KINGMAX PQ4442 M.2 2242 SSD Launches with 5,000MB/s Read Speeds

KINGMAX has expanded its storage options for compact computers with the PQ4442 series, a new solid-state drive designed specifically for small form factor systems. This release matters because it provides a PCIe 4.0 capable storage solution in the tiny M.2 2242 footprint, a size often restricted to slower or lower-capacity drives. Buyers building mini PCs or upgrading laptops with limited internal space now have a high-performance alternative that fits without requiring chassis modifications.

New drive fits high performance into compact chassis designs

The PQ4442 series utilizes an M.2 2242 form factor, measuring just 22mm by 42mm and weighing only 7.5 grams. It connects via a PCIe 4.0 x4 NVMe interface, ensuring compatibility with modern motherboards that support this high-speed standard. The drive relies on 3D NAND flash memory to deliver storage densities of 500GB, 1TB, and 2TB within this constrained physical envelope.

Specifications

• Form Factor: M.2 2242
• Interface: PCIe 4.0 x4 NVMe
• Max Sequential Read: 5,000MB/s
• Max Sequential Write: 4,400MB/s
• Warranty: 3 years

Performance figures for the PQ4442 peak at 5,000MB/s for sequential reads and 4,400MB/s for sequential writes. Random access operations reach up to 400,000 IOPS for reads and 500,000 IOPS for writes, which supports responsive multitasking in tight spaces. The 2TB model consumes up to 5.2W of power, a figure that helps manage thermal output in enclosed cases where airflow is limited.

Reliability metrics include a mean time between failures of 2,000,000 hours across the lineup. Total terabytes written endurance scales with capacity, offering 280TBW for the 500GB model, 560TBW for the 1TB version, and 960TBW for the 2TB unit. KINGMAX backs the PQ4442 series with a three-year warranty, providing a standard protection period for enterprise or heavy consumer use.

The company announced the PQ4442 series on June 26, 2026. Current specifications confirm the technical capabilities and physical dimensions of the new storage hardware. No pricing or specific regional availability details have been released at this time.
