The Momentus family of 2.5-inch laptop drives offers innovative
options and features, such as capacity up to 750GB, two different
performance speeds, and three significant features.

Key Features and Benefits
- Seagate SmartAlign™ technology provides a transition to 4K sectors without the need for software utilities.
- Seagate
Self-Encrypting Drives deliver government-grade encryption without
performance degradation—protecting your data where it lives. The FIPS
140-2* options are NIST government-certified for both U.S. and Canadian
usage with sensitive data.**
- Seagate G-Force Protection™
technology can detect when your laptop is in a free-fall, swing the
drive heads to a safe zone and keep the data safe.
- 7200-RPM and 5400-RPM speeds for customized performance, and 8MB and 16MB cache size to enhance your application performance
- 750, 640, 500, 320, 250 and 160GB models for 5400-RPM drives for high-capacity to entry-level and mainstream systems
- 750, 500, 320, 250 and 160GB models for 7200-RPM drives for high-capacity and high-performance systems

Seagate Cheetah 15K drives offer the high performance, increased
capacity and optimized power consumption needed by enterprises to meet
demanding Tier 1 enterprise requirements.
Key Features and Benefits:
- Delivers high performance with sustained data rates up to 171MB/s*
- Offers high capacity (up to 600GB) with third-generation perpendicular recording*
- Includes Seagate PowerTrim™ technology to dynamically reduce power usage*
- Supports 6Gb/s SAS 2.0, 4Gb/s FC, and Ultra320 SCSI interfaces*
- Includes
advanced read/write technology for an unrecoverable error rate of
1x10E16 and an annualized failure rate (AFR) of 0.55 percent
- Provides
TCG-compliant, Self-Encrypting Drive (SED) security option (SAS models
only) to eliminate the need to overwrite or physically destroy drives,
enable safe return of drives for warranty or expired lease purposes and
allow organizations to securely repurpose or sell hard drives*
