I think anyone running a home server qualifies as an enthusiast, there are more uses for home servers than just plex lol

There are definitely valid reasons to use SSDs in a server/array. One of my proxmox servers runs 4x m.2s in raidz1 so all my vms are super snappy. Depending on what you’re running you can really see benefits, for example:

• Elastic Stack
• Network storage for photo editing
• Lemmy
• Immich

Pretty much anything with a lot of metadata or tons of files will see benefits from running on SSDs, this comes with the caveat that cheap ssds wear quickly and are a pain in the ass but if you need it, you need it
