Garmese USB-C SSD 256GB
Score: 81/100Rankings
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 GARMESE 256 GB dual-connector flash drive offers fast burst performance and a rugged metal case, making it suitable for creators and travelers. However, its sustained speeds fall short of the advertised rates and it runs warm under heavy load.

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.
Professional testers acknowledge the GARMESE drive's impressive burst speeds and convenient dual-connector layout, but they criticize its over-stated sustained performance and the lack of a sizable cache, which causes noticeable speed throttling on large transfers.
Everyday users praise the drive's quick initial transfers, sturdy metal housing and the ease of swapping between USB-A and USB-C devices, but many complain about speed drops on big files, warmth during long sessions, and occasional Android compatibility hiccups.
“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.”
