I posted this deep in another thread but thought it made some sense to add as a new one....
Micro SD cards are harder to handle but you can get UHS II and 512GB versions so technically no performance hurdle. Would you buy a dual card adaptor for your single slot camera if redundancy is important but not critical to warrant 2 R bodies?
The Sony Pro Duo memory stick was/is so expensive that there are adaptors for 2 x micro SD cards in one pro duo card. These are quite old now and only used as sequential/additional memory ie not mirrored/redundant
Pro duo dimensions are slightly physically smaller than a SD card so in theory a SD adaptor could hold 2 x Micro SD cards giving us the infamous dual SD card redundancy. SD card 32x24x2.1mm vs Pro duo 31x20x1.6mm vs Micro SD 15x11x1mm
There are a couple of threads discussing the option below. Summary is:
- Possible to do technically.
- Additional points of failure but would solve the failed card scenario.
- Could increase the latency.
- Could be much more complex/power etc if a RAID server/buffer is the solution vs a FIFO solution.
Nothing on the market at this time but I imagine that there would be some pent up market demand for such a product and probably more than a pro duo card market
In the bad old film days with underwater photography, if you wanted >36 shots you needed 2 bodies + housings (strobes) for additional storage or redundancy against flooding!
