Toshiba today announced new enterprise-grade SATA SSD models supporting cryptographic-erase and self-encrypting drive (SED) models, one an enterprise SAS solid state drive (eSSD) and the other a mobile SATA hard disk drive (HDD).
Collectively, these four new 2.5-inch storage device models provide both IT system and PC system administrators with more effective tools to help secure sensitive business information.
For the enterprise, the PX02AMU value line of SATA eSSD models and PX03ANU read-intensive line of SATA SSD models feature cryptographic-erase. In addition, the PX02SMQ/U series offers Trusted Computing Group (TCG) enterprise protocol self-encryption and cryptographic-erase support in high-performance eSSD SAS models.
For mobile computing, the MQ01ABU***W series provides self-encryption, cryptographic-erase and TCG-Opal protocol support in a 7 mm height with up to 500 GB of storage capacity. The MQ01ABU***W series also supports Toshiba's wipe technology, which allows systems designers to automatically cryptographic-erase data if an unexpected host attempts to access the HDDs or if a defined number of authentication failures occurs.
These new Toshiba models use government-grade Advanced Encryption Standard (AES) 256-bit self-encryption, and the PX02SMQ/U series SEDs support the TCG Enterprise Security Subsystem Class (SSC) protocols to provide additional security features.
Unlike a regular disk erase, which uses lengthy over-write operations, the Cryptographic-Erase function simply regenerates the SED drive's encryption key, effectively invalidating all previously stored user data. This allows SED storage devices to be quickly and securely sanitized before re-allocation, redeployment or retirement.
The PX02AMU and PX03ANU are SATA MLC SSDs that provide transparent onboard hardware encryption to enable and secure cryptographic-erase using the industry-standard ATA Enhanced Secure Cryptographic Erase function. The PX02AMU has storage capacities of 100 GB, 200 GB and 400 GB, and the PX02ANU includes 55 GB, 120 GB, 240 GB and 480 GB models. Both are suited for entry to mid-range server and storage systems, as well as read-intensive and boot devices for datacenter-optimized servers and scale-out storage systems.
The PX02SMQ/U series is an enterprise-class SAS MLC SSD with available storage capacities of 200 GB, 400 GB, 800 GB and 1.6 TB. Support of both SANITIZE Cryptographic-Erase and the TCG Enterprise SSC makes the PX02SMQ/U series suitable for management and protection of confidential data on mission-critical and business-critical server and storage systems.
The MQ01ABU***W series are 7 mm high SATA 2.5-inch 5,400 RPM HDD SEDs with available storage capacities of 250 GB, 320 GB and 500 GB. Support of both the ATA Enhanced Secure Cryptographic Erase function and the TCG-Opal SSC protocols makes the MQ01ABU series ideal for encrypting and protecting access to confidential data stored on mobile and desktop PCs protected by security management applications.
Toshiba will start shipping samples of the PX02AMU and PX03ANU SATA eSSD drives this month. Sample shipments for the PX02SMQ/U SAS eSSD SED drives and MQ01ABU***W series mobile SATA HDD SED are will begin in the first quarter of 2013.
Self-encryption and other security features are also available on select Toshiba enterprise-class 3.5-inch and 2.5-inch HDD models, as well as select 2.5-inch client SSD and HDD models. Toshiba is also working on FIPS 140-2 certification on select SED products to meet government-class security requirements.
