The ST1000LM049 from Seagate is a 1TB BARRACUDA 2.5-inch hard disk drive spinning at 7200RPM with a SATA III interface. It carries a 128MB cache, uses shingled magnetic recording with a 512e sector size, and sustains data transfer at 160 megabytes per second. The ST1000LM049 draws 1.7W when active and 0.7W at idle, produces 24dB of acoustic noise, and operates from 0°C to 60°C.

A 2.5-inch mobile hard drive trades the speed of flash for a much lower cost per terabyte, which keeps it relevant wherever bulk capacity matters more than access time. The ST1000LM049 is used in notebook and all-in-one upgrades, external and portable USB enclosures, home surveillance recorders, and secondary bulk storage alongside a smaller boot SSD. Shingled magnetic recording overlaps adjacent tracks to raise areal density, so this drive suits read-heavy and archival workloads rather than sustained random writes. Consumers, repair shops, and system builders are the typical buyers.
