Score: 81/100Rankings

The Crucial X9 Pro for Mac 1TB delivers Mac-optimized performance of up to 1050 MB/s in a tiny, IP55-rated aluminum case with strong 256-bit encryption. Its 10 Gbps USB 3.2 Gen 2 interface caps peak throughput below newer 20 Gbps models, and the IP rating is modest compared with IP65 rivals. Ideal for Mac-centric creators and travelers who value portability and native compatibility.

WD's My Passport SSD 500 GB provides fast USB-C performance with built-in 256-bit AES encryption and a rugged 1.98 m drop rating, making it a secure, travel-ready option. Its limited cache and modest random I/O performance, plus lack of water resistance, may deter power users. Ideal for mobile professionals who prioritize security and durability over extreme speed.
