M.2 SSD

M.2 solid-state drives (SSDs) have several features, including:

Size

M.2 SSDs are small and slim, resembling a chewing gum stick, and ideal for laptops, notebooks, and other portable devices. They are smaller than 2.5-inch SSDs and hard drives.

Performance

M.2 SSDs can read and write data faster than SATA or SAS SSDs, mainly if they use the NVMe protocol.

Power efficiency

M.2 SSDs are more power efficient than other SSDs, reducing heat generation and the risk of overheating.

Durability

M.2 SSDs are less likely to be damaged by vibrations and shock.

Flexible interface

M.2 SSDs support PCIe, SATA, USB 3.0, Bluetooth, and Wi-Fi.

Single- or double-sided

Single-sided M.2 boards are used in space-limited devices, while double-sided chips have greater storage capacity.

Physical size

M.2 drives come in different physical sizes, including 30 mm (2230), 42 mm (2242), 60 mm (2260), 80 mm (2280), and 110 mm (22110).

Logical interfaces

M.2 drives can connect to a system using a SATA controller or a PCI-E bus in x2 or x4 mode.
