Patriot P400 Lite 4TB Gen4 NVMe SSD
4TBPCIe Gen4 x4 NVMe3500 MB/s ReadGraphene Heatshield
The Patriot P400 Lite 4TB is an affordable high-capacity PCIe Gen4 x4 NVMe M.2 2280 internal SSD that delivers up to 3,500 MB/s read and 2,700 MB/s write, with enough room to hold a huge game and media library. Identified by part number P400LP4KGM28H, it uses an efficient design with a slim graphene heatshield to keep temperatures down, plus SmartECC and thermal throttling for stable, reliable operation. Rated for a generous 1,800 TBW with a 5-year warranty and low power draw, it is a sensible way to add lots of fast storage. Typically in stock with fast delivery across Cyprus.
Compatibility note
This is an internal M.2 2280 PCIe Gen4 NVMe drive with a slim graphene heatshield (not a bulky heatsink), so it fits laptops and desktops. It is an NVMe drive, not SATA, and is backward compatible with PCIe 3.0 at lower speeds. As an efficient entry Gen4 drive, its speeds are below high-end Gen4 SSDs, which keeps the price low. Confirm your device has an 80mm M.2 NVMe slot.
Best For
✓ Affordable 4TB bulk NVMe storage
✓ Huge game and media libraries

Frequently Asked Questions
Will the Patriot P400 Lite work in my laptop or motherboard?
Yes, if it has a free M.2 2280 NVMe (PCIe) slot. It is a PCIe Gen4 x4 drive that also runs in PCIe 3.0 slots at Gen3 speeds. It is not a SATA M.2 drive, so the slot must support NVMe.
Is 4TB on a single M.2 drive worth it?
Yes, if you need lots of fast storage. The P400 Lite 4TB holds a huge game and media library on one drive at an affordable price, with a generous 1,800 TBW endurance rating for years of use.
Why is the P400 Lite cheaper than other Gen4 drives?
It is an efficiency-focused entry Gen4 drive: it trades the very top speeds (7,000 MB/s) for a lower price, lower power draw and a slim graphene heatshield, while still being much faster than SATA.
What should I know before buying the 4TB P400 Lite?
Confirm you have an M.2 2280 NVMe PCIe slot. It reaches up to 3,500/2,700 MB/s, is rated at 1,800 TBW, has a slim heatshield for laptops, and is backed by a 5-year warranty. It is a value high-capacity Gen4 drive rather than a peak-performance one.
Singular Expert Insight
The P400 Lite 4TB is about affordable capacity: a cool-running, efficient Gen4 drive that holds an enormous library at a friendly price per gigabyte, with strong 1,800 TBW endurance. At up to 3,500 MB/s it is far faster than SATA; if you want full Gen4 speed (5,000-7,000 MB/s) the Patriot P410 or Crucial P310 step up, and for the fastest 4TB the Lexar NQ790 is worth comparing.
