Dual-connector flash drive for Android and PC

The SanDisk Ultra Dual Drive m3.0 combines a micro-USB plug for OTG-enabled Android phones and a USB 3.0 plug for laptops or desktops in a single 64 GB stick. It is built for users who need to offload photos, videos and contacts from a phone without cloud access and then read the same files on a computer.

Retractable design and Memory Zone app

A sliding mechanism hides whichever connector is not in use, protecting both ports from damage and pocket lint. The free SanDisk Memory Zone application from Google Play adds automatic camera-roll backup, contact export and a file browser that can move or delete content directly on the drive.

Plug-and-play on most devices

No driver installation is required on Windows, macOS or Android; the drive appears as mass storage once inserted. The micro-USB end only works on devices that support USB On-The-Go, so phones lacking OTG cannot use it. USB 3.0 speeds fall back to USB 2.0 rates when connected to older ports.

商品問答

Will the retractable mechanism or dual connectors wear out with daily insertion and removal?

The drive uses a retractable design that covers both the micro-USB and USB 3.0 connectors when not in use, protecting the contacts from physical wear during daily carry.

What transfer bottleneck appears first when moving large video files continuously?

The USB 3.0 interface caps sustained reads at up to 150 MB/s, so the controller and NAND become the limiting factor once that ceiling is reached.

Does the drive get hot or draw enough power to throttle during all-day backups?

With no moving parts and a 0.01 lb flash-memory design, it stays cool and draws only standard USB bus power, so thermal throttling does not occur.
