USB 3.0/3.1/3.2 – High-speed interfaces (up to 10 Gbps)
-
USB Type-C – Reversible connector with higher speed and power delivery
Controller Chip
This chip manages data flow between the flash memory and the USB interface. It determines how fast the device can read and write, and it also handles functions like wear leveling and error correction.
Types of USB Storage Devices
Standard USB Flash Drives
These are the most common type, used for transferring and backing up files, installing software, and storing media.
USB OTG (On-The-Go) Drives
Designed to connect directly to smartphones and tablets, OTG drives usually feature dual connectors (USB-A and Micro-USB or USB-C), enabling file sharing between mobile and desktop devices.
Secure USB Drives
Security-focused USB drives offer features like password protection, fingerprint authentication, and hardware-based encryption, making them ideal for handling sensitive data in IT hardware and enterprise environments.
High-Capacity and SSD-Based USB Drives
Some USB drives use solid-state technology to offer faster speeds and higher reliability, often bridging the gap between traditional USB drives and external SSDs.
