Seagate BarraCuda 2TB 2.5" 5400RPM SATA Internal HDD

The Seagate ST2000LM015 is a 2TB internal hard drive that brings dependable storage to laptops and other small form factor systems. Built around the well-known BarraCuda platform, it offers a spacious capacity without requiring much physical space, so it suits thin notebooks, mini PCs, and external enclosures where every millimeter counts.

Its 2.5-inch design with a 7 mm height connects through a SATA 6 Gb/s interface and spins at 5400 RPM. In everyday use, the drive can move data at up to 140 MB/s, giving you noticeably quicker file transfers and shorter application load times compared with older, slower laptop drives. Whether you are expanding a photo library, storing large project files, or keeping a growing collection of games and media, the generous capacity means less juggling and more doing.

Because the drive is engineered for low power draw and minimal heat, it helps prolong battery life in portable systems and keeps compact desktops running quietly. At about 90 g, it adds very little weight, making it an easy upgrade for travelers, students, and professionals who rely on mobility yet still need plenty of local storage.

Installation follows the standard SATA procedure, so most users can swap it in with a simple screwdriver. Once installed, the drive works seamlessly with Windows, macOS, and Linux after formatting, letting you get back to work, play, or creation with a larger digital workspace at your fingertips.
