OS X :: Looking For A Quieter RAID 1 Enclosure?

I have a 1TB x 2 setup in a Guardian Maximus enclosure, which i like, but it is noisy. Per OWC support, the noise levels i have are pretty normal.

The noise is not server room noisy, I will admit that

However, this setup is connected to my Mac Mini, always on and serving up my iTunes content to 2 apple TVs. Previously, I had been using 500gb and 750gb external drives, no RAID. Both previous drives (Seagate free agents) ran perfectly quiet enough.

The big thing is, in my apartment the setup is on my TV center, and that is close to our bed. the Seagate drives were inaudible, the only thing noticed was the orange light if i didnt shut the light off in the config. But you couldn't hear the drive noise otherwise.Not so with the Maximus. Its a constant hum, and the wife has now commented about it. Which means i need to either

a-quiet the maximus

or

b-replace it with something quieter.

so I wanted to see if anyone had experience with the maximus, alongside something like the WD Mirrored options, the Lacie RAID1 options or anything else. $250 is about my budget for this.but now i am wondering if i shouldn't just get a 1tb solo drive, use that for the main iTunes drive and then fire up the RAID1 enclosure once a week and back up the media (my main reason for the RAID was getting concerned about losing all my ripped content).
