The Samsung T7 (left) and SanDisk Extreme V2 (right) are both durable, but the latter ups the ante by having an IP55 rating and a more rugged build.

When it comes to looks, the Samsung T7 portable SSD is pretty basic. It has a full metal enclosure with the “SAMSUNG” branding on the front, but not much else. Located at the side is the USB-C port and a single LED light. It’s available in three colors, it measures 3.3 x 2.2 x 0.3 inches, and it weighs 2 ounces.

On the other hand, the SanDisk Extreme V2 has a more unusual design with excellent portability and durability. The silicone coating on the enclosure effectively protects the internals, and the built-in carabiner loop is helpful when travelling. It measures 4 x 2 x 0.3 inches and it weighs 2.22 ounces, so it’s a bit bigger than the Samsung T7, but the difference is not that significant.

Both portable SSDs are durable, but the SanDisk Extreme V2 has the slight advantage here. The Samsung T7 has a full metal enclosure that’s also shock resistant. In contrast, the SanDisk Extreme V2 has a silicone coated plastic case that’s also shock resistant, and it also has an IP55 rating, making it water and dust resistant.
