SanDisk Extreme PRO 512GB Dual
Score: 79/100Rankings
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 SanDisk Extreme PRO 512 GB Dual Drive delivers near-advertised sequential speeds, a rugged metal case, and hardware encryption, making it ideal for creators who need fast, secure transfers across USB-C and USB-A devices. Its size, weight, and price keep it from being a pocket-friendly everyday drive.
