Interesting read, thanks for sharing.

It didn’t even occur to me that the file systems will need to change to fully take advantage of NVRAM. I wonder at what point the abstraction will stop leaking and require another higher layer to account for differences in performance. I’m sure the OS will need tuning, but applications might not unless they’re pretty bare metal.

One of the reasons why Apple's new file system APFS was developed was optimization for flash storage. HFS+ was designed with floppy and spinning disks in mind.
What notable changes did APFS implement to accommodate flash storage?
