AMD and Seagate teamed up to demonstrate next-generation transfer speeds based on the latest Serial ATA specifications. The new interface termed as SATA 6Gbps promises to offer twice disk-to-host bandwidth over existing SATA 3Gbps standard. The demonstration was on Seagate's Barracuda Serial ATA-600 prototype hard drive
The demo prototype was based on Seagate Barracuda 7200.12 drive that has a Serial ATA-300 interface. The SATA 6Gbps uses the same SATA 3Gbps connectors despite having fatter pipes.
The prototype Barracuda drive ran on AMD's chipset with a brand new storage controller. According to Seagate, the setup had hit a peak data rate of 589.09MB/s. AMD's south bridge SB750's successor will have full support for SATA 3.0 technology.
The specs include new goodness for a higher throughput peak by 200 percent. Recent destop drives pack 32MB NAND memory chips for supporting larger caches, which will boost the transfer speeds up to 250MB/s. The Solid State Drives on the other hand will move to 64NAND based on 34nm technology.
The SATA 3.0 standard is in final phase of development and isn't available on any product yet. However, Seagate expects to announce products compatible with SATA 3.0 by the year end.
