Seagate One Touch 1TB portable SSD

The Seagate One Touch STKG1000400 is a USB-C external solid-state drive offering 1TB of storage for creators and professionals who move large media libraries between Windows, macOS and Android devices. It ships with both USB-C and USB-C-to-A cables for immediate compatibility across modern and legacy ports.

Sustained transfer performance

Rated sequential speeds reach 1030 MB/s over the USB 3.2 Gen 2 interface, allowing extended reads and writes of multi-gigabyte video or photo batches without the slowdown typical of thermal throttling on smaller drives. The NVMe-class controller maintains throughput during long sessions so you can edit directly from the drive.

Thermals and power in daily use

The aluminium enclosure measures 1.97 by 2.76 by 0.42 inches and weighs .16 lb, dissipating heat silently without a fan while drawing power solely from the host bus. No external adapter is required, keeping the setup light for travel and quiet in noise-sensitive environments.

Questions about this item

Does the One Touch SSD get hot or noisy during long transfer sessions?

The drive has no moving parts and draws power only from the USB bus, so it runs silently and stays cool even during sustained 1030 MB/s transfers.

Which cables and ports do I need on my computer to use the STKG1000400 out of the box?

The box includes a USB-C cable and a USB C-to-A cable, letting you connect to either a USB-C or a USB-A port without buying anything extra.

Will this SSD work with my older laptop that only has USB 3.0 Type-A ports?

Yes, the supplied USB C-to-A cable makes it compatible with USB 3.0 Type-A ports, though speeds will be limited to that port's maximum.
