Viper P400 Lite 4TB NVMe drive

The Patriot Viper P400 Lite is a 4TB M.2 2280 internal SSD built for consumer workloads. It connects through a PCIe 4.0 x4 interface and follows the NVMe 2.0 protocol. The drive uses a DRAM-less design with Host Memory Buffer support for everyday responsiveness.

Sustained performance without a heatsink

Sequential speeds reach up to 3500 MBps read and 2700 MBps write under typical burst conditions. The controller operates within a 0 °C to 70 °C range and relies on a graphene heatshield rather than a metal heatsink to manage thermals. A 4000 TBW endurance rating backs long-term write durability for video editing and heavy multitasking.

Compatibility checks before ordering

Verify that your motherboard or laptop provides an M.2 2280 slot wired for PCIe 4.0 x4 and NVMe signalling. The single-sided 2280 form factor fits most modern boards, but some compact systems only accept shorter modules. Confirm the platform can supply sufficient airflow for the heatshield to stay within the rated temperature window.

Questions about this item

Will this 4 TB M.2 2280 drive fit inside a PlayStation 5 console?

Yes, the drive is listed as compatible with PS5 and uses the M.2 2280 form factor with a PCIe 4.0 x4 interface that meets Sony's requirements.

My motherboard only has a PCIe 3.0 M.2 slot — will the drive still work?

The drive will operate in a PCIe 3.0 slot, but sequential read and write speeds will be limited to the 3.0 bandwidth ceiling rather than the rated 3500 MBps read and 2700 MBps write.

Does the drive include a heatsink, or do I need to add one for sustained workloads?

The drive ships without a heatsink; the graphene heatshield is integrated, but a motherboard M.2 heatsink or third-party cooler is recommended for heavy sustained writes.
