Industrial M.2 SSD Products
M.2 (formerly known as NGFF, the Next Generation Form Factor) was first introduced in 2013 and intended to be a replacement for the mSATA standard as a computer storage medium. M.2 is a very flexible form factor, with a variety of physical sizes, interfaces and flash types to adapt to a wide range of storage applications.
Delkin Industrial M.2 is a caseless Solid State Drive solution with either SATA 3 or PCIe interface. Industrial M.2 can be built with SLC, pSLC or MLC, and are available in multiple sizes – with 2242 and 2280 being the most popular.
The Delkin Industrial M.2 SSD delivers outstanding performance in a small, industry standard form factor and includes many features to improve flash management and SMART data retrieval. The design optimizes data retention and flash endurance. Sequential Read and Write speeds up to 540MB/s can be achieved and reliability up to 10 DWPD.
Industrial Grade M.2 or Rugged M.2 usually refers to SLC based products that have higher endurance, higher temperature range, more longevity and are built using a controlled BOM and life cycle management plan. However, depending on the requirements of the application, lower cost alternative flash technology can be a viable option, such as Industrial MLC M.2 or Industrial pSLC M.2.
Different Physical Form Factors
An M.2 2280 is 22mm wide and 80mm long. Common lengths include 22mmx30mm (M.2 2230), 22mmx42mm (M.2 2242), 22mmx60mm (M.2 2260) and 22mmx110mm (M.2 22110). Typically host size constraints will dictate which Industrial M.2 is the best choice. Custom sizes are also available.
The 75 position edge connector on an Industrial M.2 provides flexibility for keying to indicate the type of interface , but only 2 are utilized industry wide at the moment. “B” key, “M” key, and “B & M” key edge connectors on Industrial M.2 cards are a notch on the connector edge which determines the correct Industrial M.2 interface, either SATA or PCIe, and if PCIe, 2 or 4 lanes. Other keying positions on the connector are also available for future use.
Industrial M.2 products support either SATA or PCIe interface, but not both at the same time – as the controller on the SSD supports only one interface protocol. System board sockets are built to support either standard, or both. Some Industrial PC system boards can have separate sockets for SATA, PCIe and some support both, even on the same board.
Industrial M.2 is a Futureproof Solution
While SATA-based Industrial M.2 SSD’s utilize the AHCI drivers built into most operating systems today and originally designed around HDD’s, Industrial M.2 PCIe SSD’s will use the NVMe (Non-Volatile Memory Express) host interface designed from the ground up to natively use todays NAND flash components and perhaps those new NAND designs coming in the future. NVMe may improve speeds up to 6X faster than today’s SATA 3 interface.
As the Industrial M.2 market continues to develop, Delkin is expanding its product offering to meet the needs of our customers. If you have any requirements for Industrial or Rugged M.2, please contact Delkin.
