Does the flash memory in an iphone have a lifetime that would be reached if one continuously records video?

I am looking at dash cam option and plan to get the new iphone whenever and have my 4s be a backup phone while playing duty as a dashcam in the meantime.

Or is the flash high enough quality that it would take years upon years to degrade.

Thanks

Have the phones been out long enough using flash techology to know how long they'll last? I'd be curious to know too...

With newer tech you shouldn't have to worry about anything. Flash drives now have "wear leveling" so things are evenly written and read. The memory in an iPhone is higher quality then that so you'll likely experience other issues before memory failure. And even those "other issues" won't likely happen till after your feel like getting a new phone anyway.

Do we know if the memory is SLC, MLC, or TLC?

How do you know how soon the OP intends to replace the iPhone being used as a dashcam?
I assumed it would be sometime over the next 10 years. I don't know really, could be wrong. Don't keep me in the dark, what the answer?

4 uses Samsung MLC (previous iPhones too)
4S uses Toshiba MLC
5 uses Hynix MLC

Or so I've read, I haven't tried to dissect its part and serial numbers personally.

Edit: I've been looking for the link to link I read the 5 uses MLC but I can't find it. I believe it was determined because of its size it was believed to still be MLC since comparing to know MLC NAND is so easy from previous generations. But no rock solid proof either way.
