Does the Seagate Expansion 16TB work with a Mac?
Yes. The drive is automatically recognized by Mac and Windows with no software install. For Apple Time Machine backups you must reformat it first using Disk Utility.
Do I need to plug this into a wall outlet?
Yes. This is a desktop drive, not a bus-powered portable. Seagate includes an 18W power adapter along with an 18-inch USB 3.0 cable.
What happens if the drive fails and I lose my files?
Seagate includes Rescue Data Recovery Services plus a limited warranty with this model. Check the current product listing for the exact coverage period and terms in your region.
How fast is it, and will USB 3.0 bottleneck it?
It uses a USB 3.0 interface for fast file transfers. Real-world speed is set by the mechanical drive inside, so expect hard-drive rather than SSD performance. Seagate does not publish a rated transfer figure for this model.
