Host managed SMR is similar to SSD in terms of what needs to be done.

- wtallis 7y agoThe latency difference means the two are suited for very different real-world workloads. But they're similar enough in the access patterns they prefer that the software work to make your IO fit those patterns can be shared between SMR and flash.
