KINGMAX PQ4442 M.2 2242 PCIe Gen4x4 SSD Debuts – Gen4 Speed in a Small Form Factor, 2TB High Capacity for Professional Needs

KINGMAX, a well-known storage product supplier, launches the PQ4442 M.2 2242 PCIe NVMe Gen4x4 solid-state drive. As a Gen4 upgrade version, this series is designed for compact devices that have moved to PCIe 4.0 platforms, including high-performance ultra-thin notebooks and mini creator PCs. While maintaining the compact 22×42mm size, the PQ4442 boosts sequential read speeds to 5,000 MB/s and offers a 2TB high-capacity option in the 2242 form factor. Combined with up to 500K IOPS random write performance, it helps content creators and high-end gamers enjoy smoother 4K/8K asset processing and game loading within small chassis.

▍ 3D NAND + SLC Cache: Large Capacity Meets Small Size

The PQ4442 uses 3D NAND flash to achieve up to 2TB capacity in the compact 2242 size. Paired with SLC caching, it dynamically optimizes burst write performance. For instance, when creators edit 4K video projects on an ultra-thin notebook, frequently reading and writing hundreds of gigabytes of footage, the PQ4442 provides fast and relatively stable write responses, reducing wait times during rendering and export. For handheld gaming console users, the 2TB capacity is enough to install dozens of AAA titles while enjoying PCIe 4.0’s fast loading.

▍ LDPC ECC + Multiple Protections: Data Security and Long-Term Durability

To prevent read/write errors, the PQ4442 features built-in LDPC ECC (Low-Density Parity-Check) error correction, which detects and repairs erroneous data in real time, enhancing data integrity over long-term use. The SSD also supports TRIM commands, wear leveling, garbage collection, and NCQ commands with data shaping techniques, improving read/write efficiency and extending flash lifespan. For small workstations or industrial inspection equipment that require frequent reads/writes, these technologies reduce the risk of performance degradation under prolonged high-load writes, ensuring the long-term reliability of critical project data.

▍ Speed Leap: Up to 5,000 MB/s Read – Fully Unleashing PCIe 4.0 Advantages

The PQ4442 features a PCIe Gen4×4 interface, backward compatible with Gen3. Compared to PCIe Gen3 products, the PQ4442 offers nearly double the transfer bandwidth. In daily use, this means AAA game loading times drop from tens of seconds to just over ten seconds; scrubbing through 8K video timelines in applications becomes smoother; system and software installation, as well as large file compression/decompression, are significantly more efficient. For users installing the drive in small-form-factor devices, even with limited cooling space, the PQ4442’s power consumption is controlled within 5.2W (for the 2TB version), striking a balance between high-speed read/write and temperature control.

▍ Multiple Specifications for Flexible Choices

Meeting the diverse form-factor requirements of motherboards, laptops, gaming consoles, mobile devices, and embedded systems.
