How We Tested
We tested each SSD with real-world file transfers, including large video files, photo libraries, and game installations. We measured sequential read/write speeds, random access performance, and thermal throttling under sustained load.

What to Consider When Buying an External SSD
Speed (USB Generation)
USB 3.2 Gen 1 offers up to 625 MB/s, Gen 2 reaches 1,250 MB/s, and Gen 2x2 delivers 2,500 MB/s. Your computer's ports determine the maximum speed you'll achieve.
Durability
Look for IP ratings if you'll use the drive outdoors. IP65 means dust-tight and protected against water jets. Drop ratings of 2-3 meters provide reasonable accident protection.
Encryption
Hardware encryption (AES 256-bit) protects your data without slowing performance. Password protection is essential for sensitive files, especially when traveling.
