-Another cons of ZFS is that it lacks a fast RAID implementation in assembler.
-It only has a C implementation, that is from two to four times slower than SnapRAID/Btrfs.
-
ZFS also uses a sub-optimal RAID-Z3 algorithm, that requires double computations than the equivalent SnapRAID's z-parity.
-
-Instead, both SnapRAID and Btrfs use top-notch assembler implementations to compute the RAID parity,
-always using the best known RAID algorithm and implementation.
