High-capacity portable storage

The SanDisk Ultra flash drive provides 1TB of storage with USB 3.2 Gen 1 connectivity and a Type A connector. It delivers read speeds up to 130MB/s for transferring large media libraries, presentations, and graphic files. The lightweight black casing makes it easy to carry in a pocket or bag.

Included encryption software

The drive features 128-bit AES encryption to protect private files with password security. This software-based feature secures sensitive documents, photos, and videos without requiring additional hardware or an internet connection for access.

Host port and performance expectations

Verify that your device has a USB Type A port to use this connector directly. Read speeds of up to 130MB/s are achievable on USB 3.2 Gen 1 or 3.0 ports, while USB 2.0 ports will operate at significantly lower transfer rates.

Questions about this item

Will the 128-bit AES encryption or the USB Type-A connector wear out and need replacement?

The drive has no moving parts and the 128-bit AES encryption is handled by the controller firmware, so neither the security feature nor the USB Type-A connector requires scheduled replacement.

What limit appears first when writing large files continuously at the 130MB/s read speed?

Sustained write speeds are lower than the 130MB/s read figure, so the write throughput ceiling will be reached before the read limit during long transfers.

How much heat or power draw should I expect when the drive runs all day on USB 3.2 Gen 1?

The lightweight design draws power only from the USB 3.2 Gen 1 port with no external adapter, and typical flash-drive operation stays cool enough for continuous daily use.
