Samsung Electronics has unveiled the 850 EVO M.2 and 850 EVO mSATA solid state drive (SSD) lineups. The 850 EVO M.2 and mSATA SSDs are new form factors of the 850 EVO SSD that launched in December 2014 and features Samsung's 3D V-NAND technology.

The M.2 and mSATA SSDs are only one-tenth the weight of a traditional 2.5-inch SSD, Samsung said.

In December, Samsung unveiled the 850 EVO featuring 3-bit 3D V-NAND technology, which 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.

The Samsung 850 EVO mSATA comes in 1TB, 500GB, 250GB and 120GB capacities and boasts the same read/write speeds as the 2.5-inch 850 EVO, with read speeds of up to 54MB/s and write speeds of up to 520MB/s.

The 850 EVO M.2 will be available in 500GB, 250GB and 120GB capacities, offering read speeds of up to 540 MB/s and write speeds of up to 500MB/s.
