SanDisk Phone Drive 256GB
Score: 65/100Rankings
The Lexar JumpDrive D400 128 GB offers a metal swivel design, dual USB-C/USB-A connectivity and built-in 256-bit AES encryption, making it a secure and versatile portable storage option. Real-world performance is solid for reads, but write speeds lag and occasional USB-2.0 operation can be a drawback.
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.
