NGFF M.2 PCIe M-Key Extension Card with 20 CM Cable

‌An NGFF (Next Generation Form Factor) M.2 PCIe M-Key Extension Card with a 20 cm cable is typically used to extend the reach of an M.2 NVMe SSD to a different location in a computer case or to an external enclosure. Here's a breakdown of its components:

NGFF M.2: The "NGFF" refers to the Next Generation Form Factor, which is now more commonly referred to as M.2. This is a small form factor for internal solid-state drives (SSDs) in devices such as laptops, desktops, and tablets.

PCIe M-Key: The "M-Key" is a specific connector type for M.2 slots that supports PCIe (Peripheral Component Interconnect Express) connections. An M-Key is used primarily for high-speed NVMe (Non-Volatile Memory Express) SSDs, which communicate via the PCIe bus for faster data transfer compared to older SATA SSDs.

Extension Card: The extension card allows an M.2 drive to be connected via the M-Key slot, and the extension card typically has a longer form factor that can plug into a different slot in your system or be placed elsewhere inside the case.

20 cm Cable: The cable is 20 centimeters long and allows the M.2 SSD to be mounted further away from the motherboard's M.2 slot. This can help in situations where the drive needs to be installed in a more convenient or cooler location within a custom PC setup.

These extension cards are useful in system builds where direct installation of the M.2 drive on the motherboard isn't possible or optimal due to space constraints or thermal concerns.
