Computer accessory manufacturer CalDigit has released its ‘Tuff nano’ series, a lineup of compact external USB-C SSDs.

As the name alludes to, the ‘Tuff nano’ SSDs feature a protective rubber housing around a metal frame, akin to Lacie’s rugged external drives. This design offers a certified IP67 rating with the ability to be submerged under one meter of water for 30 minus, as well as dust and shock resistance.

Inside, the bus-powered SSDs is a Toshiba M.2 NVMe SSD capable of read and write speeds up to 1055MB/s and 900MB/s, respectively. Data is transferred via USB-C (USB 3.2 Gen 2) and although the drives come pre-formatted for macOS (HFS+), they will also work with ChromeOS, iPadOS, Linux and Windows devices.

The drives measure 7.59cm x 5.44cm x 1.45 cm (2.99in x 2.14in x 0.57in) and weigh just 74g (0.163lbs).

CalDigit’s ‘Tuff nano’ SSDs are currently available in 512GB capacity for $149.95 on CalDigit’s online store. Color options include ‘Charcoal Black,’ ‘Olive Green,’ ‘Royal Blue’ and ‘Tomato Red.’
