Hi, all

I make android code on ubuntu 18.04 server. the default IO scheduler is cfq.and there are 3 IO scheduler: 1: noop 2:deadline 3:cfq

My server is Dell 730 /dell 740. raid adapter is H730p mini,

os disk is raid 1 with two 600GB 1.5k sas disk .

data disk is raid0 with four ssd disk.

work disk is raid50 with six 1.8TB 1.0K sas disk. (my android code is under raid0 disk or raid50 disk. not under the os disk.)
