About products and suppliers

A USB flash drive is a portable device using flash memory for storage. It's lightweight and accessible through a computer. A flash drive can store data backups, files, applications, and settings. Moreover, it can run diagnostics or launch an operating system if it's a bootable USB. A USB drive supports several operating systems, such as Linux, MacOS, and Microsoft windows. Today, it can have a capacity of up to 1 terabyte. However, expect its future ability to reach two terabytes. A thumb drive's life expectancy depends on the number of times a user writes and deletes data.

What are the specifications of a USB flash drive?

A memory stick has three specifications – USB 1.0, 2.0, and 3.0. Each spec is faster than the previous one regarding data transfer rates. For example, USB 1.0 had up to 12 Mbps data transfer rate, while USB 2.0 had up to 480 Mbps. Lastly, USB 3.0 had up to 5 Gbps.

What are the benefits and drawbacks of a USB flash drive?

USB sticks have immovable components and use little power. They're lightweight and tiny and usually have rubber or plastic exteriors. Fortunately, USB-C memory sticks are robust enough to withstand dust, scratches, and mechanical shocks. In addition, they're waterproof and can retain data for years, even if unplugged from the computer. Therefore, a USB-C flash drive is convenient for backup or data transfer from one computer to another.

A flash drive for a phone doesn't require an external power supply or battery. It's platform-independent and doesn't need rebooting. A pen drive can be password-protected and have downloadable drivers to be compatible with previous systems, not requiring USB ports. However, its limitation lies in the number of writes and delete cycles before it lies. In addition, data leakage and a security breach can be an issue because it's portable. Regarding security breaches, a potential solution is to encrypt the drive and perform a routine scan.
