Seagate BarraCuda 1TB 2.5" 5400RPM SATA 6 Gb/s Internal HDD

The Seagate ST1000LM048 is a 2.5 inch internal hard drive that delivers a full terabyte of mechanical storage for laptops and other space-constrained systems. It connects through a SATA 6 Gb/s interface and relies on a 128 MB cache to move data at sustained speeds of up to 140 MB/s, so applications open promptly and large media files transfer with less waiting.

The drive spins at 5400 RPM, a speed that keeps vibration and heat in check while still supplying dependable everyday performance. Seagate incorporates ramp load and QuietStep technologies, so the read/write heads park safely when the system powers down and seek operations stay unobtrusive. These features, together with a rating of 600,000 load and unload cycles, help the drive withstand years of regular use.

Power demands remain modest at just 1.7 W during writes and as low as 0.45 W when idle, an advantage for extending battery life in portable notebooks. The operating range of 32 °F to 140 °F makes the drive a solid choice for home offices, classrooms, field work, or any environment where reliable storage is required.

Installation is straightforward: slide the drive into any standard 2.5 inch bay, attach the SATA data and power connectors, and the system recognizes the additional capacity immediately. Whether you are upgrading an aging laptop, building a small desktop, or dropping a bare drive into a USB enclosure for backups, this model offers an economical path to dependable, high-capacity storage. A two-year limited warranty provides added reassurance.
