> ZFS is rad. Typo: RAID

I'd bet that was intentional, because https://www.urbandictionary.com/define.php?term=Rad https://www.urbandictionary.com/define.php?term=Rad

Only 1/4 of data lost! Meaning still recoverable!

Redundant Array of Disks (cost not specified)

  I always thought it was Independent Disks, though how one disk could be dependent on another is beyond me. Perhaps the I is redundant?

    Looking it up I think you are right. I thought it was inexpensive.

Repeat after me: RAID is not a backup. Sounds like it was the backup which saved the day here, not the raid array.

  He didn't have a raid array on his laptop, that would have saved him as well, with not even a second worth of data lost. And he could use his system without replacing any drive and he would have had a much quicker recovery and could have used the system during rebuild. Now, raid on a laptop is mostly reserved to bigger units. And authors setup is awesome as well, but single drive failure is one of the most common issues (especially where you make use of snapshots) you need your backup and that is exactly what raid solves. So try to do both :)

      Missed that context, meant regarding the article.

  zfs send was used, so the failed zfs still had a hand in the positive outcome
