Our take on the Lexar NQ780 4TB PCIe Gen 4x4 NVMe M.2 Internal SSD

The Lexar NQ780 is a 4TB M.2 2280 internal SSD using TLC NAND over a PCIe Gen 4x4 NVMe interface. Lexar rates it at up to 7,000 MB/s sequential read and 6,000 MB/s sequential write, which puts it in the same class as other mid-tier Gen 4 drives. The 4TB capacity is the draw: it holds a large game library or media project on one drive without a second slot. It suits desktop and laptop builders who want big capacity and Gen 4 speed without paying flagship prices. It is not a top-tier drive for sustained heavy writes, so buyers with constant large transfers should weigh it against drives with DRAM caches and higher endurance ratings.

Pros
  • 4TB capacity in a single M.2 2280 drive
  • Up to 7,000 MB/s read and 6,000 MB/s write
  • TLC NAND rather than QLC
  • PCIe Gen 4x4 NVMe interface
  • Fits desktops, many laptops and PS5
Cons
  • No DRAM cache listed, which can slow sustained writes
  • Endurance rating not published in the specs
  • Runs warm under long transfers, so a heatsink helps
  • Not a flagship drive for heavy write workloads

Questions and answers

Is the Lexar NQ780 fast enough for gaming?
Yes. Its Gen 4 speeds of up to 7,000 MB/s read and 6,000 MB/s write are well beyond what games need for fast load times.
Does it fit a PS5?
It is an M.2 2280 PCIe Gen 4x4 NVMe drive, which is the form the PS5 takes. Add a heatsink, since the PS5 expects one.
Does it have a DRAM cache?
The specs do not list a DRAM cache. Expect write speed to drop during very large sustained transfers compared with DRAM-equipped drives.
What kind of memory does it use?
It uses TLC NAND, which generally holds up better under heavy writes than QLC drives.
What is in the box?
The drive comes in its original retail packaging with a minimum one-year warranty. Mounting screws are not listed, so check your motherboard or laptop for them.
Is it worth it over a smaller Gen 4 drive?
If you need one drive to hold a large library, the 4TB capacity is the reason to pick it. For light use, a smaller drive does the same job.
