"Due to potential legal incompatibilities between the CDDL and GPL, despite both being OSI-approved free software licenses which comply with DFSG, ZFS development is not supported by the Linux kernel"
@mcc @petrillic @whitequark btrfs will allow you multiple copies of your data and metadata on a single disk.
It might protect against some disk issues, but probably not that many. SSDs will just stop working altogether on controller or dram failure and lose all of the disk at once.
I hope you are aware that SSDs are not recommended to be kept unpowered - the 10 year data retention relies on scrubbing that happens only when the power is on.
