Score: 89/100
ADATA UE800 2TB
Score: 88/100Rankings
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 ADATA UE800 is a high-capacity (up to 2 TB, currently 1 TB) USB-C flash drive delivering near-maximum USB-C 3.2 Gen 2 speeds in a compact brushed-aluminum body. It excels in performance and portability but lacks ruggedness and built-in security features.

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 reviewers such as TechRadar gave the UE800 an Editor's Choice, praising its near-maximum USB-C 3.2 Gen 2 speeds, capless slider, and five-year warranty while noting the lack of an IP rating and built-in security.
Everyday users consistently praise the UE800 for its blazing fast transfers, compact capless design, and reliable cross-platform compatibility, with occasional concerns about the absence of encryption and warmth during extended use.
“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.”
