I'm surprised Backblaze doesn't use host-managed SMR. I would expect that they'd already write data sequentially for speed and have different storage tiers (for "hot" data likely to be changed/deleted soon vs. data expected to stay for a long time). At least for large files in the cold tier SMR would make a lot of sense.
