In addition to the normal run results, we wanted to see what we would get out of the BX300 once we enabled Crucial’s Momentum Cache. By the looks of the results below, there are definitely performance gains to be had.

Crystal Disk Mark

Crucial BX300 CDM Momentum Cache

In Crystal Disk Mark sequential performance multiplies just as the 4K random results do.

Anvil Storage Utilities

PCMark 8

Crucial BX300 PCMark 8 Momentum Cache
