Seagate ST5000LM000 2.5-Inch SATA Internal Hard Drive

Seagate BarraCuda ST5000LM000 is a 5 TB, 2.5-inch SATA hard drive designed for notebook-class storage, suitable for upgrading laptops or serving as the drive inside external enclosures. It uses a 5400 RPM spindle with a 128 MB cache and a SATA 6 Gb/s interface, delivering up to 140 MB/s sequential transfer and supporting 512-byte logical/4K physical sectors (512e). The drive's SMR recording technology optimizes large, sequential writes, while the 15.0 mm form factor, 69.85 x 100.35 mm dimensions, and 190 g weight make it compatible with most 2.5-inch bays. Key physical specs include 5 TB capacity, 5.6 ms average latency, startup current around 1.2 A at +5V, and a voltage tolerance of ±5%, with operating temperature from 0°C to 60°C and non-operating from -40°C to 70°C. The device aligns with the BarraCuda family’s 2.5-inch lineup and is positioned for everyday computing tasks, multimedia libraries, and large local stores where durable, high-capacity mobile storage is needed.
