With these large HDD around, when data backing up times arrive, it would have been nice if the new mainstream HD optical discs (HD-DVD, BluRay) could at least handle 100GB of data per layers (multi layered recordable discs don't count since they're really far away from being available and it will always, well as long a sthe tech is relevant, be cheaper to buy two single layer blank discs than a double layer one).As the second-generation desktop and enterprise perpendicular magnetic recording (PMR) hard drives, the Barracuda 7200.11 and Barracuda ES.2 deliver 1TB of capacity, 7,200-rpm spin speeds, average seek times of 8.5ms, caches up to 32MB and Seagate's five-year limited warranty. Seagate's newest hard drives pack 1TB of data on four discs to provide cool operating temperatures and low power consumption, which help extend drive life.

Another technology integrated into the Barracuda ES.2 is the PowerTrim that dynamically manages drive power consumption at all levels of activity. It's claimed to provide 20% reduction in overall drive power consumption and 55% reduction in watts-per-gigabyte.
The second novelty - Barracuda 7200.11 - supports the highest 105MB/s sustained transfer rate and consumes 8 watts when idle. It also delivers acoustics as low as 2.7 Bels, which is nearly undetectable by the human ear.
The Barracuda ES.2 and 7200.11 will begin shipping in volume during the third quarter. The 1TB Barracuda 7200.11 will be offered at an MSRP of $399.99.
