Score: 95/100
OWC OWCENVPK04
Score: 88/100Rankings

The Crucial X10 Pro 4TB Portable SSD delivers up to 2100/2000 MB/s via USB-C 20 Gbps, IP55 ruggedness and 256-bit AES encryption, but its performance is limited by the need for a Gen 2x2 port and some users report early failures.

The OWC Envoy Pro Elektron 4 TB delivers near-internal SSD speeds in a rugged, IP67-rated aluminum enclosure while remaining lightweight and bus-powered. It's bootable and cross-platform but lacks a protective case and hardware encryption.
