Score: 67/100Rankings

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.

The SanDisk 256 GB Phone Drive for Android provides dual-connector USB-C/USB-A connectivity for Android phones and PCs, offering reliable 100 MB/s reads and automatic backup via the Memory Zone app, but its slower writes and lack of encryption limit its appeal for power users.
