Maybe your fio is hitting RAM? fio for 905p / p5800x is usually low micros. Order of magnitude faster than other nvme but not as fast as RAM.

- jleahy 3y agoEven hitting RAM takes the best part of 100ns. They probably mean 5-10us given the ‘6x faster’ thing.
- choppaface 3y agodo you have your fio benchmark / args handy? i would love to get sub-micro out of optane, even if it's only on paper
- NavinF 3y ago50ns is typical with overclocked desktop RAM
- pbalcer 3y agoit's possible to get <1us with Optane PMem (the dimms) in fio, you just need to use the memory-specific engines so that it avoids the fs/block layer.
