Okay, make it three branches:
* The cheapest bare minimum (sans "apps")
* The bells and whistles (includes self-built "super"micros)
<long price gap>
* The Real Enterprise
I'm not really sure where you're going with this or what you're trying to get at. Or why "super"micros is typed like that. The "cheapest bare minimum" generally have apps. Those features generally continue on up most of the consumer oriented product stack. You can't really divide it into branches. It's all about what each individual users needs are.
On the custom built side, there's a mix. Some people like
aigomorla run theirs as a multipurpose box. Others (like myself) still run their storage box as a straight storage box and leave the other tasks up to other systems (either physical or virtual). Many of these custom builds exceed the entry level business units in every regards save for having a warranty. Cost wise, they're easily as expensive as the lower end business units.
On the "enterprise" side, you don't see apps, they're just straight storage units. I use "enterprise" in quotes because just being business oriented does not make it enterprise. Many small businesses are perfectly happy with the midrange Synology/QNAP units. On the true enterprise side, $100k isn't even a drop in the bucket. I want to say our last batch of drives alone was $250k.
