Seagate Backup Plus Slim 4TB STDR4000100

The Backup Plus Slim series of HD are excellent (I have two 2TB and 1 4TB) and affordable. It is certainly not the fastest drive but good enough for my day-to-day archiving purpose as well as running it as a boot disk on USB (even USB 2.0 on a 2009 iMAC (whose internal HD died, and buried inside since I don't want to open the iMAC). Now I can simply take the drive on a trip and boot up any iMAC. The 4TB has the same footprint as the 2TB, only a bit thicker. Please note that there are many Seagate 4TB models, and not everyone is a slim one (the box DOES NOT say it is slim, but it is if you have the Model STDR40000100. I also have the 4TB Backup Hub and it is very bulky in comparison (its advantage is it has its own power and can connect other drives to it). I had the 2TBs for over a year and they perform well. I expect the same for the 4TB. They work for both Windows PC and Macs. However, I find it almost impossible to eject the drives under Windows 10---it is always "in use" (either because of Dashboard, or Windows Backup, or Norton Utility and I have to shutdown the machine to remove it. Very inconvenient. No such problems on a Mac (even if Time Machine is running using a partition on the drive).Read full review
