What's the difference between USB 2.0 and USB 3.0 flash drives?
USB 3.0 drives can transfer data up to 10x faster than USB 2.0. A USB 3.0 drive can achieve 100-400MB/s read speeds, while USB 2.0 maxes out at about 30MB/s. Always choose USB 3.0 or newer for better performance, especially with larger files.
Should I buy a USB-A or USB-C flash drive?
USB-A is compatible with most computers and devices. USB-C is increasingly common on newer laptops, tablets, and smartphones. Consider a dual-connector drive (USB-A + USB-C) for maximum flexibility across all your devices.
How long do USB flash drives last?
USB flash drives can last 10+ years with normal use. They're rated for around 10,000-100,000 write/erase cycles depending on quality. For important data, always maintain backups elsewhere, as physical damage or loss is a bigger risk than wear.
Should I buy a USB flash drive or a portable SSD?
For everyday file transfers under 128GB, a USB flash drive is cheaper and more pocket-friendly. For larger storage needs (500GB+) or fast transfers, a portable SSD offers much better speeds and reliability. Choose a USB drive for convenience and portability, or an SSD for performance.
