KingSpec NX-256 2280 PCIe 3.0 x4 NVMe SSD

The KingSpec NX-256 2280 is a 256GB internal solid-state drive built for consumer desktops and laptops. It uses the M.2 2280 form factor with a PCI-Express 3.0 x4 interface and NVMe 1.3 protocol. The drive employs 3D NAND flash for storage density and endurance.

No bundled accessories

The product ships as a bare drive without a heatsink, extra cables, cloning utilities or mounting hardware. Installation relies on the host system's M.2 slot and native NVMe driver support. Performance figures reflect the drive alone.

256GB capacity with 120TB written endurance

The drive offers 256GB of usable capacity and a terabytes-written rating of 120TB. Sequential speeds reach up to 3200 MBps read and 1600 MBps write. Random performance hits 380000 IOPS read and 320000 IOPS write.

Questions about this item

How many terabytes can be written to the NX-256 2280 before the drive reaches its rated endurance limit?

The drive is rated for 120 TBW, so you can write up to 120 terabytes over its lifetime before the endurance limit is reached.

Which performance limit appears first during long sequential writes on this PCIe 3.0 x4 SSD?

Sequential write speed caps at 1600 MBps, so sustained large-file transfers will hit that throughput ceiling before other limits.

What is the active power draw of the NX-256 2280 when it runs continuously under load?

Active power consumption is 4.66 W, so the drive draws that amount from the system during sustained operation.
