New NVMe SSD not seen by OSes

@tophneal, yes, 80mm are the most common length. Followed by 42mm, then 100mm.

Western Digital does make a M.2 NVMe line that has the same capacities in 30mm, 42mm & 80mm lengths.
These also have published power specifications, (reasonably good), unlike other brands.

Hi Arwen!
I tried to upgrade my T440s with this SSD: WD SN520 NVMe 512 GB M.2 2242 PCI Express 3.0 x2. The motherboard do not recognize the SSD at all. It is recognize the SanDisk 64GB with windows 10. I tried to put the brand new WD SSD on an enclosuer and connect to 2 other pcs, and still not detected. I contacted the seller and he says it must works, so is it the quality of the WD SSD or it might be something else?
