Silicon Power Blaze B20 32GB USB Flash Drive, USB 3.2 Gen 1 Type-A, Retractable Diamond-Cut Design, Matte Black

The Silicon Power Blaze B20 32GB (SP032GBUF3B20V1K) is a USB 3.2 Gen 1 flash drive with a USB Type-A plug for carrying documents, photos, installers and backups between computers at the office and at home.

Instead of a cap, the USB connector is pushed out with your thumb and retracts back into the matte, diamond-cut case after use. The finish hides fingerprints and scratches better than glossy drives, and a strap hole lets you keep it on a key ring. It is an everyday file-carrying drive, not a speed-rated or rugged model.

• 1 × Silicon Power Blaze B20 32GB USB flash drive (Matte black)
• SP Widget software is offered as a free download from Silicon Power — there is no disc in the package
• Silicon Power does not list a cable, adapter or lanyard in the package

• Usable space: a 32GB drive shows about 29.8 GB in Windows — operating systems count in binary units and the file system takes a little space, so this is normal, not a fault.
• In a USB 3.x port (often blue or marked SS) the drive uses the 5 Gbps USB 3.2 Gen 1 interface; in a USB 2.0 port it still works, at USB 2.0 speed.
• Silicon Power does not quote a read/write MB/s figure for this model, so real speed depends on the host port and on file size — many small files always copy slower than one large file.
• If the drive is formatted FAT32, single files over 4 GB will not copy. Reformat it to exFAT (readable and writable on Windows and macOS) before copying large videos or ISO images.
• Always use Eject / Safely Remove before unplugging, especially right after copying — unplugging during a write is the most common cause of corrupted files on any flash drive.

• There is no USB-C plug — on USB-C-only laptops, tablets and phones you need a USB-C to USB-A adapter, or a dual drive such as the Mobile C31.
• It does not become faster than USB 2.0 speed when plugged into a USB 2.0 port or hub.
• It is not built for continuous 24/7 writing (dashcams, CCTV recorders, servers, running an OS from it) — use an SSD or a high-endurance card for that.
• macOS reads but cannot write NTFS-formatted drives without extra software — use exFAT if you move files between Windows and Mac.
• A single flash drive is not a backup on its own: keep a second copy of anything you cannot afford to lose.
