Does this appear to the OS just like a flash drive would appear? Then I could use it for ZFS intent log or bcache or whatever, which is good. At 32GB it's not really big enough to be useful for anything else.
However, Intel's specs say this is only supported on Kaby Lake processors and chipsets - why is that? Surely NVMe is NVMe? Is this actually a proprietary interface?
The potential benefits over SSD might be:
- longer durability
- not being tied to a block-erase cycle for writes
The latter could make a big difference. I have seen SSDs where the write throughput has dropped from 200MB/sec to 10MB/sec after a few minutes of sequential writes, because of thermal throttling from all of those erase cycles.
