Other Technical information about usb tethering

I have an iPhone 6s that I use everyday as my main internet modem for my pc through usb tethering. I got unlimited mobile internet and I average about 70gb of data in download everyday.

I need to know the following: is all the data I tether being momentarily written and than immediately deleted from iPhone storage memory?

My worry here is killing its 32gb internal flash NAND. The smaller the storage the lower the write / erase cycles the chip can go though, and 32gb is pretty small and definitely its not designed to go though 70gb of writes each day.

The phone is running ios 12.4.1 and the computer windows 7 in case that matters.

Don’t know for sure but it’s most likely just passing through the RAM without being written to SSD.

Can anyone else share their thoughts on this please?

The iPhone acts like a router in this mode. There probably is minimal additional - compared when you use just as a mobile - data logged to the iPhone, but there is no temporary big chunk intermediate storage of the data on the iPhone.
If this intended as a permanent solution and the iPhone is also used for “iPhone stuff” 😎, I personally would get a cheap mobile hotspot and use that.
