HP 5MS22AA#ABC EX950 512GB NVMe M.2 Internal SSD

The HP EX950 512GB is an M.2 NVMe solid-state drive that leverages a PCIe 3.1 x4 interface to deliver read and write speeds far beyond what traditional SATA SSDs can achieve. Built with 3D TLC NAND flash, the EX950 stacks memory cells vertically to increase density and efficiency, resulting in a drive that balances strong everyday performance with competitive pricing. The M.2 2280 form factor plugs directly into your motherboard's M.2 slot, eliminating the need for data and power cables and freeing up space inside your case.

At 512GB, the EX950 provides enough capacity for a Windows or Linux installation, a full suite of productivity and creative applications, and a reasonable library of documents and media. It is especially well-suited as a boot drive or primary application drive where fast random read and write performance translates directly into a snappier user experience. While the PCIe Gen 3 interface means it won't match the peak sequential speeds of newer Gen 4 NVMe drives, real-world differences in everyday tasks are often marginal. For users building or upgrading a system with a Gen 3-capable M.2 slot, the HP EX950 delivers reliable NVMe performance without overspending.
