Crucial MX300 Solid State Drive Overview
The Crucial MX300 solid state drive comes in the typical 2.5-inch form factor we are used to. The drive itself has a metal chassis with a “Crucial MX” sticker on the top.
Flipping over to the back there is another sticker that has all of your model / product numbers on it. There are four mounting holes on the bottom of the drive. We can also see that Crucial has gone with a screwless design for the chassis, which makes it a little tricky to open up.
The MX300 is 7mm thick, which is pretty much standard now for 2.5-inch solid state drives. Crucial does include a 7mm to 9.5mm adapter if you need it. There are also two mounting holes on each side of the drive.
Like all 2.5-inch SATA solid state drives you have SATA power and data connections on the end of the drive.
As I said the drive is a little tricky to get open so we will not be opening it. We will let you know what is inside though. The drive is powered by the Marvell 88SS1074 controller. This 4-channel controller features ONFI 3/Toggle 2 support at 400MT/s, 256 AES encryption, and Low power support with integrated DEVSLP (Device Sleep). There are eight total NAND packages, these are of course Micron 3D TLC NAND packages. Each package has two 48GB (384Gb) dies, so you have a total raw capacity of 768GB. There is also a 512MB LPDDR3 cache chip.
