Dual-connector USB 3.2 Gen 2 drive

The Kingston DataTraveler microDuo 3C provides 128GB of portable storage with both USB Type-C and USB Type-A connectors on a single device. It is designed for users who move files between modern smartphones, tablets, laptops and desktop PCs without carrying separate adapters. The rotating metal cap protects the reversible Type-C plug when not in use.

USB 3.2 Gen 2 interface limits

The drive uses the USB 3.2 Gen 2 standard for a maximum read speed of 200MB/s, allowing roughly 1000 high-resolution photos to be transferred in under a minute. Write speeds are lower and vary with the host controller, file sizes and thermal conditions, so sustained large-file copies will not maintain the peak read figure. Performance also drops to the host port's maximum if connected to an older USB 3.2 Gen 1 or USB 2.0 socket.

Check host ports and OTG support

Before ordering, verify that your mobile device supports USB On-The-Go and has either a USB Type-C or Type-A port compatible with the drive's connectors. Some phones require OTG to be enabled in settings before the drive is recognised. Ensure the host system's USB port can supply sufficient power for the drive to operate reliably during large transfers.

Questions about this item

Should I choose the 128GB or 256GB version of this DataTraveler microDuo 3C?

The 128GB model fits the stated capacity; a 256GB option is mentioned as a range maximum but this specific MPN is the 128GB drive.

What does the 200MB/s read speed mean when I plug the drive into my laptop?

It indicates the peak sequential read rate under USB 3.2 Gen 1; real-world throughput will be lower and depends on the host controller, file sizes and system load.

The spec says USB 3.2 Gen 2 but the description cites USB 3.2 Gen 1 — which standard actually limits the transfer rate?

The drive operates at USB 3.2 Gen 1 speeds, capping the practical transfer rate at the 200MB/s read figure quoted for that generation.
