Seagate announces highest areal density hard drive at 100GB per platter

Seagate introduced the world’s first hard drive to store 100 Gbytes of data on a single 3.5-inch platter. The new addition to the Barracuda 7200.7 family achieves a 200-Gbyte capacity using only two platters, and offers the choice of a Parallel ATA or native Serial ATA (SATA) interface. The Barracuda 7200.7 is the industry’s first hard drive family capable of supporting SATA native command queuing (NCQ). NCQ will be implemented on production Barracuda 7200.7 SATA hard drives when system architectures that support NCQ become more broadly available. NCQ is a feature that can only be implemented on native Serial ATA hard drives like Seagate's.

NCQ technology enables the hard drive to intelligently reorder and optimize both read and write command execution, improving the performance of queued workloads by minimizing mechanical positioning latencies on the drive.
