Dual USB-C and USB-A connector

The SanDisk Ultra Dual Drive SDDDC2-128G-G46 provides 128GB of storage in a flash drive fitted with both a reversible USB Type-C plug and a traditional USB Type-A plug. It lets users move files between modern smartphones, tablets and computers without needing an adapter or cable.

No active cooling and bus-powered operation

The drive has no fan or moving parts, so it runs silently and draws power directly from the host port. Its compact plastic body measures 0.37" x 0.79" x 1.50" and weighs 0.02 lb, adding negligible bulk to a keyring or pocket.

Sustained transfers limited by USB 3.1 Gen 1

Sequential reads reach up to 150MB/s while writes are slower, so very large file batches will take proportionally longer than a short burst. The retractable design protects both connectors when the drive is not in use.

Questions about this item

How do I connect the reversible USB Type-C end to my phone without forcing it?

Align the oval Type-C plug with the port and insert it either way up — the reversible design removes the need to check orientation, which is the step most people hesitate on.

What part of the SDDDC2-128G-G46 is most likely to wear out first with daily carry?

The retractable slider mechanism that shields the USB Type-A and Type-C connectors can loosen after repeated cycles, so keep the track free of grit.

At what point does sustained write speed drop below the 150 MB/s read rating on this 128 GB drive?

Continuous large-file writes will hit the flash memory's lower write throughput well before the 150 MB/s read ceiling, so expect slower sustained write performance.

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