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.
I guess because in some ways its so old school. (It saved money back then too.) Back in the "Home Computer" days card-edge connectors were used for expansion connections (on one side of the connection.) Retro consoles used it too with game carts. The PC used it then, and even still today, for expansion AND adding graphics. Back in the day Floppy drives, primarily 5.25" and larger used such a connection for data (and a molex for power.)
If that patent ever gets challenged, I dunno if it will hold-up because of all of that. In Modern storage though, the connector is, currently, unique though.
