Transcend 256GB | PCIe M.2 SSD 300S | M.2 2230 | NVMe PCIe Gen3 x4 | 3D NAND Flash | up to 2,000/950 MB/s | 5 Yrs. Warranty

The Transcend MTE300S 256GB is a compact NVMe internal solid-state drive designed for systems that require the smaller M.2 2230 form factor. Measuring just 22 mm wide and 30 mm long, this drive fits into space-constrained devices such as ultrabooks, mini-PCs, and certain gaming handhelds that cannot accommodate the more common 2280-length modules. Built on the PCIe Gen 3.0 x4 interface with NVMe protocol support, the MTE300S delivers sequential read speeds of up to 2,000 MB/s and sequential write speeds of up to 950 MB/s, representing a substantial performance improvement over traditional SATA-based M.2 drives. The drive uses 3D NAND flash memory, which stacks memory cells vertically to achieve higher density within a small physical footprint while maintaining reliable read and write endurance over time. For buyers looking to upgrade or replace storage in a Surface Pro, Lenovo ThinkPad with a 2230 slot, or a Steam Deck, the 2230 form factor makes this one of the few NVMe options designed specifically for that slot size. The 256 GB capacity provides a practical base tier for operating system installations, frequently used applications, and essential files. Transcend backs the MTE300S with a five-year limited warranty, reflecting confidence in the drive's long-term reliability under typical consumer workloads.
