The Lexar EQ790 4TB pairs blistering PCIe Gen4 throughput with a generous 4 terabyte capacity in a slim M.2 2280 form factor. Built for creators, gamers, and professionals who refuse to compromise, the drive slides straight into any compatible motherboard or PlayStation 5 expansion bay and delivers an immediate, tangible upgrade.

HMB 3.0 and an intelligent SLC cache work together to keep latency low under sustained workloads, while 3D NAND flash provides the endurance to handle years of heavy reads and writes. Up to 7,000 MB/s sequential reads and 6,000 MB/s sequential writes turn slow load screens into a memory and shave minutes off large file transfers.

Adaptive power management throttles consumption to match demand, keeping thermals in check inside compact laptops and consoles without sacrificing peak performance when you need it. The result is a drive that stays cool and responsive whether you're rendering 8K footage, loading vast open-world games, or running AI inference locally.

The EQ790 is the right choice for anyone outgrowing a 1TB or 2TB drive and ready to consolidate their entire library, project archive, or game collection onto a single high-performance volume.
