Transcend 512GB | PCIe M.2 SSD 400S | 42mm | MTE400S | 3D NAND Flash | NVMe PCIe Gen3 x4 | up to 2,000/1,100 MB/s | 100 TBW | 5 Yrs. Warranty

The Transcend MTE400S 512GB (model TS512GMTE400S) is a compact NVMe solid-state drive built for systems that demand fast, reliable internal storage without the bulk of a full-length M.2 module. Housed in the M.2 2242 form factor — measuring just 42 mm in length — this drive fits slim laptops, mini PCs, and embedded systems where a standard 2280 card simply will not seat. Connecting over a PCIe Gen3 x4 interface using the NVMe protocol, the MTE400S delivers sequential read speeds of up to 2,000 MB/s, making application launches, file transfers, and OS boot times noticeably quicker compared with SATA-based alternatives. Sequential write performance reaches up to 900 MB/s, as confirmed by the source attributes. Storage reliability is underpinned by 3D NAND flash technology, which stacks memory cells vertically to achieve greater density and improved endurance relative to planar NAND. The drive carries a rated Total Bytes Written (TBW) figure of 100 TBW, indicating the endurance threshold Transcend supports under its warranty terms. Transcend backs the MTE400S with a five-year warranty, giving buyers long-term assurance on the investment. Data integrity features include S.M.A.R.T. monitoring and advanced garbage collection, both listed in the source description. These technologies help the drive maintain consistent performance over time and give system administrators early warning of potential drive health issues.
