WD Blue SN5000 4TB NVMe SSD vs Samsung 870 EVO 1TB SATA SSD

These are different classes of drive, not close rivals. The WD Blue SN5000 is a PCIe Gen4 NVMe drive with roughly ten times the sequential throughput of the SATA 870 EVO, and it comes in 4TB against the Samsung's 1TB. The 870 EVO is the safer, more universal pick: a 2.5-inch SATA drive that drops into almost any desktop or laptop, with a long track record and a 4.8 rating from about 29,000 owners. Buy the WD for a modern machine with an M.2 slot and a need for speed and space. Buy the Samsung for an older PC, a laptop with only a SATA bay, or a secondary drive where plug-and-play matters more than throughput.

• Choose the WD Blue SN5000 if your board or laptop has an M.2 2280 PCIe Gen4 slot and you want a fast, high-capacity drive for games, large video projects or a big working library.
• Choose the Samsung 870 EVO if you need a 2.5-inch SATA drive for an older desktop or laptop, or a dependable secondary drive that installs without any PCIe or NVMe setup.
