■

This second-generation, 15K-RPM drive has seek times at 3.6 msec and access times at 5.6 msec—30 percent faster than the 10K-RPM drives.

■

We launched the first generation Cheetah X15 in June of 2000. Secondgeneration technology is backed by successful major OEM qualifications, one-year of successful field results and customer satisfaction.

■

The Cheetah X15 holds the industry’s highest reliability rating at 1,200,000 hours MTBF and at 0.73 percent AFR.

■

Adopted by most major OEMs, the first-generation Cheetah X15 was the most awarded and acclaimed Seagate drive ever.

CHEETAH X15-36LP

Capacities in the sweet spot of the market Up to 320-Mbyte-per-second transfer rate. Includes packetization and QAS. Fully compatible with Ultra160. Seagate’s FC experience and robust drives make it the number-one choice of major OEMs.

Economies of Speed for Transaction Processing

Up to 40 percent more IOPS than the new generation 10K-RPM drives. Achieves rapid access to data with fewer drives than 10K. Performance is maximized with Seagate’s advanced caching and command-queuing algorithms and Seagate’s superior adjacent-track seek performance. SAMS keeps performance on track by reducing the impact of rotational vibration in multidrive environments. 41 percent faster transfer rate than the Cheetah X15. Enhanced with Seagate’s Nonlinear Optimized Formatting.

Areal Density is maximized with Seagate’s Zero Acceleration Path enhanced track spacing, allowing for a lower disc and head count bringing greater reliability.

Seagate has proven reliability leadership with its first-generation Cheetah X15. Highest reliability rating in the industry. Incorporates the most advanced elements of 3D Defense.

Seagate’s sound barrier technology ensures whisper-quiet acoustics. Temperature sensor warns host when the temperature exceeds limits. 3D Drive Defense’s SeaShell brings the nonop shock to over 1,000 Gs.

Power is within the envelope of 10K- and 15K-RPM products.

Seagate’s Customer Service: rated above average to excellent by 95 percent of the 2,000 customers surveyed who used Seagate’s service. Seagate’s team brings superior breadth and depth of experience to you. In the complex world of storage design, support is often the deciding factor.
