Flash drive, microSD, or portable SSD?
- Flash drives are for quick file moves between computers. Pick one that’s rated for high write speeds if you copy large files often.
- microSD cards go in handheld consoles, drones, action cams, and phones. Look for A2 for apps and V30 or higher for 4K video.
- Portable SSDs are for backups, big photo and video libraries, and editing directly from the drive.
Match the port
A drive only runs as fast as the port you plug it into. The Samsung T9 needs USB 3.2 Gen 2x2 to reach 2,000 MB/s. On a regular USB 3.2 Gen 2 port it runs at roughly T7 Shield speeds.
Don’t skip backups
Portable drives get lost and dropped. Keep anything important in at least two places.
