Lack of a List-Post header got me again...sorry for the dup Mathias.

Or md/RAID --linear. Given the list you're posting to I'm surprised you
forgot this option.
But running without redundancy of any kind will cause more trouble than
you currently have.
Last words of advice:
In the future, spend a little more per drive and get units that will
live longer. Also, mounting a 120mm fan in the bottom of that Antec
cube chassis blowing "up" on the drives simply circulates the hot air
already inside the chassis. It does not increase CFM of cool air intake
nor exhaust of hot air. So T_case is pretty much the same as before you
put the 2nd 120mm fan in there. And T_case is the temp that determines
drive life.
"silent chassis" and RAID are mutually exclusive. You'll rarely, if
ever, properly cool multiple HDDs, of any persuasion, in a "silent"
chassis. To make it silent the fans must turn at very low RPM, thus
yielding very low CFM, thus yielding high device temps.
