However, in this recently published study, Carnegie Mellon University and Facebook take the first large scale and long term look at answering many lingering questions about SSD performance and behavior in the data center.<\/p>\n<p><em>Here are a few key insights from their report:<\/em><\/p>\n<p style=\"padding-left: 60px;\"><b>1.<\/b>\u00a0The failure profile of SSDs differ from HDDs. While HDDs are regarded to have a \u2018bathtub graph\u2019 of reliability where drive failures occur either immediately, or way down the road at the predicted end of their lifespan. However, the reliability graph for SSDs looks different, due to an early period of URE\u2019s (Unrecoverable Read Errors) as faulty cells are detected and flagged. The self-monitoring serves to increase the overall reliability for the life of an SSD.<\/p>\n<p style=\"padding-left: 60px;\"><b>2.<\/b>\u00a0SSDs require a surprising amount of power to run. As power consumption increased, they found a correlation of increased failure rates.<\/p>\n<p style=\"padding-left: 60px;\"><b>3.<\/b>\u00a0Data stored sparsely across the physical drive can lead to higher failure rates.<\/p>\n<p style=\"padding-left: 60px;\"><b>4.<\/b>\u00a0Data writes cause significantly more wear on flash cells than reads. As a result, for write-intensive applications such as logging, HDDs may still be a better choice.<\/p>\n<p style=\"padding-left: 60px;\"><b>5.<\/b>\u00a0Higher operating temps were correlated with increased failures &#8211; more so than with HDDs. These failures can be mitigated by throttling, though early SSDs did not include this functionality.<\/p>\n<p>Some of this information, such as drive wear from writes vs reads, have been know to us for some time. However, other information about temperature based failures and power consumption are very interesting insights.<\/p>\n<p><em>Pogo&#8217;s three main takeaways:<\/em><\/p>\n<p style=\"padding-left: 60px;\"><strong>1.<\/strong> SSD performance is still the number one selling point. Density, environmental conditions, and power consumption are secondary.<\/p>\n<p style=\"padding-left: 60px;\"><strong>2.<\/strong> The number of writes per day matters. Matching an SSD wear level to a specific use case is important.<\/p>\n<p style=\"padding-left: 60px;\"><strong>3.<\/strong> HDDs are not going away. Even with 3D NAND, ultra high capacity HDDs are still going to be the choice for archival storage. This is made even more relevant by the fact that if SSDs are left powered off for even a few months, they can begin to lose their data integrity.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Market_Changes\"><\/span>Market Changes<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>With respect to players in the market, not much has changed. The wave of consolidation is over and three or four\u00a0dominant brands remain in the market. With a few years now to perfect the technology, reliability has increased and performance is more consistent. There are also SATA and SAS options for almost any capacity and wear level that is desired. This has given consumers a lot of choice and driven down costs significantly.<\/p>\n<p>&nbsp;<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_Future\"><\/span>The Future<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>What does the future hold? The big news as we announced in our previous blog post, is the move to 3D NAND. This will provide a huge capacity increase over the existing technologies and should continue to reduce the overall price per GB. SSDs supporting 3D NAND should start shipping later Q4 to Q1 of next year. We are very excited about this development and can\u2019t wait to see capacities in the 10\u2019s of TB!<\/p>\n<p>Last year around this time we also predicted the rise of the NVMe form factor to direct connect SSDs to the PCIe bus of a system. Turns out this form factor has taken much longer to catch on than we anticipated. We still believe that long term this will be the preferred method to attach SSDs to a system. It is very hard to continue to decrease latency in the I\/O sub-system and this is the next logical step. However, there are still very few NVMe SSDs on the market, although most vendors say there will be many more options by the end of the year.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A lot has changed in the SSD market over the last year. Not only do we have a better idea about the long term behaviors of\u00a0SSD drives, prices have dropped and capacities continue to rise. With the announcement of future drives supporting 3D NAND, HDDs will face even more competition. While we still see the need for large spinning disks for archival storage, SSDs are quickly becoming the default option for many applications. The coming year will continue to be an interesting time in the SSD market.<\/p>\n<hr style=\"border: 0; height: 0; border-top: 1px solid rgba(0, 0, 0, 0.1); border-bottom: 1px solid rgba(255, 255, 255, 0.3);\" \/>\n<p><i>To learn\u00a0about how Pogo can help you solve the issues your organization is facing, please call us at 888-828-POGO, or email <a title=\"Sales at PogoLinux.com\" href=\"mailto:sales@www.pogolinux.com\">sales@www.pogolinux.com<\/a>.<\/i><\/p>\n","protected":false},"excerpt":{"rendered":"<p>An update on the state of the SSD Last summer, we brought you \u201cA Brief History of Solid State Drives,\u201d which outlined the evolution of the SSD through the ages.
