The short version

One Touch Desktop is Seagate's bus-powered desktop hard drive, sold from 8TB to 24TB and connected by a single USB-C cable, so it needs no wall adapter. That requires a USB-C port delivering at least 15 W, and Seagate warns the drive may not work otherwise. It includes Toolkit software and Rescue Data Recovery Services. It suits laptop users wanting large backups without a power brick, but the 15 W requirement can rule out older ports.

Common questions

Will the One Touch Desktop work from any USB-C port?

Not necessarily. Seagate says it needs a USB-C port delivering 15 W or more and a USB-C data cable, and that the drive may not work if those requirements are not met.

Does it need a wall outlet?

No. Seagate describes it as bus-powered over a single USB-C cable, so the drive runs from the host port as long as that port supplies enough power.
