Score: 67/100Rankings
The SanDisk Ultra Fit 512 GB USB 3.2 Gen 1 flash drive packs massive storage into an ultra-compact, low-profile design. It delivers excellent read performance and encryption, but its write speeds are notably slow and the plastic case offers limited ruggedness.
The Amazon Basics Dual Port 512 GB USB flash drive combines a rugged metal case with fast read performance and dual USB-A/-C connectivity. It excels in capacity and durability but lacks disclosed write speeds and Lightning compatibility.

Professional reviewers commend the Ultra Fit for its minuscule size and impressive read performance, positioning it as an ideal solution for devices with limited space, while warning that the write speed is a major bottleneck.
Everyday users love the drive's ability to stay hidden in laptops, consoles, and car stereos while providing ample storage and fast media playback. The dominant complaint centers on painfully slow write speeds and the difficulty of removing the drive once fully inserted.
“Perfect for my PS5 - fits behind the panel and stores game saves and screenshots.”
“I leave it in my laptop all the time - barely sticks out.”
“Fast enough to play 4K videos directly from the drive.”
Professional reviewers praise the drive's dual-port design, high read speed, and durable metal housing, earning it the Amazon's Choice label and positioning it as a top choice for photographers and videographers needing fast, cross-platform storage.
Everyday users appreciate the fast read performance, solid build, and plug-and-play ease, but many note that actual write speeds fall short of expectations and that the drive cannot be used directly with Lightning devices.
