New M1, Disk Utility Question

[vtyler98]

I purchased a used MacBook Air m1 from BestBuy and I’m completely new to Big Sur. Everything is setup but I noticed before downloading anything the overall storage space seems a bit odd. System preferences shows 251gb of flash storage with 15gb allocated for “system” and then 17gb of “other.” In disk utility it looks odd, like a partition is setup perhaps? Is this how Big Sur formats things and what is the .com.Apple os update below that? A picture is attached for reference.

That's normal

Your "Untitled" is your Big Sur volume which is not mounted.
Your "com.apple.........." is a system snapshot which is what your system boots from.
Your "Untitled - Data" is your user and personal stuff.
As I understand it.

Ok great, thanks for the help! Since it was used and looked a bit strange I wanted to be sure everything was okay. Loving it so far, this battery life is amazing!

"com.apple.........." stuff is new to the Big Sur. Big sur no longer boots from the file system directly, instead it creates a snapshot and boot from that snapshot. With each system update, a new system snapshot is created, and the system boots to that new snapshot instead.

Normal for used, whoever did the erase didn't take the time to name it back - easy fix - rename to "Macintosh HD" as it comes from factory.
