MyDigitalSSD Introduces M2X External USB Enclosure for NVMe, M.2 SSDs

MyDigitalSSD is out with a relatively ingenious solution for users looking to get the best portable, external SSD performance available. Their new M2X external M.2 enclosure will allow users to create an external storage solution via a DIY kit. The M2X is built on JMicron's JMS583 USB 3.1 Gen 2 to PCIe 3.1 x2 bridge chip (meaning that a PCIe 2x NVMe will be sufficient in maxing out available performance), will only be limited by USB 3.1 Gen 2's 1GB/s throughput. The DIY assembly packs a thermal pad and the enclosure, as well as USB Type-C and Type-A cables, and will be available from Amazon for $39.99 or through MyDigitalDiscount for $36.14.

I'm guessing you have a faster external enclosure?

Yeah. 1GB/s it's not fast enough for an USB drive.... /facepalm

When USB3.1 Gen 1 is capable of 5GBps and Gen 2 10GBps, then 1GBps seems insufficient.
Methinks a typo occurred in the writeup and it is meant to be 10GBps, not 1GBps.

Thanks Captain obvious for the detailed explanation.
My own typo has been corrected now, care to explain now how the O.P. is correct and I am wrong?

USB 3.1 Gen 2 is 10 gigabits per second Gb/s. The OP says USB 3.1 Gen 2 is 1 gigabyte per second (GB/s), which comes out to 8Gb/s, so it is a little off there... should be 1.25GB/s.

Dude, 1GB/s = 8Gb/s, so in theory an SSD drive can go a little faster than that considering the USB overhead is usually ~10%

Well, if you think that this USB drive, or any USB3.1 G2 will be anywhere close to 1.25GB/s, you're mistaking... 1GB/s is much more realistic. I mean, we are talking about JMicron here...

You are wrong because USB3.1 Gen 1 is not capable of 5GBps, it is capable of 5Gbps, or 0.625GBps. And USB3.1 Gen 2 is not capable of 10GBps it is capable of 10Gbps, or 1.25GBps.

The typo is your's, the original news story is correct.
