Creating a bootable drive for your Mac certainly seems to be a wise decision to make. Even though MacOS recovery partition can take care of all your recovery requirements in times of need, it’s still worthwhile to have a bootable installer.
Why Do You Need to Create A Bootable Drive For Your Mac?
The Mac installer gets deleted as soon as you download it and use it by installing the Mac operating system. Once the installer gets deleted, it means that you can no longer use it to install the MacOS on another Mac device. You will have to again download the installer on the latter Mac to install the MacOS. This can take a lot of time and become inefficient if you have multiple Macs.
Clean installs can be performed by installers which are very helpful in overwriting your start-up drive. You can also use this function for other troubleshooting issues as well.

What Do You Need Before Creating Your Bootable Drive?
Before you begin the process, you will need the following:
USB Stick / External Hard Drive: If you are planning to use a USB for downloading the bootable version of the installer, make sure that it is 8GB in size or larger than that. In the case of Sierra, 12GB is recommended as the minimum requirement. Ideally, 32GB to 64GB is a good size to have as it is not only cost-effective but also gives a better performance. In the case of an external drive, you can use any spare one that you are not going to use for any other work.
Download MacOS High Sierra Installer: It is important to note that once you have downloaded the installer, it will begin with the installation process on its own. You can close the installer just like you quit any Mac app. In the case of the macOS version being older than the current one, you can click on ‘ok’ once the message flashes that the version is too old to install. You can find the old installer file in your ‘Application Folder’. Don’t forget to take a backup of your Mac to be on a safe side.
