The Samsung 990 EVO Plus 4TB is a high-capacity M.2 NVMe storage solution engineered for power users, content creators, and data-heavy professional workstations. It addresses the increasing demand for massive local storage without sacrificing throughput, providing a significant density upgrade for modern systems using the PCIe 4.0 x4 or PCIe 5.0 x2 interface.
This drive achieves sequential read speeds up to 7,250 MB/s, utilizing Samsung's advanced V-NAND technology to provide a 50% speed increase over its predecessor. With a 4TB capacity, it eliminates the need for secondary storage drives in high-end laptops and small form factor (SFF) builds, allowing for massive libraries of 4K/8K video assets, complex 3D models, or expansive software development environments.
Deployment is intended for high-performance client computing. Its power-efficient design offers up to 73% better performance-per-watt compared to previous models, making it ideal for thermal-constrained environments. The drive includes a heat spreader label for passive cooling. It is not designed for data center environments with constant, high-intensity write cycles (DWPD).
