Frequently Asked Questions
What USB drive speed do I need?
USB 3.0/3.1/3.2 drives (100–400 MB/s read) are fast enough for any file transfer task. USB 2.0 drives (25 MB/s max) feel slow for large files. For transferring a 10GB file: USB 3.0 takes ~1 minute vs 7+ minutes on USB 2.0. Look for USB 3.2 Gen 1 (5Gbps) as a minimum for any meaningful use.
How much storage do I need on a USB drive?
For simple file transport: 32–64GB handles documents, photos, and most software installers. For OS bootable drives: 32GB minimum. For full system backups: 256GB+. For storing a media collection: 256GB–1TB.
