Datalight Announces File Level Secure Delete on e•MMC 4.4x
Santa Clara, CA (Flash Memory Summit), – August 9, 2011 – Today Datalight announced its Reliance Nitro File System will be the first product to offer software support for file level secure delete, utilizing features defined by the e•MMC 4.40 and 4.41 specifications. The secure delete feature in Reliance Nitro purges all the file data, including any hidden copies created by the file system to safe-guard reliability, when a file is copied or altered by the file system to ensure a completely secure erase. Assuming the complimentary hardware support, users can be confident that every instance or fragment of a file will be permanently deleted and therefore unrecoverable.
A recent study1 by the University of California, San Diego Non-Volatile System Laboratory highlights the challenges of effective deletion of secure data. UCSD researchers found that measures employed in SSDs and other flash arrays “produce copies of the data that are invisible to the user but that a sophisticated attacker can recover.” Their analysis concludes that “Sanitizing storage media to reliably destroy data is an essential aspect of overall data security.”
“Over the years, many of our customers have asked for secure delete capability,” said Roy Sherrill, Datalight CEO. “The UCSD study illustrates just how vulnerable users of flash memory are to data security breaches, and highlights the urgency for the implementation of secure delete in the industry. The secure operations features of e•MMC give us the hardware foundation we’ve been waiting for to deliver a robust solution.”
The e•MMC 4.41 secure operations comprise two features: secure erase and secure trim. With
the latest release of Reliance Nitro, users will be able to flag critical files as "secure". Internally,
the Datalight file system will then utilize these secure operations to permanently erase
fragments and backups of those files.
“Secure delete is the first of many features we plan to introduce in support of e•MMC between
now and 2012,” said Datalight VP of Engineering, Ken Whitaker. “e•MMC 4.41 and 4.5
specifications contain a slew of incredible performance and feature enhancements, and
Datalight will be the first to offer software support for OEMs and their customers.”
Support for secure delete is just one part of the company’s initiative to provide software support
for JESD84-B45, Embedded Multi-media Card (e•MMC), Electrical Standard (4.5 Device),
recently published by JEDEC. The new JEDEC e•MMC (4.5) standard makes it easy to embed
mass-storage flash memory on host systems. The standardized eMMC protocol is the choice for
today’s smart phones and tablets, and the interface offers designers high performance and
keeps technology complexity invisible to the host.
The company plans to release the new e•MMC-optimized software products for Android, Linux
and other embedded operating systems in 2011.
