More and more underwater photographers are swapping laptops for iPad Pros when it comes to sorting and editing on the road. The weight savings are significant, but the backup workflow changes completely.
The iPad Pro (M2 and later) supports external SSDs via USB-C at speeds up to 10 Gbps over USB 3.2. In practice, transferring a 128 GB SD card of RAW files takes about 4 minutes through a USB-C hub to the SSD. Lightroom for iPad reads files directly from the external drive without importing them into internal storage.
Choosing an SSD for an iPad workflow comes down to three points. The form factor should be compact (NVMe stick SSDs like the Samsung T9 or Crucial X10 Pro fit easily in a waterproof pouch). The connector should be native USB-C (no adapters, no USB-A with cable). The IP rating should be at least IP65 to withstand boat conditions.
A common trap: some SSDs advertise impressive theoretical speeds (2,000 MB/s) but throttle after 30 seconds of continuous transfer due to overheating. For full card transfers after each dive, check sustained speed benchmarks, not just peak numbers.
Look for an SSD with IP65 or higher certification to withstand moisture and sand. Models like the SanDisk PRO-G40 (IP68), LaCie Rugged SSD (IP67), and ADATA SD810 (IP68) are best suited for dive travel. Our comparator's diver score ranks each model by its relevance for this use case.
It depends on your camera, RAW format, and video volume. A photographer with a Canon R5 shooting C-RAW at 150 photos per dive with 4 dives per day will use about 13 GB of photos daily. Add video and a 1.5x safety factor. Our built-in calculator does this math automatically.
IP65 protects against water jets and dust, sufficient for splashes on deck. IP67 withstands temporary immersion (1m for 30 min), ideal if the drive might fall into a puddle or get heavily splashed. IP68 offers extended submersion and represents maximum protection.
For most photographers, a USB 3.2 Gen 2 SSD (1000 MB/s) is more than enough. Thunderbolt (2700+ MB/s) is mainly useful for videographers working in ProRes or RAW video, or photographers transferring hundreds of GB of RAW files after each day. The speed gain only justifies the cost for pro video workflows.
The 3-2-1 rule recommends 3 copies of data, on 2 different media, with 1 offsite. In practice, two portable SSDs let you maintain two copies during the trip. Keep them in different bags in case of lost luggage. Our calculator accounts for backup copies in its estimation.
