Hitachi self-encrypting drives, those with the optional Bulk Data Encryption feature, provide hardware-based data security and enhanced secure erase capability. Self-encrypting drives scramble data using a key as it is written to the disk, then descramble it with the key as it is retrieved, giving users the highest level of data protection available. It also speeds and simplifies the drive re-deployment process. By deleting the encryption key, the data is rendered unreadable, eliminating the need for time consuming data-overwrite.
Hitachi is working with the Trusted Computing Group (TCG) to ensure our products are designed to the TCG Opal industry standard specification. Adoption of the standard brings interoperability and more widespread support.
Benefits
Faster setup time because the drive is built to encrypt data with no feature turn-on required.
Enhanced scalability in multi-drive scenarios because encryption is handled by the drive, eliminating the performance bottleneck of traditional solutions.
Interoperability based on industry standards versus unique chipset and processor solutions.
Portability is improved because there is no system-level dependency-- the encryption engine is inside the drive.
System Performance is improved because the encryption workload is moved off the processor and chipset and onto the drive.
