2TB Dual-Drive Capacity

The SanDisk Ultra Dual Drive Go provides 2TB of portable storage in a single flash drive that carries both a USB Type-C and a USB Type-A connector. It is built for photographers, students and mobile professionals who need to move large libraries between smartphones, tablets, Macs and PCs without relying on cloud sync. The swivel metal casing protects both connectors when the drive is tossed in a bag or clipped to a keyring.

USB 3.2 Gen 1 Twin Interface

The drive plugs directly into USB Type-C phones such as the iPhone 15 series, Android handsets, iPad Pro models and modern laptops, then flips to the classic Type-A port for desktop PCs and older hardware. No adapters, cables or external power are required, so a transfer session can start the moment the drive is inserted. The reversible Type-C plug removes orientation frustration during quick offloads in the field.

400 MB/s Read Headroom

Sequential reads reach up to 400 MB/s over USB 3.2 Gen 1, letting you pull multi-gigabyte video folders or RAW photo bursts to a workstation in seconds rather than minutes. Write speeds are lower, so ingesting fresh footage directly onto the drive will take noticeably longer than reading it back. The 2TB volume handles months of 4K clips or thousands of high-resolution images before a cleanup is needed.

Questions about this item

Does the 400 MB/s peak speed drop once the drive fills up or runs hot?

The 400 MB/s figure is the maximum read speed under ideal conditions; sustained write speeds will be lower and can vary with file size, temperature and how full the 2 TB capacity is.

Does the tiny 0.01 lb body get warm or draw noticeable power during all-day transfers?

The metal swivel housing dissipates heat from the USB 3.2 Gen 1 controller, so the drive stays comfortable to touch and draws only standard bus power with no fan or extra cable needed.

Will my phone need the SanDisk Memory Zone app installed before the Type-C connector works?

The Type-C and Type-A connectors work immediately for manual drag-and-drop on any host that supports USB mass storage; the app is only required for the automatic photo and contact backup feature.
