In a world where digital files multiply faster than laundry, a reliable external hard drive is a lifeline for anyone juggling big projects. Photographers, videographers, gamers and anyone with a full laptop know the struggle of running out of disk space. That’s where the Seagate Portable 4TB External Hard Drive (STGX4000400) comes in, a $99.99 device (down from $124.99) that will keep your data safe and accessible without hassle.
Small and unobtrusive, the Seagate Portable measures 4.61 by 3.15 by 0.79 inches and weighs 9.2 ounces. It fits in a backpack or even a pocket, making it a true travel companion for creators on the go. The black plastic body has a subtle textured finish with a small Seagate logo on top, keeping it sleek without being flashy. A single USB 3.0 Micro-B port on the side and an 18-inch USB Type-A cable in the box. No external power supply needed—power flows through the USB connection, simplifies setup and reduces clutter.

It also works with Xbox and PlayStation consoles, expanding storage for gamers drowning in digital downloads. Some users report compatibility issues with older devices or Macs but those are rare and can be resolved by reformatting.

Performance is where the Seagate Portable shines. With a 2.5-inch mechanical hard drive spinning at 7200 RPM, it delivers up to 120 MB/s read speed, decent for a device in this price range. Transferring large video files or game libraries is quick over USB 3.0 and it stays cool even under load, a bonus for long sessions.

Four terabytes is enough space to hold thousands of high res images, hours of 4K video or a large game library. Specifically it can hold around 800,000 songs or 1,000 hours of HD video. Creators can upload raw film, gamers can carry entire libraries with them, and anyone can backup multiple devices.
