Maxtor Corporation, a worldwide leader in hard disk drives and consumer
storage products, announced today that the company is shipping its
next-generation SATA II and ATA/133 MaXLine® (enterprise applications),
QuickView® (consumer electronics — DVRs and PVRs) and DiamondMax® (desktop)
brand hard drives with a capacity point up to 500GB this quarter. Each brand
leverages a core platform, advanced technologies and design and is optimized
with value-added feature sets for its specific market environments.

“Users and system OEMs continue to define new areas of opportunities for high
capacity disk drives,” said Dave Reinsel, director of storage research at IDC.
“Maxtor’s new 500GB hard drive reflects the company’s continued commitment to
deliver advanced, market-specific storage products and technologies, with
solutions to serve new opportunities in both traditional and emerging market
segments.”

The new 7200 RPM MaXLine Pro 500, QuickView 500 and DiamondMax 11 drives provide
up to a half-terabyte capacity and a 16MB buffer and are available with 3.0Gb
SATA II features including native command queuing (NCQ), staggered spin up,
hot-plug and asynchronous signal recovery.

For the enterprise:

MaXLine Pro 500

Designed specifically for use in multi-drive environments and storage arrays,
the MaXLine Pro 500 drive brings together a host of new advanced features and
technology to help system designers, integrators and IT managers build and
maintain their storage systems. The features are designed to maximize
performance and improve data integrity and ease of use in reference storage,
data protection and cost-sensitive enterprise applications. MaXLine Pro 500
drives must pass Maxtor’s premium test process and are designed to the
enterprise standard of 1 million hour mean time to failure (MTTF) at a medium
I/O duty cycle.

Maxtor MaXLine Pro 500 drives include the following:

— Rotational Vibration Compensation — enables the drive to withstand higher
rotational vibration (25 rads/sec2) from adjacent drives, minimizing performance
degradation caused by excessive vibration in multi-drive environments.
— Accelerated Error Recovery — completes commands within 15 seconds, without
reduced data integrity, making it ideal for RAID applications.
— Expanded Drive Self Test — performs a series of tests to help eliminate
false failures and validate good drives.

Interoperability between Serial Attached SCSI (SAS) and SATA makes the MaXLine
family the ideal complement to Maxtor® Atlas® SAS drives, providing customers
the broadest range of capacity and performance for their enterprise storage
needs. The SAS interface allows SAS and SATA disk drives to be configured in the
same enclosure, enabling customers to mix and match high-performance Atlas
drives with high-capacity MaXLine SATA drives to meet a broad range of price,
performance and capacity requirements.

For Consumer Electronics:

Maxtor QuickView 500

Optimized for high definition multi-stream digital video recorders (DVRs),
set-top boxes (STBs) and DVD/HDD combo devices, the Maxtor QuickView hard drives
marry high-performance and advanced features that result in robust,
industry-leading consumer hard drives for global OEMs and partners. Joining the
Maxtor QuickView 300GB offering, the 400GB and 500GB models bring convenience,
ease of use and an array of AV options to manufacturers looking to maximize the
consumer’s digital experience. As part of Maxtor’s drive testing process,
QuickView hard drives complete an advanced reliability test (RDT) to simulate
operating environments — including temperature and duty cycle profiling.

Maxtor QuickView drives include the following:

— Highest capacity storage — up to 500 hours of standard definition recording
or 89 hours of high definition recording (500GB).
— Latest ATA 7 Streaming Commands — adds powerful capability to manage multi
video streams and enhance AV performance for the best viewing experience.

“Maxtor QuickView hard disk drives offer the most integrated technology for
audio servers and DVRs,” said Bernie Sepaniak, president of Escient. “As Escient
continues to create innovative new products, like our FireBall E2-400 with
Maxtor QuickView high capacity hard drive, performance, reliability, A/V
streaming and Quiet Drive technology packaged under the QuickView brand will
continue to be of great benefit to our customers. We began working with Maxtor
in 2003 and are delighted to count the company as a valued business partner.”

“We are pleased to expand our relationship with Escient to include Maxtor’s high
capacity drives in their next generation products,” said Gary Gentry, senior
vice president, worldwide marketing at Maxtor. “With Maxtor’s leadership, the
strength of MaxLabs® integration services and the solid relationship between our
companies, we are able to provide the highest value and quality.”

For the desktop:

DiamondMax 11

In capacities of 400GB and 500GB, DiamondMax 11 drives are designed for today’s
home and office PCs and are ideal for applications such as desktop business
computing, publishing systems, and multimedia and gaming systems. SATA II
features allow users quicker access to data and faster system performance,
especially for multi-threaded, dual drive/RAID PC applications.

Maxtor DiamondMax 11 drives include the following:

— Leading capacity — provides ample capacity for power-user enthusiasts to
store high volumes of data including music, video, high-resolution images, and
personal and business information.
— Native Command Queuing — intelligently reorders read and write commands to
improve performance.
