Transcend 400S TS1TMTE400S 1 TB

A model from the compact M.2 SSD family featuring a PCIe Gen3 x4 (NVMe 1.3) interface, equipped with a DRAMless controller and 3D NAND memory. The drive is designed as a compact caseless device, size 2242. This design allows usage in dense configurations typical for ultra-compact laptops. Compatible with motherboards featuring a Socket M.2 M-key. The theoretical bandwidth of the interface is 4GB/s, but the actual speed is limited by the controller-memory link, with sequential read/write speeds reaching 2000/1700 MB/s.

The Transcend 400S TS1TMTE400S SSD is positioned as a mid-range product, intended for installation in devices where use of form factor 2280 models is not possible. It is designed for some compact laptop models by Lenovo, HP Book, and Dell, which use 2242 form factor SSDs as primary or additional storage. It can operate in miniPCs/all-in-one systems and be installed in desktop PCs if the motherboard has an M.2 slot supporting NVMe with the corresponding mounting hole. Equipped with a DRAMless controller with low power consumption, SLC caching, and improved error-correction algorithms. The stated TBW of 400 TB is sufficient for daily writing of 350GB of user data over 3 years.
