It did not take long for Samsung to release two new form factors of their EVO series, the mSATA and the M.2. While the mSATA version was expected, the M.2 was a pleasant surprise since that format is favored over the mSATA.

There will be no new features nor ground breaking innovations, both drives are built with the same components as the 2.5in version but housed on a smaller PCB. What it means is, expect the same great performance as the 2.5in version but with a smaller footprint.

The mSATA version is available in 120GB, 250GB, 500GB and 1TB (1000GB) while the M.2. form factor ranges from 120GB, 250GB and 500GB. 5 years limited warranty is now the norm for the EVO line. Only the PRO version offers a 10 years limited warranty.
