Thanks. I was thinking that is is related to rotational delay too. But 68
TPS still look a bit slow for me.
On the another (slower) server with 4 SATA disks in RAID-10, I'm getting
~250 TPS, which is almost 4X of my new server.
And this is weird for me since, if I'm getting everything right — 4 disks
in RAID-10 should be only 2x faster than 2 disks in RAID-1
