Seagate Momentus Thin Hard Drives
Seagate Momentus Thin 2.5" Hard Drives are a series of high-performance, reliable and energy-efficient hard disk drives designed for laptops, ultrabooks, and other mobile computing devices. They are available in various capacities ranging from 160GB to 500GB and operate at a speed of 5400 or 7200 RPM. The drives use SATA II (3Gb/s) interface for fast data transfer and have a cache size of 16MB or 32MB, depending on the model. They are also built with advanced features such as Seagate SmartAlign technology, which simplifies the installation process and eliminates the need for advanced formatting tools. In terms of physical design, the Momentus Thin drives are ultra-slim with a height of only 7mm, making them an ideal choice for thin and light laptops. They are also shock-resistant and have a low power consumption, which makes them suitable for mobile computing environments. The Seagate Momentus Thin hard drive also features built-in hardware-based encryption using the Advanced Encryption Standard (AES) 256-bit algorithm. The encryption is automatic and transparent, requiring no user intervention to encrypt or decrypt data. In addition to its standard encryption features, the Seagate Momentus Thin hard drive is also certified to comply with the Federal Information Processing Standards (FIPS) 140-2 level 2. This is a US government standard that specifies the security requirements for cryptographic modules used in information systems. FIPS 140-2 level 2 certification ensures that the hard drive meets stringent security requirements, including physical tamper resistance, key management, and other security features. The Seagate Momentus Thin hard drive also features other security features, such as Instant Secure Erase (ISE), which allows for quick and secure deletion of all data on the drive.
Key Advantages
- 7mm z-height form factor enables thin chassis design for all segments of laptop computing.
- Seagate SmartAlign technology provides a transition to 4K sectors without the need for software utilities.
- Self-Encrypting Drives mitigate data breaches, comply with data protection regulations and preserve brand recognition.
- Self-Encrypting Drives with FIPS 140-2 certification are approved for the U.S. and Canadian governments.
