hmmmm, i have not yet experimented with an ssd, but i've read that it's
advised to disable swap because heavy reads/writes kill the thing. the
information was in regards to using an ssd on a netbook running linux -
(for example running windows on the netbook with an ssd is certain
death, unavoidable doom - as you probably know windows machines read and
write to the disk like there's no tomorrow, and for no real good reason
- they swap just for the heck of it, even just turning the thing on it
starts swapping)

so... it would make sense to me that you're going to experience troubles
running a high traffic cache on an ssd.
