1TBPCIe Gen4 x4 NVMe3300 MB/s ReadGraphene Heatshield
The Patriot P400 Lite 1TB is an affordable PCIe Gen4 x4 NVMe M.2 2280 internal SSD that delivers up to 3,300 MB/s read and 2,700 MB/s write, an easy, budget-friendly way to add fast NVMe storage to a laptop or desktop. Identified by part number P400LP1KGM28H, it uses an efficient design with a slim graphene heatshield to keep temperatures down, plus SmartECC and thermal throttling for stable, reliable operation. With low power draw and a 5-year warranty, it is a sensible everyday upgrade that fits even slim laptops. 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.

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.
How much faster is the P400 Lite than a SATA SSD?
Considerably. At up to 3,300 MB/s read it is roughly 6x faster than a SATA SSD (around 550 MB/s) and far faster than a hard drive, making boot, app loading and file access noticeably quicker.
Why is the P400 Lite cheaper than other Gen4 drives?
The P400 Lite 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 1TB P400 Lite?
Confirm you have an M.2 2280 NVMe PCIe slot. It reaches up to 3,300/2,700 MB/s, draws little power, has a slim heatshield for laptops, and is backed by a 5-year warranty. It is a value Gen4 drive rather than a peak-performance one.
Singular Expert Insight
The P400 Lite is an efficient budget Gen4 drive: at up to 3,300 MB/s it is far faster than SATA and ideal for laptops thanks to its low power draw and slim graphene heatshield. If you want full Gen4 speed (5,000-7,000 MB/s), step up to the Patriot P410 or Crucial P310; if your system is only Gen3, the cheaper Patriot P320 is similar in real-world feel. For an affordable, cool-running upgrade, the P400 Lite is a solid pick. Compare options across our range of

Buyer’s Guide
Buy it if
You want an affordable, cool-running Gen4 NVMe upgrade for a laptop or desktop, much faster than SATA, with a slim graphene heatshield, low power draw and a 5-year warranty.
Skip it if
You want full Gen4 speed (5,000-7,000 MB/s), DRAM-cache performance, or a PS5-optimised drive — the P400 Lite is an efficiency-focused entry Gen4 drive.
Also consider
The Patriot P410 or Crucial P310 for faster Gen4, or the Patriot P320 if your system only has a Gen3 slot.
