Didn't know it's addressable volume seen by the OS. Was thinking it's just automatically handled space, a cache, where the content is decided by some advanced driver working with some statistics about...
yup, it is as you say, when set up that way. Although that caching mode is only supported on Windows. But for Linux, you have to turn it off in the bios, and then it shows up as normal nvme.
I did some test. The read speed is 900MB/s, write is 150MB/s. Nothing to write home about. Latency (ping) was 70µs! For comparison: SATA SSD had ping of 3ms. RAM has 7µs.
There may be some better optane drives out there. Mine is a little 16GB, consumer grade.
