Exactly that
I bought it a while ago for another PC which kept failing, but didn't continue to use the software afterwards. Thankfully this time round I'm configuring Drivepool from the get go.
I like the fact if worst case scenario the motherboard/controller fails you can pull the disks into another PC or external disk housing and you're up & running again. The only other ultra worst case scenario is CoveCube go under and the licence fails, but the fact they have a cloud subscription service and money flow I can't see that happening.
I got a good bundle when I bought it which included all 3 products that they develop, so I might experiment with the cloud storage portion. Could be useful for things like phone & laptop backups when away.
The only other 3rd party Drive Pool software I'm aware of is M-Division, wondered if you'd tried it?
The inbuilt Microsoft one with Server Essentials is awful.
