(Note: This is mostly a hardware question, but I'm posting it here because I'm only concerned with how it applies to AppleTV) Hi all, I'm doing some cost analysis for setting up a home with video streaming via iTunes and AppleTV. One thing I am taking into consideration is outfitting the home's PC with a Terabyte drive or two for media file storage. My question is this: taking reliability into account, what would be the best speed for the hard drive? My gut instinct is always to grab the fastest drive available (prob. 7200rpm), but faster drives tend to encounter more issues down the road. So, I could go with a more conventional 5400rpm, but will that be fast enough to stream a full movie? If I have files that are 1, 2, or even 3 gigs of data in size, will I be bottlenecking things if I use a 5400rpm drive? The connection would be Wireless-N, with little interference over fairly short range. I'm mostly looking for personal experiences. Has anyone using a similar setup found issue with using a less than 7200rpm drive?
