The M.2 2280 format of the Crucial MX300 525GB SSD is also featuring 3D TLC NAND, but comes with higher capacity packages. The same Marvell 88SS1074 quad-channel controller can be spotted on the PCB, along with a 512MB LPDDR3 RAM chip which acts as cache. The product does have thermal protection and thanks to the onboard capacitors it also sports power loss protection; thanks to the controller, MX300 also incorporates Dynamic Write Acceleration, Data Defense and RAIN technologies, AES 256-bit disk encryption but also DEVSLP power mode which saves power when installed on battery-powered devices.
