"Time Capsule HDD replacement" için yanıtTwo years late into the conversation. But, I replaced my 3TB Seagate drive that was in the TC with a 5TB drive (7200). I noticed my backup speed did increase. However I just upgraded it again with the “what the heck...let’s do it” attitude. This time I bought a 'WD EasyStore 8TB external ($149 at Bestbuy) and shucked the case to extract the WD Red 8TB drive. I placed it in the TimeCapsule, formatted it with Airport Utility and pulled the archived data from the 5TB drive. It picked up where it left off and now it is backing up three Macs. One note though. The Red is significantly slower in backup speed. At the same time, the TimeCapsule is running cooler than it did with the 5TB seagate.
