Silicon Power Blaze B20 Chiavetta USB 64GB USB 3.2 Gen 1, USB-A retrattile, Nero

At the office, a marketing coordinator needs to hand off a 4K product demo video to the AV team before the afternoon presentation. The Silicon Power Blaze B20 64GB flash drive slips out of a pocket, the retractable USB-A connector slides forward with a satisfying click, and the file transfers at up to 90 MB/s — no cap to lose, no delay. Back at the desk, the same drive carries the final presentation deck, ready for the boardroom PC or a borrowed laptop running Windows, macOS, or Linux.

Why choose it

The Blaze B20 removes the weakest point of most flash drives — the cap. Its retractable connector protects the USB plug when not in use and eliminates the risk of losing a cap in a bag or drawer. Despite the capless design, it remains slim and pocket-friendly, while the LED indicator gives a clear signal during data transfers. With USB 3.2 Gen 1 speeds, moving large files is quick, and full backward compatibility means it works with older USB 2.0 ports found on many office PCs and car stereos.

Ideal use cases

• Transferring high-resolution photos, videos, and presentations between workstations
• Carrying portable software or bootable OS installers for IT support
• Expanding storage for media playback on smart TVs, car audio systems, or game consoles with USB-A ports
• Everyday backup of documents, spreadsheets, and school projects

Good to know

The drive is plug-and-play with no drivers required on modern operating systems. A free SP Widget software download is available from Silicon Power for file encryption and backup features. The plastic housing is robust enough for daily carry, and the limited lifetime warranty provides long-term peace of mind. Actual transfer speeds may vary depending on host device, file type, and USB port version.
