Score: 78/100
Crucial X9 Pro
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.
SanDisk Extreme Portable 1TB SSD combines IP55 protection, shock-proof construction, and NVMe speeds up to 560 MB/s in a compact form factor. Heat during sustained transfers and a higher price are notable trade-offs. Best for on-the-go professionals needing rugged, reliable storage.
