Will any NVMe SSD fit my motherboard or laptop?

Check the M.2 slot length, usually 2280, and the supported PCIe generation. Some laptops and consoles have specific size and heatsink requirements, so confirm clearance before buying.

Is a PCIe 4.0 or 5.0 drive worth it over PCIe 3.0?

Newer generations offer higher peak speeds, but real-world gains depend on the task and whether your system supports them. For general use, the difference is often smaller than the headline figures suggest.

Do NVMe SSDs need a heatsink?

Faster drives can run warm and may benefit from a heatsink to maintain sustained performance. Many motherboards include one, and some drives ship with their own, so check before adding another.
