This key-shaped USB drive with a square head and round hole features an integrated metal construction. Crafted from high-strength stainless steel, it undergoes precision CNC machining and a brushed (or electroplated) finish. This not only provides scratch-resistant and corrosion-resistant properties but also showcases the minimalist aesthetic of industrial design through its matte (or mirror) metallic appearance.

The square head is ergonomically designed for a stable grip during insertion and removal. The circular keyring hole is compatible with standard keychain specifications, allowing it to be carried with your keys. This prevents loss while meeting the portable “grab-and-go” demand.

This USB flash drive features high-speed NAND flash memory chips and supports multiple capacity configurations ranging from 8GB to 128GB, allowing flexible selection based on data volume. Interface protocols are compatible with USB 2.0/USB 3.0 standards. The USB 3.0 version achieves sequential read speeds exceeding 100MB/s and sequential write speeds surpassing 30MB/s (actual speeds may vary based on device and environment), enabling efficient transfer of large files such as engineering drawings, video footage, and database backups.

In reliability testing, this USB drive passed rigorous environmental trials including vibration (10-2000Hz), drop (1.5-meter free fall), and extreme temperatures (-20°C to +70°C). It meets industrial-grade storage device environmental adaptability requirements and can be deployed in complex scenarios such as industrial automation production lines, outdoor surveying, and vehicle data logging.

Additionally, the laser etching process on metal surfaces enables customized production of corporate logos, product codes, or encrypted partitions. This not only provides branded carriers for business scenarios but also creates exclusive “one key, one password” storage solutions for industry users, delivering dual value in both data security and brand promotion.
