80% Random Read Mixed Workload
The mixed-data random write test tells nearly the same story, though the group of drives in the middle is separated by a little more variation. Mushkin's 512GB Reactor is in the lower half, along with Crucial's BX100. The 850 Pro again demonstrates the best performance at QD2 and QD4, and when it comes to low-cost storage, Samsung's 850 EVO trails just behind the 850 Pro. Samsung's caching scheme, TurboWrite, really helps the TLC-based 850 EVO in this workload.
