Storage capacities are going up on traditional hard drives as recording technology gets better. Not so long ago the most storage you could get in a single drive was 1TB and today we can get 2TB HDDs from several manufacturers.
Western Digital has announced a pair of new 3.5-inch 2TB 7200 rpm HDDs today that are called the WD Caviar Black and the WD RE4. Both drives come in 2TB capacity and the main difference between them is that the RE4 HDD is an enterprise version rated for 1.2 million hours MTBF.
Both of the HDDs feature 64MB cache, dual processors for twice the processing performance, dual actuator technology for more accuracy, IntelliSeek to reduce vibration, and Notouch ramp loading technology. Both of the drives use the SATA 3Gb/sec interface.
"WD Caviar Black 2 TB hard drives maximize the features and functionality of power computing applications such as gaming, photo editing, user generated multimedia and video," said Jim Morris, senior vice president and general manager of WD's client storage systems. "With the selection of WD Caviar Black hard drives, WD desktop customers receive the best possible mix of capacity, performance and reliability that is required for intense desktop computing."
The Caviar Black drive will sell for $299 and is available through select retailers now. The RE4 HDD is not priced; WD simply says that the price on it is being qualified by OEMs. That means that the OEM will set the price for the drive when it is put into their systems.
"Specifically designed for enterprise-class applications, WD's RE4 2 TB drives incorporate the best combination of features, optimum performance, and superior reliability that customers have come to expect from WD," said Tom McDorman, vice president and general manager of enterprise storage solutions for WD. "Our enterprise products are directly aimed at customers who require additional features and extensive testing that are necessary for high-end enterprise environments."
In July, Western Digital unveiled the first 1TB 2.5-inch laptop HDD called the Scorpio Blue.
