MCU1 Motherboard (not daughterboard) 16 GB Sandisk EMMC (iNand) chip experience and replacement? "See pics"

Hi there,

I have found an 16 GB Sandisk EMMC iNand chip on the MCU 1 Mainboard (this is not the daughterboard Micron emmc chip). Pics are below.

I like to open a discussion over here about this EMMC iNand chip. Can everyone share his experience about this chip like...

- what exactly the system ist writing on?
- will the system use only use a part of the 16 GB the total space
- will be files frequently written on this chip?
- anyone tried to replace it with a bigger GB size or even faster write and read speed chip?
- is it replaceable with or without risk?
- is it under worn out risk?
- is this the EMMC which is only on a MCU 1.5

I am pretty sure there will be coming up more question for everyone who is curious about this chip as well.
