Has there been any btrfs discussion off the list (I haven't seen any SMR/shingled mails in the archive since 2016 or so) regarding the news that WD's Red drives are actually SMR? I'm using these reds in my btrfs setup (which is 2-3 drives in RAID1 configuration, not parity based RAIDs.) I had noticed that adding a new drive took a long time, but other than than, I haven't had any issues that I know of. They've lasted quite a long time, although I think my NAS would be considered more of a cold storage/archival. Photos and Videos. Is btrfs raid1 going to be the sweet spot on these drives? If I start swapping these out -- is there a recommended low power drive? I'd buy the red pro's, but they spin faster and produce more heat and noise. Rich
