I'm trying to decide which to buy tomorrow. I currently use 4 different Portable Hard Drives for my Movie & TV Shows and I want to combine them into 1 or 2 depending which route is better here. I'm looking at either the Seagate 5TB External Desktop Hard Drive which is $129 or the Seagate 4TB Portable Hard Drive which is $119. My question & worries are about life of the drive. I have had good luck with Portables and bad luck with External Desktop Drives. But that was on PC, never have used anything but Portable drives on my Mac in 2 years. Some of the questions I have are will the drive sleep if connected 24/7 to the Mac, and will it wake up randomly like on PC or will it stay sleeping until I open it? Will that keep the lifespan longer? I'm looking to use Plex with my Apple TV which is why I want to combine drives. Just trying to figure out which is the better route & get opinions from everyone.
