6^th cycle

h2benchw sequential read/write test

We decided to run the sequential h2benchw test and immediately switch to I/O loads three times in a row, so the drives would have to switch from maximum throughput to maximum I/O performance repeatedly. Then we ran three additional h2benchw tests to see if and when the flash SSDs returned to their initial performance levels.
