Actually, SSDs do indeed make a high-pitched noisen when active---at least the ones in my laptop do (two different brands and form factors). The noise is very soft and not really constant, though. It's more a syncopated, staccato "crackling" that sounds like a whine during high I/O, and you aren't likely to notice it unless the rest of the machine (and room, for that matter) is nearly silent. So unless you notice that the tone and rhythm of the sound matches up with the I/O of your system, disk isn't a likely source.

A bit surprising, because I believe SSD's don't have any moving parts. The noise I hear fluctuates pretty wildly, most of the time actually zero, and fairly prominent when I hover on the categories in the Applications menu of Gnome. At the bad moments, it's like a crappy bearing being driven by the creator of hell. If is it is the SSD attached to a SATA3 port, it would be pretty damning because there is hardly any I/O needed to generate the Applications menu listing.
