Having said that, we are comparing apples and oranges, because that commercial M.2 drive will have its own architecture, its own flash controller and so. For example, the NVMe specification lays out a priority scheme for requests that the M.2 drives can use, and that scheme is pretty nice, but it only has two true priority levels. Our drive supports six. We can hook up a drive with only two priority levels, definitely, but our custom I/O unit has to arbitrate the extra priorities rather than the M.2 drive's flash controller, and so the M.2 drive needs a little extra speed to take care of issues arising from the different approach. That commercial drive also needs to physically fit inside of the bay we created for PlayStation 5 for M.2 drives.
