They also asked people to review the exhaust fan to an intake fan raising the hd temps from 3 - 5 degrees and defeating the purpose of the air filter on the front.
did you mean reverse? thats simple enough to just place the filter on the back.

but other than the firmware upgrade to 2100rpm, what would be a drawback of this unit? its only 119 more than the drobo and has TONS more features with it!
