Authenticated firmware download, RevertSP

6.7Authenticated firmware download

In addition to providing a locking mechanism to prevent unwanted firmware download attempts, the drive also only accepts download files which have been cryptographically signed by the appropriate Seagate Design Center.

Three conditions must be met before the drive will allow the download operation:

1.The download must be an SED file. A standard (base) drive (non-SED) file will be rejected.

2.The download file must be signed and authenticated.

3.As with a non-SED drive, the download file must pass the acceptance criteria for the drive. For example it must be applicable to the correct drive model, and have compatible revision and customer status.

6.8Power requirements

The standard drive models and the SED drive models have identical hardware, however the security and encryption portion of the drive controller ASIC is enabled and functional in the SED models. This represents a small additional drain on the 5V supply of about 30mA and a commensurate increase of about 150mW in power consumption. There is no additional drain on the 12V supply. See the tables in Section 3.8 for power requirements on the standard (non-SED) drive models.

6.9Supported commands

The SED models support the following two commands in addition to the commands supported by the standard (non-SED) models as listed in Table 6:

•Security Protocol Out (B5h)

•Security Protocol In (A2h)

6.10RevertSP

The SED models will support RevertSP feature where it erases all data in all bands on the device and returns the contents of all SPs (Security Providers) on the device to their Original Factory State.

6.11ATA Security Erase Unit Command on SED SATA drives

The ATA SECURITY ERASE UNIT command shall support both the Normal and Enhanced erase modes with the following modifications/additions:

•Normal Erase: Normal erase shall be accomplished by changing the media encryption key for the drive fol- lowed by an overwrite operation that repeatedly writes a single sector containing random data to the entire drive. The write operation shall bypass the media encryption. On reading back the overwritten sectors, the host will receive a decrypted version, using the new encryption key, of the random data sector (the returned data will not match what was written).

Enhanced Erase: Enhanced erase shall be accomplished by changing the media encryption key for the drive.

6.12Sanitize Feature Set on SED Drives

The drive shall support the Sanitize Feature Set as defined in ANSI/INCITS ACS-2 with the exceptions and/or modifications described in this section.

The drive shall not support the OVERWRITE EXT and BLOCK ERASE EXT sub-commands.

Support of the SANITIZE FREEZE LOCK EXT command shall be determined on a customer-specific basis. OEM drives shall support the command.

ST33000650NS, SED FIPS 140-2 MODEL, ST33000651NS, ST33000652NS specifications

Seagate has long been a leader in data storage solutions, and their range of hard drives, specifically the ST33000652NS, ST33000651NS, SED FIPS 140-2 model, and ST33000650NS, showcases the company’s commitment to performance, security, and reliability. These models are ideal for enterprise applications requiring robust data protection and efficient storage capabilities.

The Seagate ST33000652NS is designed for high-capacity storage, offering 3 TB of space. It utilizes a SATA 6Gb/s interface which ensures rapid data transfer rates, making it suitable for environments that demand quick access to large datasets. Its 7200 RPM spindle speed enhances performance, ensuring that read and write operations are executed swiftly.

Similarly, the ST33000651NS also provides 3 TB of storage but is slightly optimized for different workloads. Both models feature Seagate’s advanced caching technology, which enhances performance by efficiently managing data flow to and from the drive. This is crucial for applications requiring high-throughput operations, such as video streaming and database management.

Transitioning to the Seagate SED FIPS 140-2 model, this drive is particularly focused on data security. The FIPS 140-2 certification indicates that it adheres to stringent federal standards for cryptographic modules, ensuring that sensitive information remains protected. This model caters to government and enterprise clients concerned about the integrity and confidentiality of their data.

On the other hand, the ST33000650NS also features a similar capacity but is geared towards reliability and endurance. It is engineered to endure the challenges of continuous operation, accommodating enterprise environments that require 24/7 accessibility without compromising performance.

All these models come with integrated power management features that enhance energy efficiency, reducing operational costs while minimizing environmental impact. They also utilize Seagate’s innovative technologies for error recovery and data integrity, ensuring users can rely on their performance under demanding circumstances.

In summary, the Seagate ST33000652NS, ST33000651NS, SED FIPS 140-2, and ST33000650NS collectively offer a diverse range of features catered for various enterprise needs. With a strong emphasis on storage capacity, data security, and performance reliability, these drives are well-equipped to handle the intensive demands of modern digital landscapes. Whether looking for high-speed access or enhanced security features, Seagate continues to deliver trustworthy solutions for today’s data-driven world.
