Transcend MTS425S 2TB M.2 2242 SATA III 6Gb/s Internal SSD
TS2TMTS425S
The Transcend MTS425S 2TB (TS2TMTS425S) is a high-capacity, compact M.2 2242 SATA SSD designed for ultrabooks, mini PCs, and embedded systems where space is limited. Built on the SATA III 6Gb/s interface, it delivers sequential speeds of up to 550 MB/s read and 500 MB/s write, offering a significant boost in responsiveness, boot times, and file transfers compared to traditional hard drives.
Designed with a 42mm (2242) form factor, it is ideal for slim and lightweight devices where standard 2280 SSDs cannot be installed. This makes it a perfect upgrade solution for compact laptops and specialised systems.
Built using 3D TLC NAND flash, the MTS425S ensures a balance of performance, durability, and efficiency. It also features SLC caching, LDPC ECC error correction, and advanced firmware optimisation, improving performance stability and extending the lifespan of the drive.
With support for TRIM, S.M.A.R.T monitoring, AES 256-bit encryption, and DevSleep low-power mode, the drive ensures strong data integrity, security, and energy efficiency.
Offering a high 720TB endurance rating and an MTTF of up to 2 million hours, the MTS425S is a reliable, long-term storage solution for both personal and professional use in compact systems.
