Transcend MTE112S M.2 2280 NVMe SSD, PCIe 3.0, 256GB–1TB

A full-length 2280 Gen3 card with 3D NAND and a five-year warranty, sold for straightforward laptop and desktop upgrades on boards that predate PCIe 4.0.

Retailer specifications put the 1TB board at 3.5mm thick, meaning it is double-sided. Slim laptops and M.2 sockets with a heat spreader already fitted often clear only a single-sided card, so measure before ordering; the Transcend MTE115S M.2 2280 NVMe SSD is 2.23mm single-sided.
