Capacity and form factor

The KingSpec NXM-2TB is an M.2 2242 internal SSD with 2 TB of 3D NAND storage. It connects through a PCIe 3.0 x4 interface and follows the NVMe 1.3 specification. The drive fits ultrabooks, laptops, desktops and all-in-one systems that accept a 2242 M-key module.

Everyday headroom

Sequential reads reach 3500 MB/s and writes reach 3000 MB/s, while random 4 KB performance hits 330,000 read IOPS and 250,000 write IOPS. The 1000 TBW endurance rating supports heavy daily workloads, though sustained writes will eventually throttle once the SLC cache fills.

Thermals and power

Without a heatsink the controller relies on the motherboard thermal pad and airflow inside the chassis. Idle power sits at 0.61 W and active power at 3.6 W, keeping temperatures within the 0 °C to 75 °C operating range during typical workloads.

Questions about this item

Will the NXM-2TB fit in a laptop that only has an M.2 2280 slot?

No — the drive is built to the M.2 2242 form factor measuring 42.0 mm long, so it cannot occupy a 2280-length socket.

How can I verify the NXM-2TB is delivering its rated 3500 MB/s sequential read and 3000 MB/s sequential write after installation?

Run a synthetic benchmark such as CrystalDiskMark on an NVMe 1.3-compatible PCIe 3.0 x4 slot; results should approach the stated 3500 MB/s read and 3000 MB/s write figures.

Does the NXM-2TB package include a heatsink or mounting screw, or must I source them separately?

The drive ships without a heatsink and without a mounting screw; both items need to be supplied by the user or the host device.
