While the specification maintains the physical footprint that has become ubiquitous in modern computing, the underlying electrical architecture has been fundamentally overhauled to support raw data transfer rates of 32 GT/s (gigatransfers per second) per lane, effectively doubling the bandwidth of the previous generation.
The M.2 specification continues to provide a family of form factors designed to replace older Mini Card and Half-Mini Card solutions with a more compact and scalable design.
