Hello everyone, I recently upgraded to macOS Catalina after its released and publicly available to everyone. and realised that I now have two drives as follow:
I am not sure how this happened. How to rectify this make them look like a single drive.

No.
Everything is as it should be in the macOS Catalina.
When you upgrade to Catalina, your current macOS system volume is renamed, e.g. to "Macintosh HD - Data", its role is set to Data, and then a new volume is added to your startup disk's APFS container with the System
role and simultaneously grouped with the Data volume. The two volumes
within that group share special bonds and receive special treatment from
the Finder and from each volume's filesystem. From the user
perspective, these two volumes are treated as a single

why is it displaying 2 disk drives, can't it show only one?
I've found this link saying this happened because its in beta : https://discussions.apple.com/thread/250482395.
but I upgraded to Catalina once it is available. still having the issue mentioned in the link.

That's not what the link says. Catalina shows two drives, beta or not
but I upgraded to Catalina once it is available. still having the issue mentioned in the link.
It's not an issue. It's normal
is there anyway to maintain it as a single drive?
No. For security reasons there are two volumes in Catalina. One contains protected system files, the other users files.
There is nothing to rectify. It is normal for Catalina.
Come on, Surely having 2 disk drives is a bit confusing right to know which is for what?. Why the need for second drive for same OS?
Thanks , after reading this link : https://bombich.com/kb/ccc5/working-apfs-volume-groups you have provided it's I can understand. many thanks for the help.
I've recently upgraded to macOS Catalina and seeing 2 drives in disk utility
