SanDisk Phone Drive 128GB
Score: 63/100Rankings
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.
