Hey guys, I recently upgraded my MacBook's memory to 500GB, which means it's time for a new external for Time Machine backup. My only requirements are that it's something reliable that I'll be able to use for this computer as well as my next (since I may be getting a new one within the next two years). I know things get tough transferring data between hard drives (experiencing that now trying to load some of my old stuff onto my new drive), so if there's any type in particular that works best for transferring, please let me know. I'm looking at 1TB Western Digital models right now, trying to keep the price range around $100 if possible, but I wouldn't mind spending a little more if it means not having to worry about buying a new one for a few more years. Thanks in advance for the help.
