The Dell EMC SC5020 makes storage cost savings automatic with a modern architecture that optimizes your data center for economics while delivering transformational SSD, HDD or hybrid performance. SC Series provides the lowest effective $/GB for flash and hybrid flash, giving companies of any size the technology advantage they need to compete in today’s fast-changing markets.
Source: Dell internal analysis, April 2017. Net effective capacity after 5:1 data reduction including 5 years of 7x24x4hour on-site support as compared to other midrange storage from major-vendors when using the same mix of SSD and HDD capacity. Customer’s price may vary based on a variety of circumstances and data should be used for comparison purposes.
