Teamgroup C175 1TB
Score: 82/100Rankings

The TEAMGROUP C175 1 TB USB 3.2 Gen 1 flash drive offers massive storage in a compact, stylish package with fast read speeds and a lifetime warranty. Its lack of official write-speed specs, modest write performance, and fragile snap-on cap limit its appeal for power users.

The Transcend JF790 512 GB USB flash drive offers high capacity and a convenient retractable design, making it suitable for everyday storage across many devices. While its speeds are adequate for typical documents and media, they fall short of premium drives, and it lacks encryption.
