Secure solid state drive for embedded applications

Positioned by Microsemi as applicable for situations requiring the highest levels of security and reliability, this low power SSD is designed to offer unmatched security for defence and industrial markets with a compact form factor

The SATA SSDs can be used for industrial, defence, intelligence, unmanned aerial vehicles (UAV) as well as in secure laptops where ultimate security for data-at-rest is required. The low power mSATA SSD has 64 GB single-level cell (SLC) flash capacity in a 50 x 30 mm compact form factor and is 65% smaller than similar 2.5-in. devices. The SSD also features Microsemi’s Armor processor, which the company says solves obsolescence issues common in industrial and defence applications by guaranteeing long-term security and performance.

“Microsemi’s miniaturisation technology coupled with high-end security features in the Armor processor enable customers to design secure systems and reduce the footprint otherwise required,” said Bill Sorrentino, tactical marketing manager for Microsemi's Memory and Storage business. “In the advanced deep sleep low power mode the SSD is only using 150 mW and can be ‘instant on.’ This feature will enable longer field life for battery powered applications. In addition, it will cut down on cooling required for products where heat is a concern.”

The device is Microsemi's newest addition to the advanced TRRUST-Stor family of secure SSDs in a compact MO-300 mSATA form factor. This SSD includes security features such as hardware based AES-256 XTS encryption and advanced key management systems. The Armor III processor also has the capability to sanitise the drive with the NSA 9-12 protocol in less than two minutes, which is up to three times faster than industry standard.

As part of the TRRUST-Stor best-in-class self-encrypting drive (SED) technology, the product offers security that is claimed to be unmatched in a standard mSATA SSD. Advanced key management modes and isolated key fill capabilities protect unpowered data at rest by assuring that the encryption key does not reside in the SSD once power is removed. For sensitive applications, a hardware or software signal can trigger an erase of the encryption key in less than 30 msec. A second security layer can be activated to
