Industry-leading Speed and Reliability Improved with Ultra320 SCSI Interface
on Maxtor's Atlas 10K III and Adaptec's SCSI and RAID Products

Maxtor® Corporation (NYSE: MXO), a worldwide leader in hard disk drives and storage solutions, today announced it is working with Adaptec (NASDAQ: ADPT), the global leader in data storage access solutions, to deliver full interoperability between Maxtor's Atlas 10K III SCSI hard disk drives and Adaptec's Ultra320 SCSI and RAID controllers for state-of-the-art storage applications.

Ultra320 is at the leading edge of SCSI interface technology for enterprise computer users, delivering up to double the data transfer rates of the Ultra160 interface and offering backwards compatibility with all previous generations of the SCSI interface. Ultra320 is optimal for data transfer in mainline storage; NAS, SAN and RAID environments; and streaming video and audio applications.

The relationship between Maxtor and Adaptec assures our customers that the two companies are working closely together to offer complete and compatible products, said John Joseph, vice president of marketing, Server Products Group at Maxtor. IT managers can rest assured that the reliability and performance promised by the latest Ultra320 technology through faster data transfer rates is achievable through Maxtor's Atlas 10K III Ultra320 and Adaptec's Ultra320 controller cards.

The announcement comes ahead of the European press launch of the Atlas 10K III. Review units of Maxtor's Atlas 10K III Ultra320 are expected to be available in November 2001 and volume shipments will begin in early Q1 2002.

The Atlas 10K III Ultra320 is a 10,000 RPM SCSI drive offering full implementation of the mandatory and optional Ultra320 SCSI interface features as defined in T10/SPI-4 rev 7 draft standard, including adaptive active filtration (AAF). Maxtor's AAF technology option improves signal integrity over previous SCSI drives by allowing the drive to adapt to changing system configurations and components. It simultaneously optimises signal quality to lower error rates and increase bus efficiency and system performance. Offered in 18 GB, 36 GB, and 73 GB capacities, Maxtor's Atlas 10K III is the ideal choice for enterprise-level applications such as streaming multimedia, high-volume network servers, and RAID configurations. The disk drive has an average seek time of 4.5 ms and industry leading 18 GB/platter density.

Adaptec is pleased to be working with Maxtor on bringing this next-generation SCSI technology to market, said Lee Caswell, vice president and general manager of Adaptec's Storage Solutions Group. Customers will benefit from two leading suppliers working to smooth the transition to Ultra320 technology, which will speed time to market for early adopters.

The heart of Adaptec's Ultra320 offering is the AIC-7902, a dual-channel Ultra320 SCSI ASIC with integrated support for hardware mirroring. The product's unique Gatling" technology allows each channel to be used completely independently, giving system OEMs flexibility in designing low-cost integrated RAID on motherboard or zero-channel solutions. The forward-compatible path from the AIC-7899W to the AIC-7902 allows for easy migration from Ultra160 to Ultra320. Caswell added that Adaptec expects merchant motherboard suppliers to move quickly to Ultra320, upgrading the broad range of Adaptec RAID-ready platforms in the field.
