MyDigitalSSD ships the M2X in a small, brown box. Along with a picture of the enclosure, the sticker on the front advertises many of its key features including its support for NVMe PCIe SSDs, shock and crush-resistant aluminum design and the grooved heatsink that aides in heat dissipation. The sticker also lists the form factors it supports as well as the package contents.

Inside the box you'll find the M2X as well as a USB-C to A cable, USB-C to C cable, a thermal pad, mounting screws, a mini screwdriver and a piece of paper with some instructions. The thermal pad is packed inside the enclosure which is why you don't see it in the picture above.

Physical Features:

While not nearly as small as a USB flash drive, the M2X is compact and light enough to fit in your pocket or purse. The enclosure measures 99 x 42 x 13 mm and tips the scales at a mere 1.76 oz (50g) with an SSD in it. 

The M2X's casing is made almost entirely out of aluminum. This not only protects your drive against shock and vibration, it helps keep it cool thanks, in part, to the grooved fin heatsink on the base of the enclosure.

Along the left hand side of the M2X, you can see its USB 3.1 Gen 2 interface. In addition to offering data transfer speeds up to 10Gbps, the interface provides power for the enclosure. The small circle to the left of the USB interface is the M2X's power/activity indicator, which lights up white when the enclosure is powered on and blinks when data is being transferred.

Inside the enclosure, there is a small printed circuit board (PCB). On the top of the board, you'll find an M.2 slot as well as a series of holes that let you mount SSDs 80mm, 60mm, 42mm and 30mm in length. 

On the bottom of the board, there is a series of chips. Most notable is JMicron's JMS583 controller chip which acts as a bridge between the USB host and PCIe storage device. In addition to providing Type-C connectivity, the JMS583 supports the TRIM command and complies with the specifications for both the USB Mass Storage Class Bulk-Only Transport (BOT) and USB Attached SCSI Protocol (UASP).
