I don't know the exact specifics of your a730, but looking online it can be configured with up to a 1TB drive in it. Given the nature of it being an all in one, I would think it is essentially a laptop computer inside a small desktop configuration. What I mean is that since the system can be bought with different size drives, you should be able to upgrade whatever HDD you have in it now to an SSD. How you do that, you will have to consult your owners manuals about that. Additionally, you should check to make sure that such a change to your hardware configuration doesn't void the factory provided warranty if you still have warranty or extended coverage left. But I personally feel confident it can be upgraded.
