I have just received an old laptop: HP Compaq 6715b This laptop has no hard drive and I need to buy one. The HDD I buy will depend on the answers I can get here on setting up a NAS. ATM I have a home PC upstairs connected to the netowrk with home plugs. I have the router downstairs which is directly connected to a PS3. I stream from the PC upstairs using PS3 Media server, although some larger 3GB video files tend to stutter when streaming and often I just copy them to a memory stick to play in the PS3. I am wondering what the advantages of using a NAS would be (installing FreeNas to the laptop)? 1. A 500-750GB harddrive would be big enough for all my photos/videos etc, would any HDD do? I read that older laptops (with older chipsets) might not be able to handle bigger hard drives? 2. How would this laptop perform at streaming/serving 1080p/720p video files? Any ideas? 3. I was considering just plugging the laptop directly into the router if using as a NAS. Would this be feasible? 4. Any way to setup VPN access so I can access my data from elsewhere? 5. Anything else I should consider? Any other uses for NAS or laptop? If I don't decide to go for the NAS - I will just buy a cheap 80GB HDD and put Ubuntu on it and use it for surfing etc. Thanks for helping me work this out..
