For the past few weeks, there has been quite a commotion on tech sites, and it was all because of a 5 year old presentation. Someone discovered a set of slides created in 2010 by then-chair of the JEDEC SSD committee, Alvin Cox of Seagate. That person misinterpreted one of the slides to mean that unpowered SSDs would retain data for only a few days in a hot room. It was reported on one site and of course picked up by several others, spreading quickly across the spectrum of sites reporting on technical matters. Finally, Alvin and a colleague gave an interview to PCWorld (www.pcworld.com/article/2925173/debunked-your-ssd-wont-lose-data-if-left-unplugged-after-all.html) setting the record straight, stating that a scenario that might cause data loss is highly unlikely, especially for consumers. Read the article for more details.

At the most recent Flash Memory Summit in August 2014, the SNIA NVM Programming Model was selected for a singular honor – industry recognition as a Best of Show for Enterprise Business Applications. Being recognized was quite unique, as the Model is not a product or a solution as were other winners in the various categories; but rather a body of work that defines new software programming models for non-volatile memory, also known as NVM.
NVM technologies are currently advancing in such a way as to blur the line between storage and memory – which will radically transform the way software is written. The NVM Programming Model embraces this transformation, describing behavior provided by operating systems that enables applications, file systems, and other software to take advantage of new NVM capabilities.
The Model addresses NVM extensions for existing devices such as SSDs and persistent memory, describing the differences between software written for block storage (SSDs and disks) and persistent memory, and outlining the potential benefits for adapting software for persistent memory.
In presenting the Award to Doug Voigt, co-chair of the SNIA NVM Programming Technical Work Group, Jay Kramer, Chairman of the Flash Memory Summit Awards Program and President of Network Storage Advisors Inc., stated, “Flash memory technology is currently experiencing a progression of innovations that can make a real difference in solving storage solution challenges. The industry is seeing a proliferation of new Non–Volatile Memory (NVM) functionality and new NVM technologies. We are proud to select the SNIA NVM Programming Model for the Best of Show Award as it brings to the marketplace a new standard with a model that defines recommended behavior between various user spaces and operating system (OS) kernel components supporting NVM.”
Congratulations to the many SNIA member company contributors to the Programming Model for this honor! For information and to download the specification, visit http://www.snia.org/forums/sssi/nvmp.

The SNIA Solid State Storage Initiative (SNIA SSSI) is working to better understand disk drive use in everyday computer actions. You can help by participating in our Workload I/O Capture Project – WIOCP – and get rewarded!
The WIOCP captures I/O statistics unobtrusively and without compromising your PC’s performance. No personal data or content is captured – only statistics on the types of data transfers that occur. This helps the SNIA SSSI and the industry understand what actually takes place with your drive when you use your PC.
Collecting I/O statistics helps computer scientists determine the type of workloads your drive is experiencing. By capturing statistics from a large number of computer users, designers can optimize both the drive and the host computer system to improve your overall computing experience. You can be a part of history!

The SSSI has launched the SSD Features Rating project – intended to provide a better understanding of what users expect of their SSDs.
Understanding which attributes are most important in applications will help SSD manufacturers to design products more suitable for those applications, and will provide guidance to users looking for the best SSD for their application.
The first step of the project is a survey which asks SSD users to rate the importance of various SSD attributes/features. SSSI plans to announce the results of the survey at the Storage Visions conference on January 5-6, 2014.
The survey is now open and will close on November 28. Survey results will be posted on this page after the conference.
Join our LinkedIn Group: SSDs – What’s Important to You? to contribute to the discussion!

A new revision of the Enterprise Solid State Storage Performance Test Specification (PTS–E 1.1) is now available for public review. The PTS is an industry standard test methodology and test suite for the comparison of SSD performance at the device level. The PTS–E 1.1 updates the PTS–E 1.0 released in 2011 and adds tests with specific types of workloads common in the enterprise environment. The PTS–E 1.1 may be downloaded at http://www.snia.org/publicreview.
“The PTS–Enterprise v1.1 provides both standard testing (IOPS, Throughput, Latency, and Write Saturation) as well as new tests for specific workloads commonly found in Enterprise environments,” said Eden Kim, Chair of the SSS Technical Work Group. “These new tests also allow the user to insert workloads into the new tests while maintaining the industry standard methodology for pre conditioning and steady state determination.”
The new tests target workloads common to OLPT, VOD, VM, and other enterprise applications while paying special attention to the optimization of drives for varying demand intensity, maximum IOPS and minimal response times and latencies.
