Your English is fine. Not perfect (no one ever is), but I know plenty of
native speakers who speak it worse than you.

In my opinion btrfs has a bad rap partially because of the RAID5/6
situation, but also because for a long time it was marked as
experimental, and there are some situations where data loss has occured
(I'm guessing because of RAID5/6). But as long as you avoid RAID5/6 and
stick to RAID1/10, you should be fine.

Ignoring Raid5/6 and similar, I don't know what features btrfs is
lacking that make ZFS more attractive. Btrfs does have *nice* features
that ZFS currently lacks, like adding and removing disks to the array
on-the-fly and intelligent data balancing while the array is mounted.

Btrfs's killer feature, imo, is its Copy-On-Write features, which you
can read about on the Arch Wiki:


Btrfs also corrects read errors on-the-fly, something ZFS doesn't do,
but only if you are using a RAID with some level of redundancy.
