How they differ
The decision usually comes down to interface (PCIe Gen5 vs Gen4), sustained write speed, DRAM cache, and rated endurance. Judge each option on real-world load times, sustained transfer speed, and whether it throttles without a heatsink, and make sure whichever you pick suits a motherboard M.2 slot with the lanes to feed it.
