ZFS seems the most vigorous FS available in pfS, that's why I moved over from UFS to ZFS. The (re)install is a breeze, with a current config file at hand.
My APU2C4 has ECC and to me this and the ZFS FS seems max what I can do against sudden power surges, that being said, I would always use the "halt" command before I pull the power cord ;)
@bouke Kudos for pointing out the flaky mSATA issue link, didn't knew that.
