Is there any way to pool more space into the C drive in Windows 8?

I am currently running Windows 8 on my laptop which has a 120gb SSD and a 350gb HDD that is currently just used as an extra drive. Is there any way I can pool the two drives so I just have one large C drive?

Erm you could split that ssd in half with a partition and then use one half for cacheing on the 350gb HDD but it wont be as fast as a dedicated ssdĀ
