The Seagate Expansion portable drive STKM5000400 adds 5TB of portable storage for a PC or Mac, giving you room to keep large files together and carry them along.
It connects through USB 3.0 and draws power through the USB cable, so it does not need a separate power supply. Seagate describes setup as simple: the drive is recognized by Windows or Mac, with no software installation or configuration required. Files can be saved using drag and drop.
The manufacturer lists compatibility with most Windows and macOS systems, and also names Chromebook compatibility on its product page. The datasheet lists an 18-inch (45.72 cm) USB 3.0 cable, a quick start guide and Rescue Data Recovery Services among the included items; service availability varies by country.
