Travelstar Z7K320

320GB, 250GB & 160GB
2.5-INCH 7mm MOBILE HARD DRIVE

• Low Profile – 7mm thickness for design flexibility
• High Performance – 7200 RPM for faster data access
• Quiet Operation – Enjoy a richer audio-listening experience

Travelstar™ Z7K320 is the industry's first 7200 RPM, 7mm, 2.5-inch hard drive with capacities ranging from 160GB to 320GB. The 320GB per platter one-disk models are designed as a direct replacement for standard 9.5mm HDDs, for use in notebook PCs, external storage and compact systems. The Z7K320 offers design flexibility to accommodate new thinner and more robust devices/systems and delivers up to 18% better application performance than 5400 RPM models of the same capacity.
