Samsung released the 850 EVO M.2 and 850 EVO mSATA solid state drive (SSD) lineups. Just one-tenth the weight of a traditional 2.5-inch SSD, the M.2 and mSATA SSDs are ideal for users looking to upgrade their desktop or ultrathin PCs with high-capacity, high-performance storage.
“By offering the 850 EVO in multiple form factors, Samsung is giving every PC user the opportunity to upgrade their device with the speed, reliability and endurance of 3D V-NAND,” said Unsoo Kim, Senior vice president of branded product marketing team, Samsung Electronics.
“There is growing demand for high-capacity SSDs and these new form factors will help drive further adoption of SSDs as well as expand Samsung’s leadership position in the consumer storage market.” In December, Samsung unveiled the 850 EVO featuring 3-bit 3D V-NAND technology, which greatly enhanced the everyday computing experience by overcoming the density limitations of conventional planar NAND architecture. 3D V-NAND stacks 32 cell layers vertically over one another, rather than decreasing cell dimensions to fit onto a fixed horizontal space, resulting in higher density and better performance with a smaller footprint. Now, with the M.2 and mSATA form factor SSDs, more consumers with desktops or ultrathin PCs can benefit from best-in-class performance and reliability of the 850 EVO and V-NAND technology.

Each drive manages large data transfers and complex multi-tasking operations using the Samsung TurboWrite technology. Featuring the TurboWrite technology, the 500GB and 1TB models offer random write speeds up to of 88K Input/Output Operations Per Second (IOPS), and random read speeds of up to 97K IOPS, meaning each drive is able to easily manage large data transfers and handle complex multi- tasking operations. Similar to the 2.5-inch 850 EVO, the M.2 and mSATA drives offer enhanced reliability with improved sustained performance, as well as AES 256-bit hardware-based encryption to ensure the safety and security of data. The Samsung M.2 and mSATA 850 EVO SSDs have a five-year limited warranty and an endurance rating of 150 total bytes written (TBW) for the 500GB and above capacities.
