Using network harddrives

Hey,
I've using Serviio from my laptop to stream content to my Sony EX72X TV. I've upgraded to a SSD system which limits the space on my laptop hard drive so I need to consider external hard drives to bring additional space. As I'm mostly using my laptop I'd like to continue keeping things wireless, so network (NAS?) drive comes to play. Obviously it would be ideal to have a dedicated NAS drive running Serviio, but my budget is kinda limited so I'm thinking about getting a cheaper one not capable of running Serviio on it self.
So far streaming from my laptop to a TV has worked fairly well. I mostly have content in 720p w/ bitrate of ~4500 kbps. How much, if at all, would the network drive vs laptop hdd affect to the streaming performance? Would it be roughly the same as now with a cheap network drive or do I need to consider a more expensive NAS drive w/ dedicated Serviio server?
