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 Amazon Basics Dual Port 512 GB USB flash drive combines a rugged metal case with fast read performance and dual USB-A/-C connectivity. It excels in capacity and durability but lacks disclosed write speeds and Lightning compatibility.
