Compact plug-and-stay storage

The SanDisk Ultra Fit SDCZ430-016G-G46 is a 16GB USB 3.1 (Gen 1) flash drive with a Type A connector. Its low-profile black housing measures 0.20" x 0.56" x 1.17" and weighs 0.05 oz, allowing it to remain inserted in laptops, tablets, TVs, gaming consoles or car audio systems without protruding.

Sustained transfer behaviour

Read speeds reach up to 130MB/s while write performance is rated up to 15 times faster than standard USB 2.0 drives. The manufacturer notes a full-length movie can move to the drive in less than 30 seconds. Actual throughput will vary with the host controller, file sizes and thermal limits during extended sessions.

USB 3.1 Gen 1 practical limits

The drive operates within the USB 3.1 Gen 1 specification, capping the theoretical bus bandwidth at 5 Gbps. Real-world speeds depend on the host port implementation, cable quality and system overhead. 128-bit AES encryption via SanDisk SecureAccess software adds a processing layer for secured files.

Questions about this item

Does the USB 3.1 Gen 1 interface draw much power or get hot when left plugged into a laptop all day?

The Ultra Fit uses a low-power USB 3.1 Gen 1 controller and its tiny 0.20" x 0.56" x 1.17" body has no moving parts, so it stays cool and draws minimal current during continuous use.

What must my device already have to use the Type A connector and 128-bit AES encryption?

You need a free USB Type A port and the ability to run the SanDisk SecureAccess software to create the encrypted vault.

Will the 130 MB/s read speed still work if I plug it into an older USB 2.0 port on my TV or car stereo?

It will work but fall back to USB 2.0 speeds; the 130 MB/s read rate and 15× faster write claim require a USB 3.1 Gen 1 or 3.2 port.
