# You Won’t BELIEVE What a Terabyte Actually Contains: The Surprising Truth About Digital Storage When you upgrade your hard drive, expand your cloud storage, or purchase an external SSD, you often hear the whimsical claim: “A terabyte (TB) equals 1,000 gigabytes!” But what does a terabyte really contain, and why does it feel so much bigger than expected? In this article, we’ll peel back the layers and reveal exactly how much digital space a terabyte holds—and why it’s far more than just numbers on a drive. ## What Exactly Is a Terabyte?
