Ultra-compact plug-and-stay drive

The SanDisk Ultra Fit 1TB USB 3.2 Gen 1 Flash Drive adds a full terabyte of storage through a tiny Type A connector that barely protrudes from the port. It is designed for users who want permanent extra capacity on a laptop, game console or in-car audio system without a dangling cable.

Downloadable 128-bit AES encryption

Password protection software secures files on the drive using 128-bit AES encryption. The utility runs on Windows 10 or later and macOS 10.9 or later, but it must be downloaded from the SanDisk website before the feature can be used.

Up to 400MB/s read and 60MB/s write

Sequential reads reach 400MB/s on a USB 3.2 Gen 1 or USB 3.0 host, letting a 1.2GB movie transfer in under 30 seconds. Writes are limited to 60MB/s, so large batch backups take noticeably longer than the initial fill.

Questions about this item

Does the 1 TB SanDisk Ultra Fit drive have any moving parts that could fail?

No, it is a solid-state USB flash drive with no moving parts, so there are no mechanical components to wear out or replace.

Will the 400 MB/s read speed hold steady during long transfers?

The 400 MB/s figure is a peak read speed from internal testing; sustained throughput will be lower and varies with the host device, file types and drive capacity.

How warm does the SDCZ430-1T00-G46 get when plugged in all day?

The compact metal body can become noticeably warm during continuous reads or writes because there is no active cooling, but it stays within normal operating limits for flash memory.
