It wasn't anywhere near that noisy, as I recall it was more of an annoying
buzzing noise.  Even the 6 JBOD canisters with 18GB 10K drives sitting 4
feet away from where I sit aren't that loud.  In fact they aren't as loud as
the Sparc 5/110 that I was running up until 2-3 months ago in the same rack. 
It did get retired to quiet things down.
