Your two criteria limit you from your goal. Is this going to be a server in a dedicated, hardened server room or something in a corner of an office ?
Drivers intended for server farms are not equipped with features that protect drives in a consumer environment. The major factor here is head parking which "parks" drive arms and heads when not in active use. In an office, subject to routine vibrations and "desk bumps", this feature is essential. When used for server farm type loads, this feature can accelerate drive failure as the head parking feature is rated for 250k to 500k cycles.
In a server farm, this could take place in a matter of months. This is what Backlbaze does, choosing consumer drives for a server farm is an extremely bad idea ... 1) their drives are held in place with rubber bands, 2) the head parking feature will kill these drives in a matter of months. However, the the typical small / medium size office type environment, this is not an issue.
Large 4 TB drive sizes have a very high failure rate compared to 2 TB drives. Here's some real world test data for drives thta failed within 6 and 12 months of use:

Again, I am assuming you are building a small office / home server with < 20 or so users in which case I would use consumer drives or even an NAS.
How much usage (Read + Writes) do you anticipate ? Light duty drives would handle about 800 GB per day; enterprise drives about 3 times that.
How many drives ?
