FAQ

What interface does the Lexar NM620 use?

It uses a PCIe Gen3x4 interface with the NVMe 1.4 protocol on an M.2 2280 form factor.

Is the Lexar NM620 compatible with my laptop or desktop?

Yes - as long as your system has an M.2 2280 slot that supports PCIe x4 NVMe drives and your motherboard dials PCIe in the BIOS if required, the NM620 will install and operate normally.

Can I use the Lexar NM620 for gaming or creative work?

Absolutely - the drive offers strong sequential speeds and respectable IOPS for mainstream workloads, making it well-suited for game libraries, application load times and basic creative tasks like video/photo editing. However, for more extreme workloads you may consider Gen4 drives for even higher performance.

Does the Lexar NM620 require a heatsink?

While the drive is compact and low profile, if you are installing it in a system with limited airflow or an ultra-high-performance workload, fitting a slim M.2 heatsink or ensuring case airflow will help maintain optimal sustained performance.
