Overview
This SanDisk Ultra Dual Drive Go pairs a USB-C plug with a USB-A plug on one 64GB body, so a single drive can move files between a USB-C phone or Mac and an older USB-A laptop without carrying an adapter.
SanDisk rates it at up to 150MB/s read over USB 3.1 Gen 1, and buyers who ran their own benchmarks found it holds close to that number rather than falling short of the spec sheet. The SanDisk Memory Zone app adds automatic photo backup from a phone, and the whole thing is small enough that several reviewers compare it to a AAA battery in size.
- Dual USB Type-C and Type-A connectors in one drive
- Rated up to 150MB/s USB 3.1 read speed
- SanDisk Memory Zone app for automatic photo backup
- 64GB capacity in a keychain-sized body
Who it's for
It suits anyone who regularly shuttles files between a USB-C phone or tablet and a USB-A desktop or laptop and wants to skip carrying an adapter. It is a weaker fit for someone who wants a drive tough enough to survive being tossed loose in a bag or backpack.
What buyers say
From Amazon customer reviews.
Buyers consistently praise how easily it moves files between an Android or USB-C phone and a laptop or desktop without adapters, and more than one confirmed the rated read speed with their own benchmark tools. The most common complaint is the size itself: several reviewers warn it is easy to lose unless kept on a keychain, and one flagged the plastic body as feeling cheap even while still recommending the drive overall.
Strengths and trade-offs
Drawn from this product's published specifications.
- Reversible USB-C and USB-A ends, no adapter
- Read speeds close to the rated 150MB/s
- Lightweight and small enough for a keychain
- Works as an OTG drive on Android phones
- Plastic housing feels less rugged than metal drives
- Small size makes it easy to misplace
- Write speeds lag well behind read speeds
Performance notes
Reviewers who benchmarked the drive with tools like CrystalDiskMark clocked read speeds in line with SanDisk's 150MB/s rating, with write speeds noticeably lower, which is typical for this class of drive. It also works as an OTG drive on Android phones, and one reviewer ran it well enough to boot a Linux Mint session directly from it.
