4TB M.2 NVMe drive for desktops and laptops

The Kingston NV3 is a 4TB internal solid-state drive built for desktop PCs, gaming laptops, notebooks, mini PCs and all-in-one systems. It uses the M.2 2280 form factor with a single-sided 2.3mm PCB that fits slim chassis and portable devices. The drive targets users who need large capacity for games, media files, video editing projects and daily workloads.

PCIe 4.0 x4 interface

The decisive specification is the PCIe 4.0 x4 NVMe interface, which delivers maximum sequential read speeds up to 6000MB/s and write speeds up to 5000MB/s. Sustained performance matches those peaks, while random access reaches 480000 IOPS read and 450000 IOPS write. Endurance is rated at 1280TBW with an MTBF of 2000000 hours, backed by the Phison PS5021-E21 controller and 3D TLC NAND.

Single-sided design needs only an M.2 NVMe slot

Installation requires a standard M.2 NVMe edge-connector slot; the single-sided layout clears tight spaces in thin notebooks and compact builds. Low power draw of 0.07W idle and 3.2W active reduces thermal load, so passive cooling is sufficient without an extra heatsink. The drive withstands 1000G shock and 20G vibration, making it suitable for portable game devices and mobile workstations.

Questions about this item

Will the single-sided M.2 2280 board fit a slim laptop with a 2.3mm slot height limit?

Yes, the drive uses a single-sided PCB measuring 2.3mm thick, so it fits slim notebooks and compact chassis that accept standard M.2 2280 modules.

Does the 4TB model need an extra heatsink for sustained 6000MB/s reads?

The NV3 is designed for passive heat dissipation; typical active power is 3.2W and idle power 0.07W, so no additional heatsink is required for normal desktop or laptop workloads.

What endurance rating does the 4TB drive carry for heavy write workloads?

The drive is rated for 1280TBW total bytes written and an MTBF of 2000000 hours, covering heavy gaming, video editing and daily office use.
