Digital ocean offers ssd on all the virtual machines. Uptime is good.

I've never heard of anyone using it for the kind of load you are talking about.  I'm assuming with such a giant load you are making a decent profit.  Buy some hefty hardware and do the architecture properly.  You can rent half a rack at lots of high end datacenters for less than $1000/month.
