Compact high-speed storage

The WDT Ultra Fit 64GB USB 3.1 Flash Drive adds 64 GB of portable capacity to laptops, tablets, TVs, gaming consoles or car audio systems. Its low-profile plug-and-stay form factor remains barely visible once inserted. The drive targets users who want permanent extra space without a protruding dongle.

Encrypted privacy folder included

SanDisk Secure Access software creates a password-protected vault using 128-bit AES encryption on the drive itself. Sensitive documents stay private even if the stick is lost. No separate installation media is required; the software travels with the device.

USB 3.1 interface with fast reads

A 130 MB/s read speed moves a full-length movie to the drive in under 30 seconds, roughly 15 times quicker than USB 2.0. The standard Type-A connector fits any compatible port without adapters. The tiny housing leaves adjacent ports unobstructed on crowded hubs.

Questions about this item

Will the plastic casing or USB 3.1 connector need replacement after daily carry?

The Ultra Fit's low-profile casing is built to stay inserted in a port, so the connector and shell see no repeated insertion wear under normal use.

What thermal limit appears first when the drive writes at 130 MB/s for long periods?

Sustained writes at 130 MB/s raise the metal shield temperature until the controller throttles speed to protect the NAND, which is the first limit reached.

How much power does the 64 GB Ultra Fit draw when plugged into a TV USB port all day?

The drive operates from the host port's 5 V supply with no external adapter, and idle power drops to a minimal level when no transfers are active.
