SANDISK ULTRA DUAL DRIVE M3.0, 64GB (130MB/s),SDDD3-064G

SanDisk Ultra Dual Drive m3.0 64GB (SDDD3-064G-G46)

The SanDisk Ultra Dual Drive m3.0 64GB is a dual-connector flash drive built for OTG-enabled Android smartphones and tablets alongside standard computers. It pairs a micro-USB connector with a USB 3.0 connector in a single retractable body, delivering 64GB of storage, transfer speeds of up to 130MB/s, and a 5-year limited warranty from SanDisk. Since the drive is automatically detected when plugged into an OTG-compatible Android device, there’s no manual setup required to start moving files. It also supports Windows 7, Windows 8, Windows 10, and Mac OS X v10.9 and higher, so the same drive works across phone and desktop environments. Measuring 0.46″ x 1″ x 1.19″ and weighing 5 grams, it offers double the storage of the 32GB model while keeping the same compact, pocket-friendly footprint.

Key Features

• 64GB storage capacity — double the space of the entry-level 32GB model
• Dual micro-USB and USB 3.0 connectors — built for Android OTG devices and computers alike
• Up to 130MB/s transfer speeds — solid performance over the USB 3.0 connector
• Retractable design — protects connectors without needing a separate cap
• 5-Year Limited Warranty — SanDisk’s extended coverage on this model
