Why would a Gen4 SSD run at only half its advertised speed?

This occurs when the NVME M.2 Gen4 SSD is installed in an older PCIe 3.0 M.2 slot. The slot's bandwidth limits the speed to Gen3 levels, which is about half of Gen4. To achieve full advertised speeds, a PCIe 4.0 (or newer ) M.2 interface is required.

How can I check if my computer supports PCIe Gen4?

Desktops: Press Win+R → msinfo32→ find the motherboard model and search specifications online to confirm further. Laptops: Please consult the laptop manufacturer's official specifications or support team for this information. or ask SIX Tech Team.

Should I buy this if my PC only has PCIe 3.0?

Yes, it's still an excellent choice. You'll get the fastest speeds possible on your current system, and it's a smart investment that will unlock its full potential when you upgrade to a Gen4 PC in the future.

Is it compatible with a latest PCIe 5.0 slot?

Yes. The SIX X7400 is fully backward compatible with PCIe 5.0 slots. It will perform at its maximum Gen4 speed, providing an excellent experience on the latest platforms.
