hi,
from the reading I've done there is that first conclusion -
it may different a lot with each FS - people theorize. I
wonder if anybody put them into practice.
I wondered if btrfs/xfs was any good, etx4 in current
kernels does not support "packed_meta_blocks" yet. Some
hands-on experience.
thanks

Did not try and will not try.
All published reports indicate that write performance is erratic (and quite
reduced
compared to conventional storage), making them unsuitable to our main
application
of recording experiment data in near-real time.
These SMR disks are marketed by Seagate as "archive" media, but because they
are very new there is no failure statistics, and the failure modes are not well
understood (if a spot of disk platter goes bad, do I lose just a few sectors,
like
on normal disks, or do I lose everything, like on a self-bricked SSD?). So does
the reduces cost compensate for the added risk of data loss?
You can also read the reviews at newegg and elsewhere.
K.O.
P.S. FUD check:
Fear - check,
Uncertainty - check,
Deception - hopefully not.
