Interesting, so if it has EPO protection so in the event of a power off occurring mid flush, you can effectively do away with a BBU write cache for your drives.
It feels like a SLOG mixed with an ARC for ZFS storage mediums.
During an EPO, there is a high possibility of physical platter/head damage. How will NAND fix that? Or maybe recovery software can re-locate data to non-damaged parts of the platters. This is a good thing.
Probably demonstrated with SLC/MLC/TLC and then later to be switched out for PLC. Gotta save those 2 cents.
IIRC if hard drives lose power then can use the spinning platter as an energy store, and the motor as a generator to power itself long enough to safe the drive. That must have been about 25 years ago they started doing that? Hot swap drives wouldn't work very well if this wasn't a completely solved issue.
