Silicon Power Blaze B50 256GB USB 3.2 Gen 1 Flash Drive, Capless Retractable, Carbon Fibre Texture, Black

The Silicon Power Blaze B50 256GB (SP256GBUF3B50V1K) is a black USB 3.2 Gen 1 flash drive with a capless, thumb-slide retractable connector and a carbon-fibre-textured body, for everyday users who want plenty of space and a design with no cap to lose.

The textured surface is made to resist scratches, dust and fingerprints, and the connector retracts into the body when not in use. Silicon Power does not publish speed figures for the 256GB version, so we do not quote any; the USB 3.2 Gen 1 interface itself runs at up to 5 Gbps.

• 1 × Silicon Power Blaze B50 256GB USB flash drive
• Retail packaging

• 256GB comfortably holds a large photo library, a season of video or a full laptop documents folder.
• Compatibility is broad: Windows 11 back to XP, macOS 10.3 or later, Linux 2.6 or later, Android 6.0 or later and iOS 13 or later (phones and iPads need an adapter).
• Usable capacity shown in Windows or macOS is lower than the label: manufacturers count 1 GB as 1,000,000,000 bytes, operating systems count in binary units, and the file system takes a small share.
• Real-world speed depends on the port, the computer and the files: one large video copies much faster than thousands of small photos or documents.
• Always use Eject or Safely Remove before pulling the drive out; unplugging during a write is the most common cause of a corrupted stick.

• No hardware encryption or password protection; choose an encrypted drive for sensitive data.
• It does not plug straight into USB-C-only laptops, tablets or phones; you need a USB-C to USB-A adapter (an OTG adapter for phones).
• It is not a backup on its own: flash drives get lost and can fail, so keep a second copy of anything important.
• It is not an external SSD; for large daily transfers or running applications from the drive, an external SSD is the right tool.
