Seagate is reportedly launching hard drives; namely the Barracuda 7200।11 and the Barracuda ES.2 that deliver up to 1TB of capacity, and that are meant for both desktop PC and enterprise applications. A 3.5-inch format drive, the Barracuda 7200.11 spins at 7,200rpm and holds up to 1TB of data.
This 1TB drive with four 250GB platters that use Seagate's second generation perpendicular recording technology, sports a sustained rate of 105MB/s and a serial ATA (SATA) II interface running at 3GB/s. The 7200.11 has a low power rating of 8 Watts at idle, making for energy efficiency and cooler operation. The acoustics are as low as 2.7 Bels. The other drive, the Barracuda ES.2, is the enterprise version, with improved mean time before failure. The drive, having both SATA and SAS (serial attached SCSI) interfaces, again holds up to 1TB of data. Both new hard drives feature Seagate's power-saving 'PowerTrim' technology, wherein if the drives are reading, separate read electronics can be switched off. Similarly so when the drives are writing... According to Seagate, the power-controlling mechanism within the drives yields up to 25 percent of power saving over say a drive without the mechanism. Seagate said its Barracuda ES.2 and 7200.11 1TB hard drives will begin shipping in the third quarter of this year. The 1TB Barracuda 7200.11 will likely be priced at $399.99 (Rs 18,000 approx).
