SCSI Hard Disk Drives

ENTERPRISE

Exceptional Performance

Ultra320 SCSI with AAF, Packetization and QAS for faster overall system performance and data reliability 4.5 ms seek time Large 8 MB cache buffer Maximum sustained interface transfer rate up to 55MB/sec High performance Atlas architecture that is ideal for cluster server environments
Industry-leading Performance for the Most Demanding High Bandwidth Applications

Setting the Standard

Introducing Atlas 10K III-Ultra320, the next generation Maxtor SCSI hard disk drive providing full implementation of all mandatory and optional Ultra320 SCSI interface features as defined in T10/SPI-4 rev. 9 draft standard. These features include Adaptive Active Filtering (AAF), Packetization and Quick Arbitration and Selection (QAS). Adaptive Active Filtering is a Maxtor technology innovation that allows the drive to adapt to changing system configurations and components while optimizing signal quality. This translates into lower error rates, easier integration, and increased bus efficiency for optimal system performance. Ultra320 SCSI provides the highest ever data bus bandwidth and is designed to handle the most demanding enterprise server applications.
Best-Fit Enterprise Applications
Enterprise computer users will now have faster, more reliable data transfer rates for optimal use in: multi-stream video and audio, data warehousing applications, web servers, RAID applications, large file transfers, non-linear editing, high-end graphics, electronic cinema, scientific data processing, video servers, image processing, high definition play back, super computer, and 3D animation.

Proven Full Inter-operability
The Atlas 10K III-U320 has proven full inter-operability with major SCSI and SCSI RAID controller manufacturers and it is backwards compatible with prior SCSI interface standards.
Atlas 10K IIIU320 and the Need for Speed
Maxtor continues to innovate and provide state-of-the-art solutions to its customers. Ultra 320 SCSI widens Maxtors SCSI leadership. Ultra 320 SCSI is the latest evolution of SCSI and takes drive performance and reliability to the next level. As a rule of thumb, Bus Bandwidth needs to be 4X the drive throughput to attain optimal system performance Ultra 320 SCSI makes it possible! Best-in-Class HDD max sustained interface transfer rates: 199928 MB/sec, 200042 MB/sec, 200155 MB/sec One Atlas 10K III drive can sustain 55 MB/sec peak data rate throughput. Therefore, as few as three drives can saturate an Ultra160 bus limiting your system performance.

The Ultra320 Advantage

Ultra 320 SCSI provides optimal system performance, extending your system advantage beyond 2003. Atlas 10K III-Ultra320 provides all the advantages of the Ultra320 SCSI standard. Features like: free-running clock, training pattern, skew compensation and Adaptive Active Filtering (AAF), Packetization provide unsurpassed data and signal integrity. Quick Arbitration and Selection (QAS) and Flow control optimize system performance. These features are only available with the Ultra320 SCSI standard and the Maxtor Atlas 10K III-Ultra320.

Adaptive Active Filteringthe Maxtor Advantage
Maxtors Atlas 10K III-U320 AAF implementation improves signal integrity and as a consequence maximizes system performance. Signals with AAF are crisper and have a better peak-to-peak amplitude definition. AAF enhances electrical signal margins
