Why Buy?
4TB of extra space that fits in your pocket
When your laptop keeps warning you it is full, a seagate 4tb hard drive like this one gives you room to breathe without touching your computer's internal storage. It holds years of photos, videos, documents and music, so you stop deleting files just to free up space.
There is no setup to fuss over. Plug the included USB 3.0 cable into your computer and start dragging files across straight away. Backing up a whole photo library or moving a folder of large video files takes moments rather than being a chore you keep putting off. It reads and writes with both Windows and Mac, so switching computers or sharing files with someone on a different system is not a problem.
The compact, lightweight design means it slides into a laptop bag, desk drawer or backpack pocket without adding bulk, so your backup travels with you or sits quietly at home. Seagate backs the drive with Rescue Data Recovery Services, giving you a safety net if the unexpected happens to your files.
Buy this if…
- Your computer keeps running low on storage
- You want an easy backup without paying for cloud storage
- You handle large video or photo collections
- You need storage that travels well for work or study
- You move files between Windows and Mac regularly
