This is half the capacity of the first option. If you need to store more photos, videos, or documents, the 64GB drive is the better choice. The 32GB drive is suitable for smaller transfers or as a secondary backup. The difference is clear: one holds twice as much data as the other. Choose based on how much content you plan to save.
Read Speed
The SanDisk 32GB Ultra Dual Drive USB-C offers faster read speeds. It reaches up to 150MB/s. This is useful when moving large files quickly. The SanDisk Ultra 64GB USB 3.0 Flash Drive has read speeds up to 100MB/s. The 50MB/s difference matters for large transfers. If you frequently move high-resolution videos or large archives, the faster drive saves time. For small files like documents, the speed difference is less noticeable. The dual drive wins here for performance. The standard drive is adequate for basic tasks.
