What this drive is and who it suits

The SanDisk Ultra 128GB USB 3.0 flash drive delivers read speeds up to 130MB/s for moving large files quickly. It includes SanDisk SecureAccess software for 128-bit AES encryption and password protection. The compact Type-A design suits students, office workers and anyone needing portable, encrypted storage without an internet connection.

Check your ports and speed needs

Verify your computer has a USB 3.0 or newer Type-A port to reach the advertised transfer rate; the drive works with USB 2.0 ports at reduced speed. No driver installation is required on modern operating systems. Ensure you have a free port and that 128GB capacity matches the volume of media, documents and backups you plan to carry.

Who should buy this and who should not

This drive suits users who want fast, hardware-encrypted portable storage in a small form factor. Buyers who need more than 128GB of capacity should consider larger models. Users requiring a USB Type-C connector or ruggedised housing for extreme environments will need a different product.

Questions about this item

Does the SanDisk Ultra SDCZ48-128G-U46 come with any cables or adapters, or is the drive the only item in the box?

The SanDisk Ultra SDCZ48-128G-U46 is a standalone USB Type-A flash drive. No cables, adapters or additional accessories are included in the packaging.

Should I choose the 128GB version or a different capacity for storing large video files and backups?

The 128GB capacity holds high-resolution photos, MP3s, videos, presentations and graphic files. Larger capacities up to 1TB are available in the same series if you need more space.

What does the 130MB/s read speed mean when I am copying files to my laptop?

The 130MB/s figure is the maximum read speed under ideal conditions. Real-world transfer rates depend on your laptop's USB port, file types and system overhead, so actual speeds will be lower.
