Seagate Exos 2X18 SATA Product Manual, Rev. A 5
www.seagate.com Introduction
1.0 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.
These drives provide the following key features:

256 MB data buffer.

7200 RPM spindle speed.

Full-track multiple-sector transfer capability without local processor intervention.

High instantaneous (burst) data-transfer rates (up to 600MB per second).

Native Command Queuing with command ordering to increase performance in demanding applications.

PowerChoice™ for selectable power savings

Power Balance supported for limiting max power (See Section 2.5.5)

Perpendicular recording technology provides the drives with increased areal density.

SeaTools™ diagnostic software performs a drive self-test that eliminates unnecessary drive returns.

State-of-the-art cache and on-the-fly error-correction algorithms.

Support for S.M.A.R.T. drive monitoring and reporting.

Supports latching SATA cables and connectors.

T13 Fast Format conversion (see Section 2.2.2 )

Top Cover Attached motor for excellent vibration tolerance

Worldwide Name (WWN) capability uniquely identifies the drive.
NOTE Seagate recommends validating the configuration with the selected HBA/RAID
controller manufacturer to ensure use of full capacity is supported.
