So by your seat belt experience, wouldn’t it be foolish of me to state the equivalent, example?
I’ve never needed a seat belt, nor have any of my friends. Most of the people I see using seat belts, don’t wear them properly. Therefore, I see this as a feature pushed by scientists and the government and not actually needed by professional drivers.
To someone like yourself, I would hope a statement like that would be very foolish and illogical, because it is. You don’t need any data if you already know that seat belts are effective for their designed purpose and car accidents happen.
We all know the purpose(s) of dual card slots and they’re effective at mitigating and preventing the problems they’re designed to protect against, when used properly.
Do you really need any data on how often a card fails? You actually can see that data, as you already know by your claim of a shelf life in your hard drives. Digital media and the disks they’re stored on have a shelf life and failure rates you can research on your own.
What’s the difference between in camera vs in computer? The risks are the same. Why have redundancy and backup only after the data leaves the camera?
I used the Raid 1 & 10 example as that’s pretty much what is happening in dual card slots if you’re using it for redundancy. We use Raid 1 for our working drives, backed up externally and swapped with off location storage. We mirror this practice with our CF and SD cards. Mirror, swap, different location, etc. to prevent loss, damage, theft, etc.
Reputation, cost, legal, etc are among MANY reasons to have a good digital workflow, as you perceive to be doing yourself. I would disagree with your workflow as it’s not right for us and we have a higher standard of mitigation.
No, we don't know that! We have half assed anecdotes and messages pushed by manufacturers and influencers. On the other hand seat belt laws were implemented because of hard data gained in a systematic and authenticated way over many years across relevant numbers.
All I am saying is I believe the necessity of dual card slots and the way they are pushed as being a requirement for a camera to be considered 'pro' is vastly overstated, and my varied and long term single point anecdotal experience backs that up.
Seatbelts and long term digital storage are poor references for comparisons. Digital medium format is the preserve of the very richest amateurs and pros with the highest paying clients, yet dual cards are not considered a 'must have' feature. There are far too many anomalies where dual card slots are just not relevant to back up the meme that stills pro cameras must have them to be taken seriously.
