M.2 2280 NVMe drive for consumer builds

The Helix-L MKNSSDHL250GB-D8 is a 250GB internal SSD built on 3D TLC flash with a Silicon Motion SM2263XT controller. It targets everyday computing workloads in laptops, ultrabooks and desktops that need responsive storage without enterprise cost.

PCIe Gen3 x4 slot required for full speed

The drive plugs directly into an M.2 2280 key-M socket wired for PCIe Gen3 x4, delivering up to 32 Gbps of bus bandwidth. No cables or drive bays are needed, freeing internal space and simplifying cable routing in compact chassis.

Steady throughput under sustained load

Sequential reads reach 2010 MBps and writes 1250 MBps while random performance holds at 200000 read IOPS and 260000 write IOPS. Active power draw stays at 4.5W with idle at 0.3W, and the controller supports L1.2 low-power state for thermal stability during long sessions.

Questions about this item

What sequential-write speed does the 250 GB Helix-L sustain before its SLC cache fills?

The drive writes at up to 1250 MBps while the SLC cache is active; after the cache fills the native 3D TLC speed will be lower.

How much heat and power does the SSD produce during all-day workloads?

Active power draw is 4.5 W and the operating range is 0 °C to 70 °C; the controller supports L1.2 low-power mode to reduce heat when idle.

Which motherboard slot and protocol are required for this M.2 2280 drive?

A motherboard with an M.2 2280 slot wired for PCIe Gen3 x4 and NVMe 1.3 is needed; a SATA-only M.2 slot will not work.
