Ultra-compact 128 GB USB 3.2 Gen 1 drive

The SanDisk Ultra Fit SDCZ430-128G-G46 is a tiny Type-A flash drive that adds 128 GB of storage to laptops, game consoles, in-car audio systems and other USB hosts.

Password protection and file recovery software

Downloadable software enables 128-bit AES encryption so you can password-protect sensitive files on the drive. RescuePRO Deluxe is also included to recover accidentally deleted files. These utilities add security and a safety net without requiring any hardware changes.

Questions about this item

Will the plastic housing or the Type-A connector wear out if I leave the drive plugged into my laptop permanently?

The drive uses a compact plug-and-stay design measuring 0.20" x 0.56" x 1.17" with a standard USB Type-A connector rated for typical insertion cycles; no user-serviceable parts exist inside.

Does the 400MB/s read speed hold steady when I copy a single large file that fills the 128GB capacity?

The quoted 400MB/s is a maximum read speed; sustained write throughput on large transfers will be lower and varies with file type, host controller and thermal conditions.

Does the tiny metal casing get hot enough to throttle speeds during an all-day backup?

The metal body acts as a heat spreader; under continuous heavy writes the controller may reduce performance to stay within safe operating temperatures.
