Solution
As mentioned by @AbominableSlinky@lemmy.world, information can be found here.
TL;DR: mdadm can be configured to notify you, via email, if you are having any hard drive issues.
From the shared link, see “Monitoring RAID Arrays”:
You can run mdadm as a daemon by using the follow-monitor mode. If needed, that will make mdadm send email alerts to the system administrator when arrays encounter errors or fail.

I would like to set up RAID 1 for a server of mine, but I am wondering if its possible for some form of notification system for that can be set up.
Perhaps a push notification to my desktop, or a prompt when I log in via SSH or some other method. I just don’t want to have to run diagnostic commands constantly to check drive health.
I’d also suggest looking at ZFS. Works great on Linux and it’s super powerful.
Not only that, but replacing a failed drive is easy. The resilvering process is dead simple.
ZFS also directly addresses this issue in that a scrub can be setup in cron, which will detect any data issues and send email. One could do that with smartctl too, but that can be too late, where a ZFS scrub is more likely to let you know of issues before data loss.
