512GB USB 3.0 Flash Drive

The SanDisk Ultra SDCZ48-512G-G46 is a 512GB USB 3.0 flash drive with a Type-A connector. It offers read speeds up to 130MB/s and write speeds of 40 MB per second.

Suits users needing portable high-capacity storage

This drive suits users who need to move large files quickly between devices with USB-A ports. The hardware encryption helps protect sensitive documents and media. It is backward compatible with USB 2.0 ports. Buyers who require a USB-C connector or faster write performance for heavy workloads should look at something else.

Fits any system with a USB-A port

The drive plugs directly into any USB-A port without extra cables or power. It works with Windows and macOS for drag-and-drop file transfers. The SanDisk SecureAccess software enables password-protected folders. Its small form factor leaves adjacent ports free and adds negligible weight to a laptop bag or keychain.
