W800SHMQ 512GB SSD

The W800S W800SHMQ 512GB SSD is a SATA M.2 SSD. The manufacturer is not specified (Windows only reports "GenDisk") and also the markings on the SSD are not helpful. The naming could point to Transcend. We first found the SSD in the Walmart Gateway GWTN141 with the P/N W800SHMQ, SN08108W. Ith SSD is Made in China and FCC / CE approved. The speeds are limited by the SATA 3 interface.
