So I have a SnapServer 4100 sitting in my basement and I can't for the life of me remember what the maximum supported capacity for an individual disk is. I know it's a bit older in terms of hardware, but I thought I might try my luck. I tried googling it and all I could find were results for the factory configurations, not the maximum disk size.
Here's a datasheet for more info: http://www.backupworks.com/PDF/Datasheet_4100.pdf
