SSD disk Transcend 256 GB M.2 PCI Express NVMe 400S

Transcend PCIe SSD 400S (M.2 42mm, 256 GB) is a compact NVMe drive designed to upgrade Ultrabooks, lightweight notebooks, tablets, and handheld gaming PCs. Built with high-quality 3D NAND flash and a PCIe Gen3x4 interface, the MTE400S offers faster data transfer than SATA SSDs while preserving low power consumption for ultra-thin devices.

Advantages

The SSD delivers sequential read speeds up to 2,000 MB/s and sequential write speeds up to 1,700 MB/s, plus up to 275,000 IOPS for 4K random read/write operations. Firmware optimizations such as SLC caching and LDPC ECC improve performance, storage reliability, and drive lifespan. Its 42 mm M.2 form factor is thin and lightweight, making installation in compact systems straightforward.

Suitable for

• Upgrading Ultrabooks and thin-and-light laptops
• Increasing storage and responsiveness in tablets
• Enhancing performance of handheld gaming PCs
• General productivity workloads and faster application load times
