Single is default for data. Metadata (and system) will normally default to dup on a single device, raid1 on multi-device, EXCEPT on detected SSDs, where it defaults to single as well, because the firmware on some ssds will dedup it in any case. If you know your ssd isn't one of the deduping ones (as I do, here), you can of course overrule that by specifying modes at mkfs.btrfs time. -- Duncan - List replies preferred. No HTML msgs.
