Just looking at generic reliability is probably not the way to look at things.
Need to look at what YOUR environment is and see which drive has the best track record for that environment?
How much read/write per day/hour, # of drives used/heat concerns, what kind of raid, etc?
Drive track record: my knowledge is pretty sketchy on all of them, hence asking for advice. amazon has hundreds of negative reviews on wd red and red pros, but those are for the 3-4TB versions and none of them are recent (within last three months).
Other than that, looking at reviews from other sites that take in hard drive samples sent by companies which proves "best foot forward" logic rather than generic performance and reliability doesn't assure me much.
# of drives: 2 SSDs, 2 hard drives.
mounting solutions: basically a suspension and anti-vibration specialized gear. I'll let you know when the case is done being built.
Read and writes to the storage drives? I don't know, I tend to be a bit of a power user even on my three year old laptop and it keeps up with most of what i do. it occasionally derps and dumps but what machine hasn't?
Hours per day; less than 8: most of which it will probably be at idle/standby/light duty. I have another drive similar to wd black for all my games and content creation.
days per week; probably every day.
The case will have a near ridiculous amount of airflow (one man's opinion), much of it will be focused on the drives.
