Compared with mSATA SSD,NGFF Have smaller size,save more space for Ultrabook,mainly used for Notebook,Tablet,Ultrabook,etc. Compared with SATA III and mini PCI-e Interface,NGFF  Adopt 4 x PCI-e Interface for transfer,Speed much more higher.

Position 1

mSATA SSD Size is 51mm x 30mm,single thickness is up to 4.85mm.

NGFF Size is only 42mm x 22mm,Single size arrange NANA FLASH Thickness is only 2.75mm,Dual Thickness is 3.85mm,Volume reduced highly,but Performance better and SSD Optimization .

Position 2

Compared with mSATA SSD,NGFF SSD can Increase capacity by increasing length and have same thickness and width,only Length Difference. NGFF have 5 Lengths:20mm,42mm,60mm,80mm and 120mm,but 42mm,60mm and 80mm Version will be most likely to become Ultimate Standard.Longer length represent that Limited Space can be filled with more Flashes,and capacity become bigger as well.

Position 3

NGFF Have two Interfaces:Socket 3 and Socket 4,former one support SATA,PCI-e x 2 SSD,WWAN and other Storage Devices,but Socket 4 is customized for High Performance Storage SSD,support PCI-e X 4 interface,speed up to 4GB/s.

Compared with mSATA Supporting SATA Interface,NGFF Have more Choices,and higher Theoretical Transmission speed.

Position 4

Compared with mSATA,NGFF transfer faster,Adopt PCI-Express x 2 transfer mode, Max Sustained Read Speed up to 700MB/s,with Write Speed up to 550MB/s,4K Random Read and Write up to 100K and 90K.
