MyDigitalSSD M2X – Sub $40 M.2 PCIe NVMe Portable USB Drive Enclosure

Have you wanted to make a portable portable SSD with a USB enclosure that holds an NVMe SSD? The MyDigitalSSD M2X Portable SSD enclosure runs $39.99 shipped and allows you to do just that. You take any NVMe PCIe2242/2260/2280 SSD and pop into into the M2X enclosure and you’ll have created a peppy little portable SSD (99mm x 42mm x 13mm) that can travel with you.

The enclosure works with single-sided and double-sided NVMe drives that are up to 2TB. The MyDigitalSSD M2X enclosure uses a JMicron JMS583 USB 3.1 Gen 2 to PCIe Gen3 x2  bridge controller that allows for speeds of up to 1,000 MB/s read and 1,000 MB/s write. A grooved fin heatsink design reduces temperatures to keep the SSD inside from thermal throttling as much as it can.

MyDigitalSSD said that to hit 1GB/s sequential speeds that you’ll have to have a cutting edge system, but that it is possible to hit those numbers and provided CrystalDiskMark benchmark results using a MyDigitalSSD SBX 1TB drive ($219.99 shipped) to back those claims up. They hit 948 MB/s read and 959 MB/s write with that particular drive on a system with the ASUS ThunderboltEX 3 expansion card ($69 shipped), which is pretty impressive for a $39 enclosure.  Our contact over at MyDigitalSSD said that those speeds should also be achievable on any USB 3.1 Gen 2 port. Hopefully we’ll be able to review the M2X here shortly and bring you our own results on a number of different ports.

The MyDigitalSSD M2X along with the MyDigitalSSD SBX 1TB drive come to a grand total of $259.98. The SanDisk 1TB Extreme Portable SSD runs $274.89 and tops out at 550 MB/s read and write speeds since it uses a SATA SSD inside. The solution that MyDigitalSSD came up with offers a pretty good bang for the buck compared to what is on the market today.

The MyDigitalSSD M2X features a USB-C connector on the housing, but 12-inch USB-C to USB A and  USB-C to USB-C cables are included. No drivers are required and it happens to be fully bus-powered. A 1-year warranty covers the MyDigitalSSD M2X and it is available now for those that want to create their own low-cost portable SSD.
