SATA and PCIe m. what is the difference between 2 drive?

The main difference is that a PCIe and SATA m. 2 drives with different controllers. PCIe is faster in both. SATA usually compatible with a broader system, and better support in the old model. If the system has a m. 2 PCIe slots, m. with the same key 2 SATA SSD will be suitable for the slot but unable to work, and vice versa. Some systems are dual mode, can accept SATA and PCIe drive at the same time.

What is the difference between 2260 ds and 2280 ss?

These Numbers determine the m. 2 physical size of the drive. 2260 22 mm wide, 60 mm long, and 2280 long and 80 mm. Some systems will also support a variety of lengths of m. 2. We are currently in m. 2 SSD with 2280 variants. 'ds' and' ss 'double or single, refers to the NAND how to placed on the circuit board.

How important is the gap?

For Crucial the farce of PCIe SSD, we drive only the M key, this means that they are unable to load the B key slot (usually by the SATA m. 2 devices use). Our SATA m. 2 equipment has B and M keys, for maximum compatibility.
