Lexar NM790 4 TB (LNM790X004T-RN9NG)

The Lexar NM790 is a line of internal M.2 2280 SSDs designed for gaming PCs, laptops, workstations, and PlayStation 5, delivering high-speed loading for games, applications, projects, and large files. The series uses the PCIe Gen4 x4 NVMe interface and is available in 512 GB, 1 TB, 2 TB, 4 TB, and 8 TB capacities. The Lexar NM790 employs Host Memory Buffer 3.0 and Dynamic SLC Caching, leveraging system memory and caching to maintain performance without a separate DRAM cache on the drive itself. Maximum speeds vary by capacity: 1–4 TB models reach up to 7400 MB/s read and 6500 MB/s write, the 512 GB variant achieves up to 7200 MB/s read and 4400 MB/s write, while the 8 TB model delivers up to 7000 MB/s read and 6200 MB/s write. For random operations, top-tier configurations deliver up to 1,000,000 IOPS read and 900,000 IOPS write, which is essential for multitasking, gaming, and creative applications. The Lexar NM790 operates within a temperature range of 0–70 °C, withstands shock loads of 1500G, and can serve as a primary system drive or high-speed project storage. When installing in a PS5 or compact PC, cooling requirements and heatsink clearance must be considered.
