Compact USB-C Flash Drive

The SanDisk Extreme Fit SDCZ530-128G-G46 is a 128GB USB 3.2 Gen 1 flash drive with a fixed USB Type-C connector. Its low-profile design measures 0.73" x 0.54" x 0.63" and weighs 0.006 lb, allowing it to sit flush with laptops, tablets and other USB-C devices for plug-and-stay storage expansion.

Suited for portable file access.

This drive suits users who want compact, semi-permanent storage for documents, photos and videos on USB-C equipped computers and tablets. It is less appropriate for workflows that demand sustained write performance or for systems that only offer USB Type-A ports without a separate adapter.

400MB/s peak read speed over USB 3.2 Gen 1

The headline specification is a maximum read speed of 400MB/s, delivered through the USB 3.2 Gen 1 5 Gbps interface. Buyers should confirm their host device supports USB 3.2 Gen 1 or faster over Type-C to achieve the quoted transfer rate.

Questions about this item

Does the 128GB SDCZ530-128G-G46 include any cables or adapters in the box?

The drive is a single USB-C unit with no extra cables or adapters supplied; it plugs directly into a USB-C port.

Why choose the 128GB version instead of a larger capacity?

The 128GB model still delivers up to 400MB/s read speed over USB 3.2 Gen 1 while costing less than higher-capacity variants.

What does the 400MB/s read figure mean when copying files to my laptop?

It is the maximum sequential read speed the 128GB drive can reach over USB 3.2 Gen 1; real-world transfers will be lower depending on file types and host performance.
