Introduction

This manual describes the functional, mechanical and interface specifications for the following:
Seagate® Exos® 2X18 SATA drive models.
Exos 2X18 enterprise dual-actuator hard drives utilize MACH.2™ technology, enabling up to 2x the performance of an
enterprise single-actuator 3.5-inch hard drive. MACH.2™ technology increases performance in a single hard drive by
using two independent actuators that can transfer data to the host computer concurrently. 18TB of capacity is
presented to the host system as one device with the first 50% of the LBAs mapping to the primary actuator, and the
second 50% of the LBAs mapping to the secondary actuator, allowing the user to increase performance while
effectively using the full capacity of the drive. Exos 2X18 drives provide high performance, high capacity data storage
for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers.
