Product Overview
The Dahua 64GB USB 3.1 Metallic Micro Flash Drive (DHI-USB-U166-31-64G) is an ultra-compact, high-speed USB flash drive designed for convenient data storage and fast file transfers. Featuring a USB 3.2 Gen 1 (USB 3.1 Gen 1) interface and 64GB storage capacity, it delivers reliable performance for storing documents, photos, videos, music, presentations, and backups. Its miniature metallic design makes it an excellent choice for laptops, desktops, smart TVs, gaming consoles, car infotainment systems, and other USB-enabled devices where a low-profile drive is preferred.
Equipped with a USB 3.2 Gen 1 Type-A interface, the flash drive provides read speeds of up to 150MB/s and write speeds of up to 100MB/s (depending on the host device and file type), enabling significantly faster file transfers than traditional USB 2.0 drives. It is also backward compatible with USB 2.0, ensuring seamless use with both modern and older computers and devices.
The 64GB storage capacity provides ample room for everyday digital content, including office documents, HD videos, photos, software installers, and multimedia libraries. The drive is formatted with the exFAT file system, allowing support for large files over 4GB while maintaining compatibility across multiple operating systems.
Its metallic micro housing offers a durable, shock-resistant, and anti-drop design while remaining extremely lightweight at approximately 2.2g. The compact form factor protrudes only slightly from the USB port, making it ideal for devices where the drive may remain connected for extended periods, such as car stereos, smart TVs, or laptops.
The flash drive supports Windows, macOS, Linux, and Android (OTG-compatible devices) with true plug-and-play functionality, requiring no additional drivers. Whether used for work, study, entertainment, or backups, it offers dependable everyday performance in a compact package.
