If you are looking for SATA-based storage for a small device or application, then M.2 SATA and mSATA are two options that you may consider. Although they have similarities, they are not interchangeable, and one is not better than the other in every case. For engineers, understanding M.2 SATA vs. mSATA and weighing up how they can work for a specific design is the key to making the right choice. Here is a closer look at how these two small-size storage solutions compare.

mSATA

mSATA, or mini-SATA, is essentially the same as the full-sized SATA drive. The full-sized SATA format is 2.5 inches, which makes it too large for a number of different devices. mSATA was introduced for devices that require SATA-style storage, but with a smaller form factor.

mSATA comes in both SLC and MLC versions with capacities of up to 1TB. It is known for its lower power consumption and high level of reliability in industrial applications that operate in rugged conditions. Despite its benefits, newer designs are moving away from mSATA in favor of different form factors. However, it is still a reliable solution for the needs of industrial applications and is still found in a wide range of devices.

M.2 SATA

M.2 is a newer form factor, which was previously called Next Generation Form Factor, or NGFF. Not all M.2 flash storage devices utilize SATA—in some cases, they use PCI-Express. M.2 SATA is a faster alternative to mSATA. M.2 comes in a wide range of sizes, interfaces, and flash types, so it can easily be integrated into a wide range of applications. It can also be designed with custom sizing.

M.2 SATA uses the ACHI drivers that are the norm in today’s operating systems. This feature makes it likely that M.2 SATA will be easily compatible with future NAND designs.
