M2 slots are essentially smaller versions of M3 slots that are found on motherboard chipsets. They are designed specifically for PCI Express expansion cards, and are divided into two categories – Type-M and Type-A.
Type-M slots are the most common type, and they support both PCIe and SATA devices. Type-A slots only support PCIe devices, and they are typically used for graphics cards or RAID controllers.
M2 slots can offer significant performance benefits over M3 slots, especially when it comes to graphics cards. They also allow for additional storage space on a motherboard, which is useful if you want to install a larger hard drive or SSD.
Overall, M2 slots are a great option if you want to install a high-performance graphics card or storage device. They provide significant performance benefits over M3 slots, and they also allow for additional storage space on your motherboard.
