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.

The Samsung BAR Plus 128 GB USB flash drive combines a sleek metal body with waterproof and shock-proof protection, offering decent performance for everyday use.

Professional reviewers acknowledge the BAR Plus as a solid mid-range USB flash drive that delivers a noticeable performance jump over Samsung's older BAR 3.0 while maintaining an attractive price per gigabyte. They commend its metal build, compact design, and five-year warranty, but criticize the gap between advertised (400 MB/s) and real-world sequential read speeds (≈283 MB/s) and its modest write speeds, positioning it below premium options like the SanDisk Extreme Pro.
Everyday users generally praise the drive's durability, attractive design, and ample 128GB capacity, noting reliable plug-and-play operation across devices. Recurring complaints focus on occasional disconnections, heat buildup that can lead to failure, and the lack of a dust cap, with a few reports of corrupted files during transfers.
“USB 3.0 speed is very fast on computers.”
“NWT, ideal for travel.”
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.
