I am just going to echo a little of what Matthew McCarter said, as I think we are having a similar experience.
We currently have at least 5 servers just for our scan data(some offsite for synced backups at other offices). 2 of them are HP enterprise class servers with very fast drives and one of those has 10GE connectivity to our workstations, which is awesome for working on data over the server. For archiving, we bought a rack mountable enterprise class Qnap with 64TB(28TB usable) of storage in a Raid 10 in case two disk fail. It was a great box to archive our old projects, and even work from when we had to revisit one. Recently it started to have issues where it would vanish from the network, and then come back again later. Our IT group spent a great deal of time with Qnap support trying to solve the problem, but ultimately they determined there was some sort of massive corruption that was unrecoverable. The funny thing is that all our data is still intact, and all the drives still pass as operational. Since no remedy can be found, we have since purchase two Synology NAS units each with the same storage space as the Qnap to now assume the archival role. The big difference now is that if one NAS fails entirely the other NAS is in high availability mode to take over so we never skip a beat

I don't really have an opinion to which brand is better, but I think
redundancy of the entire system should be strongly considered. Raid redundancy in a single NAS is not enough...at least for us. Oh, one other thing...the two Synology NAS drives will cost less than the Qnap did, so there is also that.
