Crucial's MX300 M.2 SSD ships in a simple clamshell similar to what memory modules come packed in. The sticker on top shows the model, capacity and form factor of the drive. Inside the packaging, you'll find the drive, a bag containing a couple of mounting screws and a small piece of paper with a software activation key for Acronis True Image HD.

Physical Features:
The MX300 M.2 uses the 2280 form factor for M.2 (NGFF) SSDs. It measures about 80 x 22 x 2 mm and weighs in at a mere 9g. The drive is also equipped with a B+M edge connector which supports data transfer rates up to 6 Gb/s.
Like the 2.5-inch version of the MX300, the MX300 M.2 uses Marvell's 88SS1074B1 controller. Manufactured using an advanced 28nm CMOS process, the controller features support for 15nm TLC/MLC/SLC and 3D NAND. The 88SS1074B1 also offers low power support with integrated DEVSLP (Device Sleep) as well as Marvell’s third generation NANDEdge error-correcting, low-density parity check (LDPC) technology for superior endurance and reliability.
For the 525GB version of the MX300 M.2, Crucial opted to use Micron's 384Gb 3D TLC NAND flash. Looking at the picture above, you can see that there are two NAND flash packages (384GB and 144GB) on top of the PCB. The drive also has a 500MB Micron LPDDR3 memory chip that is used for caching as well as a number of ceramic capacitors that are part of its power-loss protection.
