Will SSD/RAM disk get me sub 1 second?

Your first byte times on all of the responses looks to be about the same as the RTT to the server so throwing more hardware at it won't fix the problem. Your best bet is to optimize the front-end resource loading.

Using a CDN (there are inexpensive and free options) will reduce the time to load each of the resources.

If you can move as much of your javascript out of the head as possible it will also help (understanding that modernizr still needs to be loaded in the head). This is one area where Chrome is in a bit of flux with it's prioritization though because it will take blocking script tags from anywhere in the document and prioritize those requests and block images until they complete. If you can use Modernizr's loader to load the rest of the javascript asynchronously then the images should start downloading sooner for all browsers.
