Kingston SNV3S 4TB NVMe SSD

The Kingston SNV3S/4000G is a 4TB internal solid state drive built on the M.2 2280 form factor. It connects through a PCIe 4.0 x4 NVMe interface and delivers sequential reads up to 6000 MBps and writes up to 5000 MBps. The drive uses a DRAM-less design with host memory buffer support and carries a 2000000 hour MTBF rating.

Suits high-capacity NVMe upgrades

This drive suits users who need a single 4TB NVMe volume for large game libraries, media projects or heavy multitasking on a PCIe 4.0 platform. The 2.30mm height fits standard M.2 slots in laptops and desktops. Buyers whose systems only support PCIe 3.0 or earlier will not reach the stated 6000 MBps read ceiling and should verify motherboard compatibility first.

PCIe 4.0 x4 NVMe interface decides fit

The single specification that determines whether this is the right part is the PCIe 4.0 x4 NVMe interface. The motherboard must provide an M.2 slot wired for PCIe 4.0 x4 to achieve the quoted 6000 MBps read and 5000 MBps write speeds. If the slot is limited to PCIe 3.0 x4 or x2, throughput will be lower and a different drive may offer better value.

Questions about this item

How much heat does the 4TB NVMe drive add when it runs continuously at up to 6000 MBps read?

The drive is rated for 0 °C to 70 °C operating temperature and its Gen 4x4 controller is designed for lower power consumption and reduced heat during sustained workloads.

What motherboard slot and protocol are required for the M.2 2280 PCIe 4.0 x4 NVMe SSD to function?

An M.2 2280 key‑M slot wired for PCIe 4.0 x4 with NVMe support is needed; the drive has no DRAM cache and relies on host memory buffer.

Will the 4TB NVMe drive work in a system that only has PCIe 3.0 M.2 slots?

Yes, the PCIe 4.0 x4 NVMe drive is backward compatible and will operate at PCIe 3.0 speeds when installed in a PCIe 3.0 M.2 slot.
