I have - - Mac Pro with ACD, At my home office running OSX. Used as an 'always on' computer, for downloads, storage, surfing, back up. - 15" MacBook Pro with ACD This is my main work computer. Running OSX and Win7. Goes with me everywhere offices, home, travel... (I prefer to work from one main computer, less hassle syncing/juggling files.) - MacBook Air Used as Netbook. Running OSX and Vista. Not used often since my work files are on the 15" - 1 TB Time Capsule - 1 TB Network Hard Drive I'm looking for suggestions on how to 'centralize' my files for easy access and back up. Questions: 1. Central Hard Drive / Server I'd like to store and be able to work on/edit these files from one central hard drive. Also I'd like to be able to access that drive from any computer when traveling. Suggestions on the best way to set that up? 2. In addition of how to set up a central hard drive, which hard drive should I use? The hard drive on my Mac Pro, the Time Capsule HD or the network attached HD, I also have USB 1TB Drives here as well. Thank you.
