The debate between hard drives and solid state drives goes on in 2016, particularly in the area of areal densities – the actual density of storage on a device. Fortunately for us, Tom Coughlin, SNIA Solid State Storage Initiative Education Chair, and a respected analyst who contributes to Forbes, has advised that flash memory areal densities have exceeded those of hard drives since last year!
Coughlin Associates provides several charts in the article which map lab demos and product HDD areal density since 2000, and contrasts that to new flash product announcements. Coughlin comments that “Flash memory areal density exceeding HDD areal density is important since it means that flash memory products with higher capacity can be built using the same surface area.”

A classic case of SNIA Solid State Storage Initiative (SSSI) member collaboration for industry advancement was on display in the SSSI booth for NVDIMM-N demonstration at the Flash Memory Summit (FMS) 2015. Under the direction of SSSI Chair Jim Ryan and coordinated by NVDIMM SIG co chairs Arthur Sainio and Jeff Chang and TechDev Committee chair Eden Kim, the SSSI was able to update and include NVDIMM-N storage performance in the SSSI marketing collaterals on the Summary Performance Comparison by Storage Class charts.
Five SSSI member companies – AgigA Tech, Calypso, Micron, SMART Modular, and Viking Technology – collaborated over a four week period on the introduction of a new NVDIMM-N storage performance demonstration. While it is rare to have potential competitors collaborate in such a fashion, NVDIMM-N storage represents a new paradigm for super fast, low latency, high IO/watt storage solutions. The NVDIMM-SIG has taken a leadership position by evangelizing the technology and developing the industry infrastructure necessary for large scale deployment.
This collaboration highlighted a classic blend of technical, marketing and industry association cooperation.
In the weeks leading up to FMS, the NVDIMM-SIG planned for an in-booth demonstration of the NVDIMM-N storage modules. To pave the way for universal adoption, the team worked together to dial in the Intel Open Source block IO development driver to meet the standards of the SNIA Performance Test Specification (PTS). An added goal was inclusion of NVDIMM-N modules as a new line item on the Summary Performance Comparison by Storage Class chart which lists PTS performance for various storage technologies. Under the guidance of NVDIMM-SIG, a rush project was instigated to get NVDIMM-N performance data tested to the PTS for the trade show.
Micron took the lead by lending a Supermicro server with Micron NVDIMM-N to Calypso for testing. Calypso then installed CTS test software on the server to allow full testing to the PTS. Viking and SMART Modular contributed by helping dial in the drivers, as well as sending modules from Viking and SMART Modular to cross reference with the Micron modules. The test plan was comprised of several test iterations using single, dual and finally quad modules using each of the vendor contributed modules.
The early single and dual module tests ran into repeatability and stability issues. NVDIMM-SIG consulted with Intel on the nuance of the Intel block IO driver while Calypso continued testing. The team successfully completed a test run that met the PTS steady state requirements on the quad module in time to release data for the show.
We had a solid demonstration at the SNIA SSSI Flash Memory Summit Booth on NVDIMM-N Performance complete with marketing collateral available for review and a handout. NVDIMM-SIG members responded to the many questions and interest in the NVDIMM-N storage technology.
“Once again,” said SSSI Chair Jim Ryan, “we can see the value and benefit of SNIA SSSI to its members, the SNIA educational community and the NVDIMM industry. I believe this is a great case study in how we all can contribute and benefit from working within the SSSI for the betterment of individual companies, market development and the Solid State Storage industry at large.” SSSI provides educational and marketing materials free of charge on its public website while SNIA SSSI members may join the NVDIMM-SIG and other SSSI committees. Anyone interested to find out more about the SSSI or any of its many committees can go to the following link http://www.snia.org/sssi.
SSDs present particular challenges when trying to erase all data or attempting to recover data from a broken drive. To address these issues, a new Data Recovery/Erase Special Interest Group has been formed within the SNIA Solid State Storage Initiative.
The goal of the SIG is to provide a forum in which solution providers and solid state storage manufacturers can collaborate to enable data recovery and erase capabilities in solid state storage in such a way as to ensure that customer demands for these services can be met in a cost-effective and timely manner, with a high likelihood of success. A key to the success of the SIG is obtaining input and participation from all of the key stakeholders: solid state storage manufacturers, data recovery and erase solution providers, and solid state storage customers.
The SIG will be having a limited number of conference calls that will be open to non-members. Go to http://www.snia.org/forums/sssi/dresig for more details and to register for the first open meeting.

The SNIA Solid State Storage Initiative (SNIA SSSI) announces a testing service where interested parties may submit their SSD products for testing to the SSS Performance Test Specification.
Any mSATA, SATA, SAS and PCIe SSDs can be tested. The tested device must be recognized as a logical device by CentOS 6.3 and must support Purge (via Security Erase, Format Unit, or equivalent proprietary method of Purge).
Testing is based on the SSS PTS version 1.1. Visit the SSS Performance Test Service page for more information on the tests.
Testing will be conducted by Calypso Systems, a certified SSS PTS testing facility. Participants must submit two (2) samples of the SSD to be tested and provide prepaid return express shipment bills (FedEx, DHL or UPS). Testing will take approximately 3-4 weeks to complete.
Any failed test, or test that will not complete, will be tested twice and error logs will be provided. All product test result data will be kept confidential.
Test results are provided in standard SNIA Report Format as specified in the SSS Performance Test Specification.

SNIA’s Solid State Storage Initiative (SSSI) recently rolled out its new Workload I/O Capture Program, or WIOCP, a simple tool that captures software applications’ I/O activity by gathering statistics on workloads at the user level (IOPS, MB/s, response times queue depths, etc.)
The WIOCP helps users to identify “Hot Spots” where storage performance is creating bottlenecks. SNIA hopes that users will help the association to collect real-use statistics on workloads by uploading their results to the SNIA website.
Using this information SNIA member companies will be able to improve the performance of their solid state storage solutions, including SSDs and flash storage arrays.
How it Works
The WIOCP software is a safe and thoroughly-tested tool which runs unobtrusively in the background to constantly capture a large set of SSD and HDD I/O metrics that are useful to both the computer user and to SNIA.
Users simply enter the drive letters for those drives for which I/O operations metrics are to be collected. The program does not record anything that might be sensitive, including details of your actual workload (for example, files you’ve accessed.) Results are presented in clear and accessible report formats.
How can WIOCP Help You?
Users can collect (and optionally display in real time) information reflecting their current environment and operations with the security of a tool delivered with digital authentication for their protection.
The collected I/O metrics will provide information useful to evaluate an SSD system environment.
Statistics from a wide range of applications will be collected, and can be used with the SSS Performance Test Specification to help users determine which SSD should perform best for them.
How can Your Participation Help SNIA and the SSSI?
The WIOCP provides unique, raw information that can be analyzed by SNIA’s Technical Work Groups (TWGs) including the IOTTA TWG to gain insights into workload characteristics, key performance metrics, and SSD design tradeoffs.
The collected data from all participants will be aggregated and publicly available for download and analysis. No personally identifiable information is collected – participants will benefit from this information pool without comprising their privacy or confidentiality.
Downloading the WIOCP
Help SNIA get started on this project by clicking HERE and using the “Download Key Code”: SSSI52kd9A8Z.
The WIOCP tool will be delivered to your system with a unique digital signature. The tool only takes a few minutes to download and initialize, after which users can return to the task at hand!

SNIA’s Solid State Storage Initiative has just released a revised Client SSS Performance Test Specification (PTS-Client) which adds a new write saturation test and refines existing tests.
The Solid State Storage Performance Test Specification (PTS) is a device-level performance test suite for benchmarking and comparing performance among SAS, SATA and PCI Express SSDs
Revision 1.1 of the PTS-Client updates tests for IOPS, throughput and latency to more accurately reflect the workload conditions under which Client SSDs are used. The PTS-Client v1.1 also adds a Write Saturation test that measures the initial Fresh-Out-of-Box state of SSDs and their performance evolution as data is randomly written to the device.
Eden Kim, Chair of SNIA’s SSS Technical Working Group, describes the primary updates to PTS-Client v1.1 as adjustments to preconditioning ranges and test boundaries. Taken together, these parameters create a repeatable test stimulus that more accurately reflects the workload characteristics of SSDs used in a single user environment The PTS-Client v1.1 also adds an easily understandable description of each test, which helps the user to understand the purpose of the test, the test flow, and guidance on how to interpret the test results.
Sample test results using the PTS-Client v1.1 have been posted to the SNIA SSSI Understanding PTS Performance webpage.
