LaCie Rugged SSD Portable 2TB
8.7/10

The 2TB non-Pro Rugged SSD keeps the iconic orange armor but doubles capacity. A frequent pick for outdoor photographers shooting medium-format RAW, where the IP67 rating matters more than the Pro model's Thunderbolt speeds, and the 950 MB/s USB-C is plenty fast.
