RE: Restoring Hive-Engine Full-Node: How I Fought MongoDB's WiredTiger Throttle and Won

Depending on the SSD, you can also tune the queue and block size to perform to its best.

NVMe's are better because of their RAM cache and controllers' further "atomic" stuff, but SAS enterprise cards' stuff does many more atomic commands, which, when used on SAS controllers, drops the latency of high IO/ps quite a lot. So, depends on what you have...

New BIG NVMe's are a different beast, I am still exploring... and they are almost like a computer! It's going to be a game on PCIe over those...
