The Seagate Mobile 1TB 2.5-inch Internal Hard Drive (Model / Base Number: ST1000LM035 / Part Number: 1RK172-566) is a ultra-slim, lightweight mechanical storage drive engineered for notebooks, thin-and-light laptops, convertible PCs, and portable external enclosures. Featuring an ultra-thin 7mm height profile and weighing only 90 grams, it provides high-capacity primary storage or data expansion for space-constrained computing devices.
Operating on a SATA III 6.0 Gb/s interface with a 5,400 RPM spindle speed and a large 128 MB cache buffer, the ST1000LM035 delivers sustained data transfer rates up to 140 MB/s. Built with QuietStep Ramp Load technology and onboard Rotational Vibration (R/V) sensors, this drive maintains quiet acoustics (2.0 bels typical idle) and operational stability even in multi-drive or mobile environments subject to movement.
Available from DataDive, your trusted technology hardware supplier in Qatar, this original Seagate Mobile HDD is designed for high energy efficiency, consuming just 0.45W in idle mode and 1.6W during active operations. Rated for 600,000 load/unload cycles and high shock tolerance, it offers long-term reliability and silent performance for modern mobile workstations.
