I've read about ECC/non-ECC and RAID != backup and already decided on a solution - I wanted some indication of the stability of the ZFS features themselves. My question arose when I read that "dedup=fletcher4,verify" was causing problems [1] and was removed. I was looking for indications whether choosing "checksum=sha256, compression=on, dedup=verify" in itself was asking for trouble.

Because photos tend to be already compressed, and I have only ~5% duplicates, I will probably only change "checksum=sha256" from its default. Other than CPU time, is there any other reason I may want to stick with the default of "checksum=on" (fletcher4)?
