Lexar NM790 1TB PCIe Gen4x4 NVMe M.2 2280 SSD LNM790X001T-RNNNG
Overview :
Lexar NM790 1TB PCIe Gen4 x4 NVMe M.2 2280 1TB Internal SSD is a PCIe-based solid-state drive built using NVMe protocol to deliver high sequential throughput and low-latency storage access for modern computing systems.
Lexar NM790 1TB operates through a PCIe 4.0 x4 interface, enabling faster data transfer rates compared to SATA-based storage. The NVMe protocol reduces communication overhead and improves parallel processing efficiency on compatible systems.
The drive uses an M.2 2280 form factor, allowing installation into supported desktop motherboards, laptops, and PlayStation 5 storage expansion slots that accept PCIe NVMe drives.
Storage architecture includes Host Memory Buffer (HMB) 3.0 technology and dynamic SLC caching, allowing the Lexar NM790 1TB to utilize system memory instead of onboard DRAM for cache operations while maintaining performance consistency during sustained workloads.
A 12nm controller is integrated to balance performance efficiency and thermal characteristics. Power consumption is optimized compared to DRAM-cache-enabled PCIe Gen4 SSDs, which can benefit mobile environments requiring extended battery operation.
Compatibility depends on motherboard or device support for PCIe NVMe M.2 slots. Lexar NM790 1TB will operate at reduced speeds when installed in PCIe Gen3 systems and is not compatible with SATA-only M.2 slots.
Best suited for
• Desktop or laptop NVMe storage upgrades
• PCIe Gen4 gaming or productivity systems
• High-speed application and OS drives
• Compact builds using M.2 storage
Not suitable for
• SATA M.2 slots
• 2.5-inch SATA bays
• Systems without NVMe support
• PCIe Gen4 unsupported legacy platforms expecting full rated speeds
