Speed, Capacity, and Connector
Storage capacity
The SanDisk 32GB Ultra Dual Drive offers double the storage of the 16GB Ultra Flair USB 3.0 Drive. You get 32GB of space on the Dual Drive, which is helpful for larger files or more photos. The Ultra Flair provides only 16GB. If you need to store more data without managing multiple drives, the 32GB option is the practical choice. The extra capacity helps you keep more videos or documents on hand without immediately needing external cloud storage or another physical drive.
Read speed
Speed matters when you move large files like movies or high-resolution photos. The SanDisk 32GB Ultra Dual Drive lists read speeds of up to 150MB/s. The SanDisk 16GB Ultra Flair USB 3.0 Drive offers up to 130MB/s. The Dual Drive is faster in this metric. This difference means you might wait slightly less time for transfers on the Dual Drive. Both drives are fast compared to older USB 2.0 standards, but the 32GB model has the edge in raw throughput numbers.
Connector type
Connectivity defines what devices you can use these drives with. The SanDisk 32GB Ultra Dual Drive features a dual connector design. It includes a reversible USB Type-C connector and a traditional USB connector. This makes it compatible with newer smartphones, tablets, and laptops that use USB-C ports. The SanDisk 16GB Ultra Flair USB 3.0 Drive has only a standard USB connector. It works with traditional computers but not directly with USB-C devices without an adapter.

Security features

This feature is supported on Windows 7, 8, 10, and Mac OS X v10.9, though software download is required for Mac. The product data for the SanDisk 32GB Ultra Dual Drive does not mention built-in password protection or encryption features. If hardware-level security is a priority for you, the Ultra Flair has a clear advantage here.
Build and design
The physical design affects durability and portability. The SanDisk 16GB Ultra Flair USB 3.0 Drive has a sleek, durable metal casing. It measures 1.67 inches in length, 0.52 inches in width, and 0.26 inches in height. The SanDisk 32GB Ultra Dual Drive has a retractable design. It measures 1.5 inches in length, 0.37 inches in width, and 0.79 inches in height. The Dual Drive protects its connectors by retracting them. The Ultra Flair relies on its metal body for protection. Both designs serve different portability needs.
