Capacity and interface

The KingSpec NX-128 2280 is a 128GB internal SSD built on the M.2 2280 form factor with a PCIe 3.0 x4 interface and NVMe 1.3 protocol. It targets desktop and laptop users who need a compact boot or secondary drive for everyday workloads.

Sustained workload behaviour

The drive uses 3D NAND flash and supports HMB technology to maintain performance without a dedicated DRAM cache. Rated endurance is 60TB written and the MTBF is 1000000 hours, indicating consistent operation across long write sessions within the 0°C to 70°C operating range.

Deciding specification

The PCIe 3.0 x4 NVMe 1.3 interface delivers sequential reads up to 2200 MBps and writes up to 800 MBps, with random performance of 380000 read IOPS and 320000 write IOPS. This single interface and speed profile determines whether the drive matches the host system and workload requirements.

Highlights

Questions about this item

Does the drive run hotter without a heatsink when it handles sustained NVMe workloads all day?

The KingSpec NX-128 2280 ships without a heatsink and is rated for 0 °C to 70 °C operating temperature, so sustained NVMe 1.3 loads will rely on your motherboard airflow to stay within that range.

What motherboard slot and protocol does this 128 GB M.2 2280 drive need to function?

It requires an M.2 2280 slot wired for PCI-Express 3.0 x4 with NVMe 1.3 support; a SATA-only M.2 slot will not work.

Will the PCIe 3.0 x4 interface slow down older SATA SSDs I keep in the same system?

The NX-128 2280 uses its own PCIe 3.0 x4 lanes and NVMe 1.3 controller, so it does not share bandwidth with or affect any SATA drives already installed.
