I'm not sure it could be implemented in the reader for SD cards, since the SD cards usually do internal wear levelling. (And I don't think the levelling is in the spec. I mean, it's not a standardised algorithm, but varies between manufacturers.) > - p 26 avoid btrfs/f2fs if OS can be reset by unscheduled power > outage or hardware watchdog, unless you have a BBU or > similar. ext4 survives many more outages than btrfs/f2fs. Really? You had them suggesting using nojournal for ext4 just above, but now saying btrfs is less resilient. That's a rather surprising outcome. I would have thought btrfs's copy-on-write system would come out as much safer than ext4 w/out a journal! _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
