Crucial MX300 M.2 525GB SSD Review

Storage/SSD by stefan @ 2016-12-21

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.

A Closer Look Contd.

By removing the protective sticker, we will uncover two 3D NAND TLC packages, a controller but also a buffer RAM IC; the NAND TLC ICs are of higher density versus MX300 2.5’’ format, since there we did have a total of four:

The two NAND Flash packages do have different capacities: one is 384GB, while the other 144GB

Regarding the controller, it is the same as before; we’ve got a Marvell 88SS1074 which features four channels as well as encryption support, SLC caching, LDPC (low density parity check) and can function along with 15nm SLC/MLC/TLC NAND but also 3D NAND:

The cache RAM sports the F4416ACBH-DD-F code name, comes in the LPDDR3 format with a capacity of 512MB and it operates at 1600MHz:

The PCB also houses a MSP430 G2353 MCU:

The M.2 gold-plated interface contacts can be also observed near the memory cache:
