4KB Random Write Steady State Performance
The first image that shows the preconditioning phase is all but useless with this many drives, particularly when they all have such a large spread between high and low performance.
The second image offers a clearer look at what the drives do once they're in steady state. We see there is more of a relationship between capacity and low steady state performance than there is the type of flash used. The TLC burst increases are spread further out than the spikes with MLC.
