256GB Ultra Dual USB 3.1 Type-C

The SanDisk Ultra Dual Drive SDDDC2-256G-G46 provides 256GB of storage in a compact flash drive. It features a reversible USB Type-C connector and a traditional USB connector. The retractable design protects both interfaces when not in use. Read speeds reach up to 150MB/s for quick file access.

Android users needing direct phone backup

This drive suits anyone moving photos, videos or documents between USB Type-C phones, tablets and computers without a cable. It frees up space on Android devices instantly. Buyers who require higher write performance for large video recording should look at something else. Users needing hardware encryption or rugged water resistance will not find those features here.

USB 3.1 Gen 1 interface with dual connectors

The single specification that decides compatibility is the USB 3.1 Gen 1 interface combined with both Type-C and Type-A plugs. Your devices must support USB On-The-Go for direct smartphone transfers. The drive draws power from the host port and requires no external supply. Capacity is fixed at 256GB with no expansion option.

Questions about this item

What does the USB 3.1 Gen 1 interface cap the read speed at in practice?

The drive uses USB 3.1 Gen 1, which supports up to 150 MB/s read speed on compatible ports.

What physical space does the retractable dual-connector design need to fit?

It measures 0.37" x 0.79" x 1.50" and weighs 0.02 lb, so it fits standard USB-A and USB-C ports side by side.

How do I install the drive on an Android phone, and what step do people miss?

Plug the USB-C end into the phone, allow file access in the prompt, then use the file manager to move data; skipping the permission prompt is the common mistake.

New to this? Buying memory and SSDs with crypto — what to check, what it costs to pay, and what is never asked for.
