The existing standard for solid state drives (SSDs) is the mSATA standard. However, the existing mSATA standard has too many restrictions. Only 4 to 5 flash memories can be placed on the circuit board (PCB), resulting in capacity. Restricted, if the capacity of the solid state drive exceeds the limit, the existing mSATA standard will not be applicable. Therefore, the new standard for solid-state hard drives comes into being, namely the NGFF (Next Generation Form Factor) standard (also known as the M.2 standard), which can lay flash memory chips on both sides of the board, compared to The mSATA standard has the advantages of smaller size, higher capacity, and reduced cost.

In order to comply with the new standard such as NGFF, connector manufacturers have also developed NGFF card edge connectors of corresponding specifications.
