Transcend MTE245S NVMe M.2 2280 SSD with Graphene Heatsink, PCIe 4.0, 250GB–4TB

Card and graphene heat spreader together measure 2.42mm, and the board is populated on one side only. That is the combination thin notebooks and console expansion bays need, where a finned aluminium block simply will not close.

It runs DRAM-less, borrowing host memory for its mapping tables, so continuous large writes favour the DRAM-cached Transcend NVMe PCIe Gen4 x4 M.2 SSD Solid State Drive. The 3,200MB/s figure in the old listing belongs to the smallest capacity.
