"Normal operation: 20.9dB (negligible) to 24.2 dB" with the fine print "Acoustics tests performed 1m from the front of Drobo with four 1TB Western Digital GreenPowerâ„¢ drives during a file copy to Drobo. Drobo has a smart, five-speed fan governed by multiple internal temperature sensors that will normally be off or operate on its lowest setting. The fan is programmed to minimize noise, but never at the expense of disk integrity. The fan can switch to higher speeds if necessary in in hot operating environments or during strenuous usage to protect drives from overheating up to 38.1dB."
As for your question, Jorlem, It looks like you can toss new drives there at any point, but they have to be formatted before going in. So you'd want to put your first drive in there before starting to use it. And also, it looks like if you have one disk in there, you don't want to slot in a much smaller disk in as your second. Check out the Drobo Capacity Calculator. "Available for data" is how much space you'd actually have.
