Travelstar™ Z7K500 is the second generation 7mm, 7200 RPM 2.5-inch hard drive from HGST, with capacities ranging from 250GB to 500GB leveraging Advanced Format, which increases the physical sector size from 512 bytes to 4,096 (4K) bytes to improve drive capacities and error correction capabilities. Travelstar Z7K500 is the first 2.5-inch HDD with a 6Gb/s SATA interface and 32MB of cache and delivers the highest 7200 RPM performance in PCMark Vantage testing. The 500GB per platter, one-disk models are designed as a direct replacement for standard 9.5mm HDDs, for use in notebook PCs, external storage and gaming consoles, as well as new, thinner and more robust device designs.
