SanDisk 128GB Ultra Dual Drive USB Type-C Pack of 4 - Fast Transfer

In this review the SanDisk 128GB Ultra Dual Drive USB Type-C (pack of 4) is assessed for anyone who needs quick mobile storage and cross-device file transfers. The single biggest reason to buy is its combination of a reversible USB Type-C connector and a traditional USB-A connector in a retractable design, which makes moving photos, videos and documents between Android phones, tablets and computers straightforward. For users who need to free up space on an Android device or shuttle large files between systems without adapters, this pack delivers simple, portable capacity.

Key Features

• Dual connectors: The retractable design provides both a reversible USB Type-C connector and a traditional USB-A connector so the drive works with newer phones and older computers without extra adapters.
• High read speed: USB 3.1 performance of up to 150MB/s read speeds lets users open and transfer large files faster when connected to a USB 3.1 or USB 3.0 host.
• Mobile backup: The drive frees up space on Android smartphones by offloading photos and videos, provided the mobile device supports USB Type-C and On-The-Go (OTG).
• Manage files: Support for the SanDisk Memory Zone app for Android makes it easier to browse, move and back up content from the phone to the drive.
• Multi-pack value: The pack of four is convenient for households, teams, or creating backups and sharing drives without buying multiples separately.

Who It's For

This USB drive pack is best for Android users with a USB Type-C port and OTG support who want a simple way to free up phone storage and carry extra media. It also fits home or office users who need a handful of portable backups to swap between Windows and Mac computers using the USB-A port.

Power users who require the absolute fastest sustained write performance for large video projects should look elsewhere for purpose-built NVMe pocket drives. Likewise, users who need encryption hardware or enterprise-grade ruggedness may prefer a specialized model.
