If you want to use your speedy new SSD to run Hyper-v storage is expensive, Data Deduplication is the solution to this letting you run multiple VMs using the space of pretty much 1 server! It is a feature of Server 2012 that can also be added to Windows .1 with the right know how.
First things first, this feature cannot be enabled on your Operating System partition so you will want to limit your OS partition, you should do this initially when setting up Windows as resizing the SSD to your desired size after installing Windows can be problematic due to data being ‘stuck’. I use 70GB of 256 for my OS partitions and the rest for VMs.
