Manufacturer Contact Info

The Patriot P400 Lite is a 2TB M.2 2280 PCIe 4.0 x4 NVMe SSD for desktop or laptop users seeking fast internal storage, with sequential speeds up to 3,500MB/s read and 2,700MB/s write. Its slim graphene heatshield and thermal throttling support suit everyday computing, gaming, and creative workloads.

Recommended For

PC gamers adding room for a sizable game library who want a 2TB internal drive for installs and everyday loading rather than a top-tier sequential-speed upgrade.
Desktop or laptop owners replacing or adding an M.2 2280 drive for Windows, applications, and routine file storage, provided their system supports PCIe NVMe.
ROG Xbox Ally owners seeking internal storage expansion: Patriot lists the P400 Lite as compatible with the handheld.
Budget-conscious PC builders who prioritize 2TB capacity and everyday responsiveness over premium-drive speeds; an independent 2TB test includes file-copy and benchmark results for this model.

Real-World Use Scenarios

When upgrading a PC from a hard drive, users can install Windows and everyday apps on the P400 Lite; the SSD-based system should feel more responsive during startup and app launches, though results depend on the rest of the PC.
For a PC game library, users can keep multiple games installed on the 2TB drive and load game files from SSD storage; actual load times vary by game and system.
When moving folders between drives or backing up large files, users can use the P400 Lite as an internal working or destination drive; its tested copy results cover large files as well as mixed game and program folders.
In a compatible laptop or desktop with an available M.2 2280 slot, users can add the P400 Lite for extra storage or replace an existing drive; check the device’s supported drive length and PCIe/NVMe compatibility before installation.
