m.2 2280

m.2 2280 is the most popular internal mounted computer memory expansion card widely used in the market. Comparing with mSATA card, its size is much smaller therefore providing more flexibility in all kinds of solid-state-drive applications. For small products like ultrabook, slim notebook and tablet, m.2 2280 is the ideal selection. The former name of m.2 is “Next-Generation Form Factor” or NGFF.

Many users of SSDs get confuse with the terms form factor and interface bus. Therefore, it is important we highlight them here again. The name m.2 or mSATA referring to the product form factor. We also need to know what kind of interface being used at each SSD. SATA interface and PCIe interface are two different buses with SATA interface having a limit of bandwidth for SATA III at 6Gbps. For PCIe interface, depending on whether it is 2 lanes or 4 lanes, with 4 lanes going up to 30Gbps.

It can be used to replace mSATA and mini PCI Express interface card. By shrinking the form factor, m.2 2280 become smaller and faster than mSATA interface card. Comparing with mSATA which has a higher speed of SATA 3.0 6Gbps, m.2 offer even faster speed than this. The thickness of m.2 is only 3.5mm and it is more energy efficiency (lower power consumption and longer battery life).

m.2 2280 module card is rectangular in shape, with an edge connector on one side and has a width of 22mm and length of 80mm. It is installed into a mating connector provided by the host’s circuit board. The four digit m.2 form factor designation are: (first 2 digit state the device’s width in mm, and the second set of 2 number tell you how long it is, also in mm).

There are more than one kind of m.2 connector and different type of interface, leading to various sizes of m.2 card offering. You need to pay attention to the physical connector on the card. Each card has different cutouts at the bottom and expose different pins. Different connectors lead to various types of “module key”. Each key exposes a different set of interfaces to each card.

For m.2 2280, there are 2 types of module keys (Key B and Key M). Key B suitable for interfaces of PCIe x2, SATA, USB 2.0, USB 3.0, audio, PCM, IUM, SSIC and I2C and this key is commonly used in SATA and PCIe x2 SSDs. Key M is suitable for interfaces of PCIe x4 and SATA and widely used in PCIe x4 SSDs.

Newer motherboards are having the PCI Express bus interface, PCIe 2.0 x4 with a throughput ceiling higher than SATA 3.0’s. Newest technology is adopting PCIe 3.0 using NVMe (Non-Volatile Memory Express) for heavy and deep workload. It is important for you to make sure the motherboard you are using is able to support PCIe x4 when selecting the suitable m.2 card.

Different PCIe technology offering various speed running:

  • PCIe Gen 2 x2 lanes can run speed up to 1000MB/s
  • PCIe Gen 2 x4 lanes can run speed up to 2000MB/s
  • PCIe Gen 3 x4 lanes can run speed up to 4000MB/s

We just launched new m.2 2280 with 1TB storage capacity. This is from UD info, famously used in the market which require high reliability, good tracking record and well service support. By introducing this 1TB model, UD info can support small form-factor embedded system to implement higher capacity internal storage.

Features of this 1TB m.2 2280 SSD card:

  • support SATA III 6Gbps speed
  • using MLC Toshiba NAND memory chips
  • temperature support from 0 to +70degC
  • performance read up to 520MB/s and write up to 500MB/s

m.2 SATA SSDs use the same controller currently available at typical 2.5 SATA SSDs, whereas m.2 PCIe SSDs use a controller specifically designed to support PCIe protocol.

If the host system does not support PCIe protocol, when you insert the m.2 PCIe SSD inside the socket it will not work because the BIOS is not able to detect the card. Similarly, if you instal the m.2 SATA SSD into a socket which support m.2 PCIe SSD, your card will not able to use. Make sure your motherboard is able to support PCIe x4 speed, before you buy the PCIe x4 m.2 SSD, otherwise the card only function as PCIe x2 speed. All the m.2 SSDs are not hot-pluggable, it means you need to power off the system when you install or remove the m.2 SSDs.

Future interface is Non-Volatile Memory Express (NVMe) and its expected performance will be 4~6 times greater than existing SATA 3.0 standard and to be name as NVMe SSDs.
