SanDisk Ultra Fit 64GB USB 3.2 Gen 1 Flash Drive

Compact 64 GB USB 3.2 Gen 1 drive

This tiny SanDisk Ultra Fit flash drive adds 64 GB of portable storage to laptops, tablets, TVs, gaming consoles and in-car audio systems. Its plug-and-stay form factor protrudes very little, so it can remain inserted during transport or everyday use. The drive is backwards compatible with USB 3.0 and USB 2.0 ports for broad device support. No external power or drivers are required for basic operation.

Check port type and software needs

Verify that your host device offers a USB-A port; the drive uses a USB-A 3.2 Gen 1 male connector and will fall back to USB 3.0 or 2.0 speeds on older ports. The included 128-bit AES encryption and RescuePRO Deluxe recovery tools are downloadable Windows and Mac applications, so confirm your operating system can run them before relying on those features. Physical space around the port should allow the low-profile body to seat fully without blocking adjacent sockets.

Sustained transfer behaviour

Sequential read speeds reach up to 130 MB/s under ideal conditions, though prolonged large-file writes will typically settle below that peak as the controller manages thermal limits. The compact metal casing dissipates heat passively, so extended sessions may trigger throttling to protect the NAND. For intermittent file moves or media playback the drive maintains consistent responsiveness, while continuous archiving tasks will see reduced throughput after the initial burst.
