Until recently I'd never heard of NAS (network-attached storage). I'm used to putting a lot of data on external hard drives, and carrying those with me when travelling or sharing stuff. Since we got 2 iPads and some iPhones at home, I started using Air Video and Zumocast to stream to those devices. Besides that, I use PS3 Media Server to stream to the big screen in the living room. But I noticed my brother asking me to turn on the external HDD, cos he wanted to watch some movies... Then it hit me... what if got myself a NAS, so I can put everything on it and keep it on all the time. It's the best way to share files on a network. I started to surf around the web, and watched some tutorials etc. But I got a few questions left, which are probably better suited for this forum. As you might know, I've an iMac with Mac OS X and Windows 7 via BootCamp. Alongside that, I've created a third partition called Media (exFAT) to share it between both OS'es. Now I'm wondering about the NAS and the file system of it. Can you format the internal HDD of the NAS in any desired file system? Like in my case that would be exFAT... Or do you have to use NTFS? In that case, is it still possible to read and write from Mac OS X? Regarding streaming to iPads and iPhones. Does a NAS support that? I know some NAS support game consoles like the PS3. All in all, I think it would be a great solution for me and stop the need for using multiple external HDD and servers like Air Video and Zumocast. Btw, some NAS have iTunes support. Does anyone have any experience with this? Does it work appropriately? Is it easy to set up?
