Ultra-compact 64GB USB 3.1 drive

The SanDisk Ultra Fit is a low-profile flash drive with 64GB of storage and a USB 3.1 interface rated at up to 130MB/s read speed. Its tiny black housing stays almost flush with the port, making it suited for laptops, car stereos or any device where a protruding stick would be awkward. The drive is supplied new and ready to use.

No bundled software or accessories

The package contains only the flash drive itself; there is no included encryption utility, backup application or physical accessory such as a cap or lanyard. This keeps the form factor minimal but means any password protection or automatic sync must be provided by the operating system or third-party tools you install separately.

Suits users wanting discreet portable storage

It works well for anyone who needs 64GB of extra space that can stay permanently plugged into a USB-A socket without snagging. Buyers who require faster write performance, hardware encryption, a USB-C connector or capacities above 64GB should consider other models.

Questions about this item

Will the USB connector on the SDCZ430-064G wear out with repeated insertion?

The USB 3.1 connector is rated for thousands of mating cycles, so normal daily use will not wear it out during the drive's practical lifespan.

What limits sustained write speed on the 64GB Ultra Fit during long transfers?

The compact metal body has limited surface area for heat dissipation, so thermal throttling will reduce write speeds once the internal temperature rises.

How much power does the 130MB/s Ultra Fit draw when plugged in all day?

It draws power only during active reads or writes; idle consumption is negligible and it produces no audible noise.
