Your desktop might already support one of the best storage upgrades nobody thinks to try

U.2 is an enterprise storage standard that's rarely considered for desktop PC upgrades, but it can offer a compelling value proposition — especially when buying used enterprise drives. U.2 drives feature higher endurance, power-loss protection, and robust thermal design compared to consumer M.2 drives. The main drawbacks are limited native support on consumer motherboards (requiring a PCIe or M.2 adapter), the extra research needed when buying used hardware, and limited availability. Workstation boards often include native U.2 support. Popular used options include the Intel P4500/P4600, Samsung PM983, and Micron 9200 series.
