Lexar NM790 8TB PCIe 4.0 NVMe M.2 SSD

The Lexar NM790 is an M.2 2280 internal solid-state drive built on the PCIe 4.0 x4 interface. It targets users who need a single high-capacity NVMe drive for large media libraries, game installs or professional workloads.

Sequential read up to 7400 MB/s

The headline specification is the sequential transfer rate: up to 7400 MB/s read and 6500 MB/s write over PCIe 4.0 x4. Random read reaches 1,000,000 IOPS, so the drive keeps latency low when many small files are accessed simultaneously.

8 TB capacity with 1,500,000-hour MTBF

Eight terabytes provides headroom for hundreds of modern titles or multi-terabyte project files. The 1,500,000-hour mean time between failures rating indicates endurance for continuous operation, while HMB 3.0 and dynamic SLC caching sustain performance without a dedicated DRAM cache.

Questions about this item

How does the 7400 MB/s sequential read speed translate to real-world load times?

The 7400 MB/s read speed lets large game levels, video projects and OS files load in seconds rather than minutes, keeping workflows moving without long waits.

What does the PCIe 4.0 x4 interface limit in practice?

The PCIe 4.0 x4 link caps throughput at the drive's rated 7400 MB/s read and 6500 MB/s write, so performance scales with the slot's generation.

Will the M.2 2280 form factor fit my motherboard or laptop slot?

The 2280 length fits standard M.2 slots on desktops and most modern laptops; verify your device has a key-M NVMe socket before installing.
