Performance management 101 on AWS volumes:
1) The IO of a disks is proportional to the size of the volume. You need to get bigger volumes to get more performances. 3 io/GB
2) The high performance volumes (io1/PIOPS) are extortion. It's cheaper to pay for a bigger regular volume (gp2) that comes with a higher IO quota than to pay for the special high performance volume.
3) Each instances type has a disk performance cap. They are lower than you think.
4) Don't use t2 instances for anything that requires non negligible sustained IO.
P.S. Clearly the author is just discovering AWS.
