Dell Storage SC4020
Dell offers all-flash versions of its SC Series (Compellent) and PS Series (EqualLogic) storage arrays. In 2013, Dell redesigned its Storage Center operating system to be fully optimized for flash to support auto-tiering between read- and write-intensive drives to reduce the cost of all-flash storage. Dell's midtier SC4020 is an entry-level model that brings the cost of all-flash storage to only $25,000. It includes six 480-GB read-intensive SSDs for a total of 2.8 TB of raw capacity. Dell also introduced a flash-optimized multitier configuration that provides six 480-GB read-intensive SSDs and six 200-GB write-intensive SSDs for more than 4 TB of raw capacity with a $35,000 advertised street price.
