IBM today introduced the world's
fastest desktop hard disk drive with IBM-exclusive technology called "tag
'n seek" for its childlike simplicity. Known technically as tagged command
queuing, "tag 'n seek" technology enables the new IBM Deskstar 180GXP to
perform up to 20 percent faster than its competitors. IBM begins shipping

The new 180GXP is a 7200 RPM drive and features a fourfold increase in
cache size - up to 8 MB - for increased data throughput and user
productivity. It has a maximum capacity of 180 GB and offers customers a
broad range of options at 30, 40, 60, 80, 120 and 180 GB.
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
