I need to upgrade my internal TimeMachine drive to a capacity of 8TB (I know about the drawbacks of an internal backup drive, but I also have several clone backups, some off-site) and would like to avoid a RAID. Since TM can only use a single drive, my only other option is to get an 8TB drive. The only internal 8TB consumer drives on the market seem to be the Seagate Archive and the WD Red. The Seagate drive uses SMR, which has some drawbacks, and the WD drive is meant for use in a RAID system, not as a single drive in a desktop. Which one would you choose?
