Cameta Camera performed the following testing on a Sony Tough Card and it passed all of them without an issue until they ran over it with a car and cracked the card.
Rinse cycle test
Freezer test
Heat test
Dirt test
Stress test
I wonder if others will start making generic cards with a single sealed design to increase reliability like Sony’s Tough card. The Sony Tough cards look to be the best cards on the market at this time if you care about reliability, but they are pricy and a good generic tough card could do well and help to drive down Sony’s prices.
