Capacity and interface

The KingSpec XG7000 is a 4 TB internal SSD built in the M.2 2280 form factor. It connects through a PCIe 4.0 x4 lane using the NVMe 1.4 protocol. The drive is intended for desktops, laptops and the PS5 console.

PCIe 4.0 x4 practical limits

Sequential throughput reaches 7400 MB/s read and 6600 MB/s write on a PCIe 4.0 platform. On a PCIe 3.0 slot the same drive will be limited to the 3.0 ceiling, so peak speeds cannot be realised. Random performance tops out at 720 000 read IOPS and 800 000 write IOPS.

Installation checks

Verify that your motherboard or laptop provides an M.2 2280 slot wired for PCIe 4.0 x4 and that the 2.1 mm module height clears any onboard heatsink or shield. The drive has no integrated heatsink, so confirm your platform supplies adequate airflow or add a third‑party spreader. Power draw peaks at 8.18 W active and 0.66 W idle.

Questions about this item

What capacity does the XG7000 come in?

The XG7000 is available as a single 4TB model with part number XG7000-4TB 2280.

What do the 7400 MBps read and 6600 MBps write figures mean in daily use?

They are peak sequential speeds; real-world throughput depends on the host controller, file sizes and thermal conditions.

Which interface and protocol does the drive use, and what limits its speed?

It uses PCI-Express 4.0 x4 with NVME 1.4; the four-lane Gen 4 link caps the maximum theoretical bandwidth.
