Transcend's SATA III 6Gb/s M.2 SSD 425S comes with a small form factor and high-quality 3D NAND flash, upgrading your Ultrabooks and laptops in a snap. The SSD is designed with multiple firmware optimisation technologies like SLC caching and LDPC ECC mechanism, which enhance the storage reliability and prolong the drive lifespan. A great difference can be made with a small upgrade.

Unparalleled Performance

Featuring the M.2 standard (42mm), the mainstream SATA III 6Gb/s interface and a powerful controller, Transcend's M.2 SSD 425S reaches incredible read and write speeds of up to 550MB/s and 500MB/s, providing 1.5 times faster boot time than conventional hard drives.

Designed for Slim Devices

The height of the M.2 SSD 425S is only 42mm, making it ideal for Ultrabooks and lightweight notebooks. Thinner and lighter than normal hard drives, the M.2 SSD 425S gives your computer a much needed boost while saving space!
