Introduing Next Generation Form Factor (NGFF) SSD

3/11/2014
PAPS would like to introduce the latest technology in the SSD market to everyone. It is called: Next Generation Form Factor (NGFF) or M.2. The M.2 standard is led by Intel® and has been defined with the combined input from many players in the electronics industry. M.2 also supports SATA and PCIe interfaces. Generally speaking, M.2 is used to replace the mSATA interface on small devices.
PAPS has done some research and concluded that there are some advantages to consider whencomparing M.2 to mSATA. Users should consider the following:
1. Smaller Size
The dimensions of SSD with mSATA are 51mm x 30mm, with a one-side thickness of 4.85mm while NGFF is only 42mm x 22mm, with a one-side thickness of 2.75mm.  Even with a double-sided thickness of 3.85mm, NGFF SSD is still thinner than mSATA with its one-sided NAND. The reduced dimensions optimize the function of the SSD.
2. Bigger Capacity
Compared to mSATA SSD, NGFF SSD standardizes the width and length and adjusts its length to increase capacity. So far, five lengths have been discussed. They are: 20mm, 42mm, 60mm, 80mm and 110mm. Among them, 42mm, 60mm, and 80mm are most likely to eventually become the standard. The greater the length of the flash memory, the higher the capacity
3. Multiple Interface Types with Faster Transfer Rates
NGFF has two defined interfaces, Socket 2 and Socket 3. Socket 2 supports SSD, WWAN, and other non-storage devices with SATA and a PCI-Ex2 interface. Socket 3 is designed for high-performance storage which can support PCI-Ex4 with small dimensions and larger bandwidths of up to 4GB/S.
Also since NGFF SSD adopts PCI-Ex2, the maximum transmission speed reaches700MB/s and write speed is up to 550MB/s. Random read and write IOPS for 4K are up to 100K and 90K. Overall, compared to SATA interfaces supported by mSATA, NGFF support is more diverse, with more types of SATA interfaces supported and faster transfer rates.
Since the beginning of 2014, many SSD players in the industry have been introducing NGFF SSD products one after the other. Current SSD is designed with SATAIII 6Gb/s interface. With the new specification for NGFF to support PCI-e, NGFF SSD is expected to become the norm in high-end SSD market. PAPS will keep watching this developing technology trend. We plan to phase in NGFF support in the fourth quarter, 2014.
