Streamer Operating System Storage: SSD vs EEPROM?

@lalitk So I thought I understood what Aurender meant by buffer vs cache until I did some googling and frankly I'm not sure it isn't just marketing claiming that their [temporary storage location] is implemented better.   Buffer and cache are both terms to describe temporary storage.  Cache is more often used to describe the storate of data that will be used multiple times--not applicable to streaming music.  

So I take what they are saying is "ours are better than the others" and we expect ever vendor to say that.

I'm not saying aurender doesn't make great equipment.  Glad you guys like yours and probbly would have owned one if they played with roon.  

But I don't think this claim by aurender answers the OP question of where the operating system is.

They use apron not eprom

Thank you everyone for contributing. I guess the picture is a bit clearer in my mind. So basically the OS is stored in flash memory or an SSD (SSD is composed of flash memory chips). I was looking at the Innuos web page for the Pulse Mini, and found this:
-Industrial-Grade SSD module specifically for the Operating System with power-loss protection
-Low-Density Parity Check ECC engine and Global Wear-Levelling technologies

I am assuming other manufacturers like Aurender, Lumin, etc. do the same.

In case of Aurender, the operating system is stored and loaded from an SSD, which is also used for the system cache.
