Offcoarse they will ask more just because it's enterprise and yes, you will pay a lot for support. It took years before netapp started SSD support and thats because SSD's were evolving to fast, they offer services that you will get the exaxt same drive as replacement, even if we are talking 8 years later and you can't get them anymore anywhere, they will be on your desk within 8 hours, they couldn't do that because drives on the market and chips were being put EOL in record times. (but that support will cost more then the drives themself)
But that it's just the same HW with a diferent firmware, they may lock features but the HW is quite different. I haven't looked it up but I expect that 960GB flash drive has 100% redundancy flash, meaning in reality its a 1920 GB drive. Consumer drives, perhaps you get 5% or you may get 0%. "Pro drives" may go to 20% It will also have redudant controllers and safety for upgrading the controller firmwares, your consumer drive won't. (if the controllers screws up in a SSD, the data is still there but you can't make any sense of it anymore ending up in total loss of data)
Another issue is that you are just looking at expected life, I have pretty expensive USB thumb drives will hit 300-400 MB/sec without drops on a 200GB file copy but they will be very, very hot after 200GB of data. That isn't an issue because after that copy it will cool down and it's designed to handle a short burst of heat, in fact they are quite thick because the outside is solid metal designed to get that heat out. But start doing that for multiple hours and that thumbdrive will get into big trouble because of heat.
For flash memory you get into trouble when it starts to get full, because it cant move data around, it cant choose anymore where to put it and it will start to keep writing the same cells over and over ending up overloading cells instead of balancing.
A normal SD card only has a basic controller that doesnt care, and for normal use, who ever writes the damn thing full all the time? I even expect the endurance versions to have the same basic controller, it's hard to give it a complex controller at that physical size while it should behave to the host as a stupid controller because it must support SD card readers that never got any complex command structure as SD cards were never designed for this kind of use anyway. It's only after SSD's started to get mainstream they started updating commands support for flash drives but SD cards yet have to get those.
However those endurance cards do use MLC NAND flash that is more expensive and slower but it will last longer. Also it will have some form of error correcting so that it can take an error once and a while without issue. But if you don't have that, well what does the Viofo do when it gets a write error once and a while?
But then you have consumers, they are not intrested, it must be fast and it must be cheap just like their RAM that doesnt have ECC. You will get bitflips but as long as you sometimes reboot the computer and you use it under normal circumstances, perhaps the system will crash because of that once in 10 years. But start pumping that RAM on a 24/24 7/7 system, you will learn to buy ECC server graded RAM the hard way.
