Thanks for sharing! I just setup a fs benchmark system and I'll run your fio command so we can compare results. I have a question about your fio args though. I think "--ioengine=sync" and "--iodepth=16" are incompatible, in the sense that iodepth will only be 1.
"Note that increasing iodepth beyond 1 will not affect synchronous ioengines"[1]
Is there a reason you used that ioengine as opposed to, for example, "libaio" with a "--direct=1" flag?
