Seagate BarraCuda 1TB 2.5" SATA

Seagate BarraCuda 1TB (model ST1000LM048) is a 2.5" internal hard drive designed for laptops and compact PCs, featuring a SATA 6 Gb/s interface. Its slim 7 mm profile and ~90 g weight make it suitable for ultrabooks, external enclosures and small-form-factor builds where high capacity in a small package is required.

The drive offers 1 TB capacity, 128 MB cache and a 5,400 RPM spindle speed, delivering balanced performance for sequential transfers (up to ~140 MB/s) and storage of large media libraries, games or backups. Low idle and read/write power consumption makes it a good choice for portable systems and low-end NAS use.

BarraCuda incorporates Multi‑Tier Caching technology and QuietStep ramp‑load head parking to protect heads during transport and frequent power cycles, improving reliability. Suitable as a laptop upgrade, an additional internal drive in a compact desktop, or installed in a 2.5" bay in a desktop system.
