SanDisk 64GB Ultra vs Dual Drive Go
Storage Capacity
The SanDisk Ultra 64GB USB 3.0 Flash Drive offers twice the storage of the SanDisk 32GB Dual Drive Go. You get 64GB of space on the Ultra model, which is useful for larger files or more photos. The Dual Drive Go provides 32GB, which is sufficient for smaller tasks but fills up faster. If you need to store more data without switching drives, the 64GB option is the better choice. The difference is clear and directly impacts how much you can save at once.
Read Speed
Speed matters when you move large files between devices. The SanDisk 32GB Dual Drive Go lists a read speed of up to 150MB/s. This is faster than the SanDisk Ultra 64GB USB 3.0 Flash Drive, which tops out at 100MB/s. The Dual Drive Go transfers data more quickly, saving you time during backups or media transfers. The Ultra drive is still fast for standard USB 3.0 use, but the Dual Drive Go has the performance edge here.
Connector Type
Connectivity defines how you use each drive. The SanDisk Dual Drive Go features a dual connector design with both USB Type-C and traditional USB Type-A ports. This lets you plug it directly into modern smartphones, tablets, and Macs without an adapter. The SanDisk Ultra 64GB uses only a standard USB Type-A connector. You need a computer or a USB-C to Type-A adapter to use it with newer mobile devices. The dual connector offers more versatility for mobile users.
USB Version
The underlying interface version affects compatibility and potential speed. The SanDisk Ultra 64GB USB 3.0 Flash Drive supports USB 3.0 and USB 2.0 standards. The SanDisk 32GB Dual Drive Go supports USB 3.1 Gen 1, which is backward compatible with USB 3.0 and 2.0. While both work with older ports, the Dual Drive Go uses a newer standard that aligns with its higher read speed claims. This makes it slightly more future-proof for newer host devices.
Physical Dimensions
Size affects portability and where you can store the drive. The SanDisk Ultra 64GB is compact, measuring 0.87 inches in width and 0.42 inches in length. It is designed to slide into a pocket or keychain easily. The SanDisk Dual Drive Go is significantly larger, measuring 4.09 inches in width and 5.94 inches in length due to its dual connectors. The Ultra drive is much more pocket-friendly, while the Dual Drive Go is better suited for desk use or carrying in a bag.
