The Seagate 3D Defense System™—No One Does More to Protect Your Drives

Drive Defense

■

SeaShell™packaging protects drive against 1,000 Gs of nonoperating shock.

■

Enhanced G-Force Protection provides new mechanical features that further protect the drive from nonoperating shock.

Data Defense

■

ECC (error-correction code) performs on-the-fly hardware correction for excellent performance.

■

Safe Sparing ensures the drive will return to the same sector after a power outage.

■

CBDS (continuous background defect scanning) proactively identifies and eliminates defects.

Diagnostic Defense

■

SeaTools Suite diagnostic software is designed to reduce drive returns, decrease drive repair costs and protect data.

■

Web-based tools enable users to identify and solve common system-related issues.

■

Enhanced S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) predicts and prevents problems transparently before they affect the end user.

■

Enhanced Drive Self-Test (NDST) reduces diagnostic time.
