Techkey USB Flash Drive 128GB
Score: 79/100Rankings

The Techkey 128 GB MFi-certified flash drive offers versatile three-in-one connectivity and a rugged metal build, delivering fast USB 3.0 speeds. Its main drawbacks are the mandatory iOS app and the lack of detailed size/weight specs. Ideal for travelers and iOS users who need a durable, cross-platform backup solution.

The SanDisk Cruzer Blade 8 GB USB-2.0 flash drive features a retractable connector and SecureAccess encryption in a tiny, lightweight package. Its slow write speeds, fragile plastic connector, and limited 8 GB capacity make it unsuitable for demanding tasks. It fits casual users with basic storage needs on older computers.

Professional reviewers describe the Cruzer Blade as a fairly average performer that meets the needs of most everyday users but falls short for enthusiasts due to its lackluster write speeds, fragile connector, and missing status LED. They acknowledge its good read speeds and convenient retractable design, yet recommend faster USB-3.0 alternatives for demanding workloads.
Everyday consumers appreciate the drive's tiny, cap-less design, plug-and-play ease, and reliable storage for documents, photos, and a few movies, often calling it perfect for basic work files. However, many express frustration over the very slow write speeds and occasional connector flexing, especially when urgent large-file transfers are needed.

“"perfect" for work files”

“"fairly average performer"”

“writes "disappointing" (2.8-3.3 MB/s)”




Professional reviewers highlight the drive's very fast USB 3.0 performance and the convenience of having Lightning, USB-C and USB 3.0 ports in a single, rugged package, while noting that the mandatory BLANBOK+ app on iOS adds a setup step and that independent testing is limited.
Everyday users praise the drive for quick, one-click backups and seamless cross-platform file transfers, especially while traveling, and they value the durable metal build; no major complaints are repeatedly mentioned beyond the required app for iOS.
