The Western Digital 1TB Scorpio Blue Internal Hard Drive (2.5”) is designed for use in portable computing solutions, and features a 3 Gbps SATA interface, 5400 RPM rotational speed, and 8 MB buffer size. It can transfer data at speeds up to 3 Gbps (buffer to host) and 150 MB/s (host to drive). In addition, the hard drive offers 5.5 ms average latency and 4 sec average ready time.
ShockGuard technology protects the drive mechanics and platter surfaces from shocks. WhisperDrive technology makes use of seeking algorithms to minimize operational noise. A shock rating of 400 G operating and 1000 G non-operating makes the drive capable of withstanding accidental drops.
The SecurePark feature safely parks the recording head and keeps it away from the disk surface during spin up, spin down, and when the drive is off, thereby ensuring long term reliability and improved non-operational shock tolerance. Advanced power management features save power and improve battery life. In addition, the Scorpio Blue internal hard drive incorporates Advanced Format technology that increases media format efficiencies, allowing for larger drive capacities.
