Score: 84/100Rankings
The Kingston IronKey Locker+ 50 32 GB delivers enterprise-grade AES-256 hardware encryption, metal durability, and fast 145 MB/s read and 115 MB/s write speeds. Its limited capacity and higher price point may deter casual users. Targeted at security-focused professionals and organizations.
The SanDisk Ultra Fit 512 GB USB-A flash drive offers an ultra-compact low-profile design with blazing up-to-400 MB/s read speeds and a massive 512 GB capacity. Its lack of a protective cap, unspecified write performance, and USB-A-only interface limit its suitability for heavy write tasks or newer devices. Ideal for users needing permanent, low-profile storage on laptops or TVs.

The Kingston IronKey Locker+ 50 32GB is a compact, enterprise-grade encrypted USB flash drive featuring FIPS-certified AES-256-bit XTS hardware encryption and a metal silver casing with a key loop. It offers plug-and-play use on Windows and macOS, USB 3.2 Gen 1 speeds up to 145 MB/s, and optional cloud backup via USBtoCloud.
Everyday users appreciate the drive's quick read response and convenient keyring design, but the overwhelming complaint centers on sluggish write speeds and occasional data integrity problems. Overall sentiment is mixed, with many recommending it only for light, read-heavy use.
Professional reviewers and editors emphasize the Ultra Fit's ultra-compact, plug-and-stay form factor and its impressive 400 MB/s sequential read performance, positioning it as a high-speed, low-profile storage solution that outpaces USB 2.0 drives by a large margin, though they caution about the lack of a protective cover and the USB-A only interface.
Everyday consumers consistently highlight the drive's fast read speeds and massive 512 GB capacity as major strengths, while repeatedly mentioning the missing protective cap and occasional warmth during extended use as drawbacks.
