IBM's performance-enhancing technology -- "tag 'n seek" -- is a method of controlling commands sent from the host processor to the hard drive, enabling faster application activities for the end user. "Tag 'n seek" tags each command that arrives at the drive's buffer with an identifier, then reorders and processes the commands in the most efficient manner. This enables commands to be more quickly processed, minimizing seek time and freeing the host processor to handle other critical activities.
Avid Technology, the global industry standard for digital media post-production and distribution, uses the 120 GB Deskstar hard drive within its Avid Unity(tm) LANshare EX shared-storage solution. This is a cost-effective and high-performance media network that offers configuration flexibility, massive capacity and data protection designed for the unique demands of digital editing.
"Digital video editors require tremendous storage capacity and high throughput in order to reliably access their media on-demand," said Lesley Gloriso, product marketing manager, Avid Technology. "Our experience with IBM's 120 GB Deskstar hard drives is strong evidence that this new technology will continue to deliver the high capacity, industry-leading performance and reliability post-production professionals expect from their digital media solutions."
IBM's focus in advancing performance is based on the belief that speed is becoming the key metric for technology leadership in desktop hard drives. While areal density advances have enabled hard drive capacities to increase 100 percent each year, performance improvements have lagged at just 10 percent a year. IBM's "tag 'n seek" technology is a key performance-enhancing technology that will help close the technology gap between capacity and performance.
"The performance of the new Deskstar 180GXP gives our customers a strong foundation for differentiating their products from competitors," said Robert Holleran, business line executive for Deskstar products, IBM Storage Technology Division. "Customers can rely on the 180GXP's focus on top performance to help manage the emergence of storage-intensive digital applications that also have demanding workloads."
In addition to industry-leading performance and data throughput, the Deskstar 180GXP features the lowest power consumption and heat emission of any high-performance desktop drive to date. The Deskstar 180GXP also implements spindle motors with fluid dynamic bearing across the entire family, significantly reducing acoustic noise.
The new-generation Deskstar is positioned to excel in emerging desktop applications, such as gaming and nonlinear digital and audio/video recording and editing. The drives also provide a cost-effective alternative to tape for data backup, enabling high-performance disk-to-disk backup and recovery.
The Deskstar 180GXP's high capacity and performance offerings are backed by IBM's renowned Systems Integration Test (SIT) Labs and worldwide distribution support.
