's the end of RAIDs then
Nice advertisement for ZFS...except for one thing. It's NOT platform agnostic. Otherwise, it would work natively in Windows.
"An OpenZFS port of code to Windows is not likely in the foreseeable future. The OpenZFS launch discussion on Slashdot touches upon some of the issues."
The closest solution to this is to use another machine and network the drive. zfs-win only mounts the drive read-only. Oh, and I also read that its more robust data-protection features are memory-intensive.
In any event, I'm thinking of the more likely event of gradual deterioration (a sudden catastrophic drive failure is basically game over for anything short of paranoid redundancy, which is not usually the desired setup for a consumer). PAR files combined with strategic physical file allocation (arrange the physical files ext-style, shotgun-like) should increase the odds of a recovery in this scenario.
