The Patriot P400 Lite is a 1TB M.2 2280 PCIe 4.0 x4 NVMe SSD with sequential speeds of up to 3,500MB/s read and 2,700MB/s write, suited to consumer PCs needing responsive everyday storage and faster file transfers.
Recommended For
- PC builders adding an affordable 1TB NVMe drive for Windows, applications, and everyday files; a 1TB P400 Lite was tested at near its advertised sequential speeds in standard benchmarks.
- Gamers who want a 1TB M.2 drive for storing and launching a game library, especially when adding capacity to a PC; its tested copy performance covered both large files and mixed game-folder files.
- Laptop owners seeking a slim M.2 2280 storage upgrade, provided their laptop supports PCIe NVMe drives; Patriot positions the P400 Lite for PC and laptop use and specifies a thin graphene heatshield.
- Remote workers and students who need extra space for documents, applications, and personal files, but do not routinely write very large datasets; one review used the drive as added capacity for remote-work files and games.
Real-World Use Scenarios
- For a Windows PC’s operating system, apps, and everyday files, use the P400 Lite as the main drive; its NVMe storage is intended for quick data access, though actual responsiveness depends on the rest of the system.
- Keep frequently played games on the drive to manage a PC game library; a test copying a mixed-size game folder showed fast transfers, but it does not establish specific game loading times.
- Move folders containing a mix of large files and smaller program files between drives; in one test, the P400 Lite completed copies of ISO, program, and game folders, with results varying by file mix and system setup.
- Use it for occasional large media or project-file writes; one 300GB write test found that performance slowed after roughly 94GB, so it is less suited to uninterrupted, very large transfers than to routine file storage and transfers.

Reference Q&A
Q: Patriot P400 Lite or WD Blue SN580 1TB—which should I buy?
A: Choose the P400 Lite if it costs less and you mainly need storage for everyday computing or gaming. Choose the SN580 if you often copy large files: it has higher rated sequential speeds (up to 4,150MB/s read and write versus 3,500/2,700MB/s for the P400 Lite), and a direct multi-drive review found the SN580 generally faster in its copy tests. Both carry five-year warranties.
Q: Is the Patriot P400 Lite enough, or should I get a WD Black SN770?
A: For everyday PC use and gaming, the P400 Lite’s rated speeds of up to 3,500MB/s read and 2,700MB/s write may be sufficient. Choose the SN770 if you want higher rated sequential performance—up to 5,150MB/s read and 4,900MB/s write for the 1TB model—or regularly handle large transfers. The SN770’s additional rated speed is most relevant to compatible workloads, not a guarantee of noticeably faster everyday use.
Q: Patriot P400 Lite or the original Patriot P400—which is faster?
A: The original 1TB Patriot P400 has higher rated sequential speeds—up to 5,000MB/s read and 4,800MB/s write, compared with up to 3,500/2,700MB/s for the P400 Lite. It may suit workloads that benefit from faster sequential transfers; the P400 Lite is the practical pick if its lower speed ceiling meets your needs and you value its five-year warranty. Tom’s Hardware lists a three-year warranty for the original P400, versus Patriot’s five-year warranty for the P400 Lite.
Q: Will this SSD fit and work in my laptop or desktop?
A: It fits systems with an available M.2 2280 slot that supports PCIe NVMe SSDs. Check your device’s specifications first: an M.2 slot that supports only SATA, or a different drive length, may not be compatible. A PCIe Gen 3 slot may run the drive at Gen 3 speeds rather than its rated Gen 4 speeds.
Q: Does it come with a heatsink?
A: It does not include a separate heatsink. The product information lists a slim graphene heatshield and thermal-throttling technology, but these are not the same as a full heatsink. Check whether your device provides SSD cooling or requires a separately fitted heatsink.
Q: Is this a good choice for everyday computing and gaming?
A: It can suit everyday computing, app storage, and game storage in a compatible system. The 1TB capacity and stated sequential speeds of up to 3,500MB/s read and 2,700MB/s write are relevant to those uses. Actual performance depends on the system and workload; the drive has no DRAM cache and uses HMB.
Q: Can I use this SSD in a PS5?
A: The product data lists PCIe Gen 4 x4 and M.2 2280, but its maximum stated read speed is 3,500MB/s and it has no separate heatsink. Those details do not establish that it meets PS5 expansion requirements; verify the console’s current SSD speed and cooling requirements before buying.
Q: Is the Patriot P400 Lite a sensible budget 1TB SSD choice?
A: It may suit a budget PC build or storage upgrade if its price is competitive. It is a 1TB PCIe 4.0 x4 NVMe M.2 2280 drive rated for up to 3,500MB/s reads and 2,700MB/s writes. Check comparable drives and your workload before choosing; the listed specs do not establish that it is the best value at every price.
Q: Will the P400 Lite work in a PCIe Gen 3 M.2 slot?
A: A Reddit discussion specifically asks about using this Gen 4 drive with a Gen 3 motherboard. It can be a candidate if the slot supports M.2 NVMe drives, but it will run at the slot’s supported PCIe generation, so Gen 4 maximum speeds should not be expected from a Gen 3 slot. Confirm the motherboard’s M.2 specifications.
Q: Is the P400 Lite suitable as a Windows drive and for everyday gaming?
A: Its 1TB capacity and NVMe interface make it a possible choice for a consumer PC used for Windows, apps, and games. The listed specifications say it has no DRAM cache and uses HMB, so its sequential-speed rating alone does not establish performance in every workload. For frequent, sustained heavy writes, compare drives with workload-specific reviews and endurance information.
