Sorry to bring up this old thread but I was searching around as I've just decided to return my iMac with fusion drive for pure SSD. My other machine is a 2011 MacBook Pro with SSD and is silent until the fans spin up (ie playing games). At which point the machine is on par with our vacuum cleaner.
So, I found the constant noise of the fusion drive annoying when just word processing etc, 1st world problem I know.
I'm not sure if the noise would bother most people - to be honest, it's not loud but once you are used to an SSD only machine, the noise is noticeable.
Hope this helps people. I've gone with the 256gb SSD and will use Dropbox for long term file storage.
