For years, early adopters and beta testers would partition their Mac's hard drive in order to test a new or beta version of macOS. Partitioning your hard drive actually creates a separate container on your hard drive that is limited in its abilities.
If your Mac uses APFS, you can actually create a volume right on your current hard drive instead. This allows your hard drive to manipulate your available storage temporarily as you need it. It makes testing new or beta operating systems much easier to do and easier to remove when you're done testing them out.
IMPORTANT: The developer beta of Big Sur is currently experiencing some issues with installing and updating versions including and most importantly, installing Big Sur onto separate volumes.
From Apple's developer support notes for Dev beta 2:
You might be unable to install macOS Big Sur 11 beta onto additional volumes. (63677460, 64445236)
If macOS Big Sur 11 beta is installed into the same APFS container as previous versions of macOS, system software updates can no longer be installed on the previous versions of macOS. (64411484)
If you are installing the developer beta of macOS Big Sur, we highly recommend going with partitioning your hard drive not creating a volume.
Before you start
The most important thing to do before making any changes to your hard drive is to back it up. Seriously. Back it up. Please. Time Machine is the easiest way to back up your data if you don't already have another system in place.
Second, make sure you have enough free disk space to properly run a secondary operating system. Shoot for at least 30GB free, though I recommend closer to 50GB if you have it available.

What's the difference between a disk partition and a volume?
A partition and a volume act in very similar ways, but creating a volume allows for flexibility of storage needs while creating a partition separates storage with a specific amount and does not adjust for each drive's needs.
What is a partition?
Partitioning your Mac is basically splitting your hard drive into separate, usable systems. It makes it possible to run two separate operating systems on one device, like Windows and macOS, or two versions of macOS (like Catalina and Big Sur).
Note: If you want to run Windows on your Mac, Apple's Boot Camp assistant will automatically make a partition for you. Here's how to install Windows.
It is important to note that partitioning your hard drive also splits up your available hard drive space. Each partition will take up a portion of your usable storage. So, if you are running low on storage capacity on your hard drive, we don't recommend partitioning.
If you are running a Mac using HFS+ file system (prior to macOS Catalina) you must partition your hard drive. If your Mac uses APFS, Apple recommends creating a volume instead.
What is an APFS volume?
An APFS volume creates a similar container to be used the same way as a partition, but it mounts it within your main hard drive. This allows the volume the flexibility to grow or shrink in storage size as needed. You don't have to worry about running out of temporary space while installing macOS, for example, because it will grab the necessary space from your main drive and then put it back when it's done. You can manually select size limiters for a volume if you're worried about one drive overtaking another's space.
If your Mac uses APFS, Apple recommends creating a volume instead of a partition.
How to add an APFS volume on Mac
You can test the beta of Big Sur on your Mac without having to change anything on your daily driver by creating a volume that acts as a separate drive so you can install a completely different operating system. This allows you to switch between OSes using the Startup Disk option.

You have the option of selecting a specific size that you want the volume to be, which will guarantee this volume will always have the reserve size you want. However, APFS volumes are designed to allocate disk space as needed. If you're worried about running out of disk space on either your main drive or the new volume, you can select a minimum/maximum volume size. After completing Step 7 above:
- Click Size Options.
- Enter a Reserve size to ensure that the new volume will always have a minimum amount of space.
Enter a Quota size to ensure your main drive never runs out of space.
