The most common for SSDs are M-key (for NVMe) and B-key or B+M key (often for SATA, but can also support NVMe). An M-key NVMe SSD will only fit into an M-key slot. Understanding the differences and compatibility of M.2 keys and sockets is crucial to avoid attempting to install an incompatible drive. The physical size of the M.2 drive (e.How to Identify M.2 Slot is SATA SSD or NVME SSD/ PCIE (Full Guide)g., 2280, 2242) also needs to match the slot's physical support.
The question of does it matter which M.2 slot I use often surfaces when users are looking to put a second SSD or upgrade their primary drive2 NVMe SSD's..which slot to put OS on and does it matter?. For the most demanding users, prioritizing the slot use for performance is critical. If you have a high-end NVMe SSD, placing it in the top slot, the one closest to the CPU, is generally recommended for the best speeds. Some configurations might even warrant using M.2_1 for your OS drive and another high-performance drive in a secondary CPU-connected slot (if available) for games or frequently used applications.
