MacBook Storage Issue
I am new to using MacBook, was always fond of MacS. Now I bought MacBook Pro 2020 and am confused of the SSD space. If I go to disk utility, there I can see 2 SSDs each of 256GB.
Is this something I am not understanding correctly and the disk space is actually just 256GB or there are actually 2 SSDs installed as it shows 2 separate disks of 256GB each with different spaces used.
The shop I bought from said it has 256GB SSD.
Please explain me this, do I have 256GB or 512GB space, if 512GB how can I use 2nd SSD?
Images attached.
TIA.
MacBook Pro 13″, macOS 12.1
