Non-contractual photos

The visuals on this page are supplied by the manufacturer. They are frequently produced for a whole range — not for the exact model you are viewing: what you see in the photo is never a promise of what is included.

No exchange, return or cancellation will be accepted on the grounds that something seen in a photo (accessory, port, colour, keyboard layout, packaging…) is not found on the delivered product. Only the specifications written on the page are binding for the order.

What the image does not guarantee:

  • Capacity : the capacity printed on the product photographed illustrates the range; the one sold is that of the title and the specifications.
  • Format and interface : 2.5 or 3.5 inch, SATA, NVMe M.2, with or without a heatsink: the photo is not enough to tell.
  • Drives not supplied : external enclosures, docking stations and NAS servers ship without a drive, unless explicitly stated.
  • Accessories : cables, adapters, caddies and screws are supplied only if the specifications say so.
  • Colour : one image often serves several colours, and the shade you see depends on studio lighting as much as on your screen settings; the colour sold is the one in the title and the specifications.
  • Props and accessories : the items shown around the product (cables, stands, decorative objects, content displayed on screen) are not included unless explicitly stated.
  • Packaging : boxes, labels and bundles change with the manufacturer's revisions: the packaging delivered may differ from the one in the photo.

What is binding: the product title, this page's technical specifications, the description and, when provided, the manufacturer's PDF datasheet available in the downloads.

Frequently asked questions about this product

What does “M.2 2280” mean, and how do I know if my PC accepts it?
They are the module's dimensions: 22 mm wide by 80 mm long, the most widespread form factor on desktop motherboards and recent laptops. Locate the machine's M.2 slot and its screw mounting point: if it sits 80 mm from the connector, the module is the right length.
How thick is this module, and does it fit in a thin laptop?
Only 2.45 mm, for 6 g. That is flat enough to slip under the cover of an ultrabook, where a module topped with a heatsink would not fit. This thickness stays the same from the 512 GB capacity up to the 4 TB model in the series, with only the 8 TB version being slightly heavier, at 7.6 g.
What speeds does the NM790 claim in its 512 GB version?
7,200 MB/s read and 4,400 MB/s write sequential, in a PCIe Gen4 x4 slot. These are the figures specific to the 512 GB capacity, as the other capacities in the series have their own profile. At this rate, copying a folder of several gigabytes takes a matter of seconds.
How many terabytes written can this 512 GB drive handle?
500 TB, or nearly a thousand complete fills of the drive. That is half the endurance of the 1 TB version, rated at 1,000 TB: on a workstation that writes a lot — video editing, daily backups, a virtual machine — the higher capacity also doubles the endurance.
Can this SSD handle being carried around every day?
Yes. There are no moving parts inside. It withstands shocks of 1,500 G over 0.5 ms (half-sine wave) and vibration from 10 to 2,000 Hz up to 20 G, thirty minutes per axis. The stated mean time between failures is 1,500,000 hours, and it operates in complete silence.
What temperature range does the NM790 operate in?
From 0 to 70 °C in operation. When powered off, the range extends from -40 to 85 °C, which covers transport or prolonged storage with no risk to data already written. As the module has no fan and no moving parts, nothing wears out apart from the memory itself.
What difference does NVMe make compared with a SATA SSD?
It uses PCIe lanes rather than the SATA bus, which gives it a stated bandwidth up to ten times higher. In practice, you notice it when the system boots, when games load and when large files are copied, more than in everyday office work.
Is the drive new and under warranty?
It is new and comes with Lexar's official manufacturer warranty, with your invoice serving as proof. The NM790 has no moving parts: the only thing consumed through use is its write endurance, set at 500 TB for this 512 GB capacity.
