Do Macbooks Have M 2 Slots?

M.2, formerly known as the Next Generation Form Factor (NGFF), is a specification for internally mounted computer expansion cards and associated connectors. It replaces the mSATA standard, which uses the PCI Express Mini Card physical card layout and connectors.

M.2 is very flexible and is widely used as an interface for SSDs in laptops and other devices.

The M.2 standard was developed by Intel in collaboration with PC peripheral manufacturers including HP, Lenovo, SanDisk, and Samsung.

The goal was to develop a standard internal form factor for laptop computers that would be smaller than existing mSATA SSDs while offering similar or better performance.

M.2 cards are available in two widths: 22 mm (80-pin) and 30 mm (110-pin). The 22 mm card is 42% the size of a traditional 2.5-inch SSD, while the 30 mm card is 67% the size of a 2.

5-inch SSD. M.2 cards are also available in two lengths: 42 mm (2242) and 80 mm (2280). The shorter length is designed for use in Ultrabooks, while the longer length is designed for use in desktop computers and servers.2 cards can use either the SATA or PCIe bus for data transfer. SATA-based M.

2 cards are typically used for storage applications, while PCIe-based M.2 cards are typically used for networking applications such as Wi-Fi or Ethernet adapters.2 cards are available in four different form factors:

Single-sided: The components are located on one side of the PCB only; this allows for a thinner card profile but limits component density and cooling options.

Double-sided: The components are located on both sides of the PCB; this allows for increased component density but can make cooling more difficult due to the increased thermal mass.

Double-sided with heatsink: The components are located on both sides of the PCB and a heatsink is attached to aid in cooling; this option offers the best cooling potential but also the highest card profile due to the addition of the heatsink.

Double-sided with active cooler: The components are located on both sides of the PCB and an active cooler is used to aid in cooling; this option offers good cooling potential but requires additional power from an external power source such as a USB port or AC adapter.
