If you need a good replacement NAS for Drobo then DS2419+ from Synology might be a good fit. You can also mix drives with different capacities. Also, you can upgrade them without a need to reformat the system.But unfortunately, you can not resize a volume without formatting it.Qnap does allow you to resize volumes but it lacks the option of mixing different size drives in the same volume. Model ts-1685 would be the biggest tower-style NAS they offer. But you can upgrade drives without resetting the entire system. But the drive mixing option might be quite a disadvantage.I hope this helps.
