Some consumer drives aren't well suited to continuous use - they're designed and rated for only a few hours a day. Heat and vibration tolerances are lower. I wore out some WD Greens that way - they were throwing errors by 60k hours.
NAS drives are the opposite, they're designed to run 24/7. In the same way, enterprise drives are designed for better vibration tolerance to be crammed in a chassis with many other spinning disks.
Basically they'll work, but longevity is an issue, which is particularly relevant to us hoarders. I use WD Reds in my NAS and enterprise/SAS drives in my servers now. Seems to be a good combination.
