NAS products are equal parts hardware performance and software features. One compliments the other in a balanced product. You need more hardware performance to run more software features at the same time.
Just because a NAS has the ability to run SQL doesn't mean the hardware will let you run SQL at a high rate of speed while a user downloads Bit Torrent, watches YouTube and decompress an NZB file.
The trend over the last few years has been to load NAS products, even higher end enterprise units, with a massive list of consumer features. Infortrend went the other way and doesn't include Bit Torrent, NZB, media player and other consumer-focused functions.
Instead of consumer features, we get a long list of true enterprise features like a ZFS file system, data dedupe, data compression, corrupt data self-healing, snapshot, pool mirror and remote replication. None of these CPU intensive features will slow due to a rogue administrator downloading Dora via the NAS to take home to the kids.
