This article covers CalDigit Tuff Nano Plus Rugged IP67 SSD (2TB) USB-C 3.2 Gen 2.
Overview
The CalDigit Tuff Nano Plus is a rugged portable SSD that packs an IP67 rating into a pocket-sized chassis. With 2TB of capacity and a USB 3.2 Gen 2 (10Gbps) interface, it delivers sequential read speeds up to 1055MB/s. It is compatible with Thunderbolt 4, Thunderbolt 3, USB-C, and USB-A through the included adapter. This drive is designed for professionals who need reliable storage in harsh environments — whether that's on a film set, a construction site, or in the field. Its IP67 certification means it can survive immersion in 1 meter of water for 30 minutes, plus it withstands drops from 1.2 meters.
Connectivity & Compatibility
The Tuff Nano Plus features one USB-C port supporting USB 3.2 Gen 2 (10Gbps). It comes with a USB-C cable and a USB-A adapter, so it works with modern laptops (MacBook, ultrabooks) and older PCs alike. It is bus-powered, requiring no external power supply. For macOS, the drive is pre-formatted as exFAT and works out of the box. Windows users will need to reformat to NTFS or another filesystem. Note that it does not support Thunderbolt speeds — it is limited to 10Gbps.
Product Info
Released around 2021, the 2TB model typically retails for around ¥42,900. It carries a 3-year warranty. The package includes a USB-C cable, a USB-A adapter, and a protective carrying case. It can be purchased from or directly from CalDigit. This product sits in the high-end tier of portable SSDs, prioritizing ruggedness over raw speed. While more expensive than standard external SSDs, its IP67 rating and drop resistance make it a niche choice for extreme conditions.
Best Use Cases
Photographers and videographers on location: When shooting outdoors in rain, dust, or sand, this drive provides peace of mind. The fast 10Gbps interface works well for offloading footage between takes. However, heavy continuous writes may limit longevity due to moderate TBW (unknown). Frequent travelers: Its compact size and durable construction make it ideal for tossing into a bag without worrying about damage. The bus-powered design eliminates the need for a separate power brick. That said, for daily desktop backup, a larger, cheaper HDD or internal SSD might be more cost-effective. * Field engineers and surveyors: Working in construction, mining, or outdoor research, the IP67 rating ensures the drive survives spills, rain, and dust. The included carrying case adds extra protection. If you only work indoors, consider a faster Thunderbolt 4 external SSD instead.
