There are different types of M2 slots, but all of them allow for the same basic functionality: data transfer between devices. The three most common types of M2 slots are found on mobile devices, laptops, and motherboards.
Mobile M2 slots are the most common type and are found on phones and tablets. They use a standard Micro-USB connector and can generally handle data transfers between two devices at once.
Laptops typically have more mobile M2 slots than motherboards do, since they’re designed to be portable. Motherboards, on the other hand, typically have more M2 slots for storage purposes.
Laptop M2 slots are similar to mobile M2 slots in that they use a Micro-USB connector and can generally handle data transfers between two devices at once. However, laptop M2 slots are usually found on the back of the laptop instead of the front and are meant for storage rather than data transfer.
Motherboard M2 slots are the least common type of M2 slot and are found on only a few select motherboards. Motherboard M2 slots are unusual in that they use a PCIe connector instead of a Micro-USB connector.
PCIe connectors are more expensive than Micro-USB connectors, so motherboard M2 slots are typically reserved for high-end systems or cases that require extra ports.
