Frequently asked questions about portable SSDs for dive travel
Which portable SSD should I choose for underwater photography and video?
Prioritize a drive certified at least IP65 against dust, sand, and spray. Waterproof IP67 or IP68 models like the SanDisk PRO-G40, LaCie Rugged SSD, and ADATA SD810 survive accidental submersion in rinse tanks or seawater.
What is the practical difference between IP65 and IP67 or IP68 on a boat?
IP65 protects against splashing water and sand on boat decks. IP67 guarantees temporary immersion up to 1 meter depth for 30 minutes, while IP68 offers extended submersion and maximum ingress protection.
Do you really need a Thunderbolt SSD for underwater photography?
For standard RAW photo workflows, USB 3.2 drives delivering 1,000 MB/s are fully sufficient. Thunderbolt speeds exceeding 2,700 MB/s are only necessary for videographers offloading hundreds of gigabytes of ProRes or RAW video daily.
How do you apply the 3-2-1 backup rule while traveling on dive trips?
The 3-2-1 rule advises 3 data copies across 2 media types with 1 offsite. During dive travel, keep your written SD cards unformatted and maintain two duplicate SSD copies stored in separate bags.
Which SSD works best with an iPad Pro for reviewing photos between dives?
USB-C iPad Pros easily power compact bus-powered drives such as the Crucial X9 Pro, Samsung T7 Shield, or SanDisk Extreme V2. You can cull and edit RAW files directly in mobile Lightroom without using tablet storage.
Why do some SSDs overheat and throttle transfer speeds in tropical climates?
In ambient temperatures above 35°C, flash memory chips experience thermal throttling under heavy continuous write loads. Choose drives with aluminum or titanium heatsink casings that dissipate heat effectively.
