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

[DannyDrive]

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.

I don't have one of these boards on-hand to check the contents of this, but I imagine it replaces one of the two SD cards that MCU1 boards have. If this MCU1.5 board doesn't have one, that confirms it. Probably maps, if I had to guess. Not written to very often, shouldn't be a huge failure risk.
