We had a tremendous response to our webcast asking if we were truly at the end of the 2.5-inch disk era. SNIA Compute, Memory, and Storage Initiative SSD Special Interest Group brought together experts from Dell, Facebook, HPE, JEDEC, KIOXIA, Lenovo, and Microsoft in a lively follow on to the Enterprise and Data Center SSD Form Factor (EDSFF) May 2020 discussions at OCP Summit,. If you missed our live webcast – watch it on demand. Webcast attendees raised a variety of questions.  Our experts provide answers to them here: Q:  SFF_TA_1006 suggests E1.S can support max 25W for 25mm asymmetric heat-sink. What are the air-flow assumptions for this estimate? Are there any thermal models and test guidelines available for EDSFF form-factors? Read More

Are We at the End of the 2.5-inch Disk Era?

The SNIA Solid State Storage Special Interest Group (SIG) recently updated the Solid State Drive Form Factor page to provide detailed information on dimensions; mechanical, electrical, and connector specifications; and protocols. On our August 4, 2020 SNIA webcast, we will take a detailed look at one of these form factors – Enterprise and Data Center SSD Form Factor (EDSFF) – challenging an expert panel to consider if we are at the end of the 2.5-in disk era. Enterprise and Data Center Form Factor (EFSFF) is designed natively for data center NVMe SSDs to improve thermal, power, performance, and capacity scaling. EDSFF has different variants for flexible and scalable performance, dense storage configurations, general purpose servers, and improved data center TCO.  At the 2020 Open Compute Virtual Summit, OEMs, cloud service providers, hyperscale data center, and SSD vendors showcased products and their vision for how this new family of SSD form factors solves real data challenges.
