Dell is launching a new flash drive storage array for the enterprises, equipped with SSDs based on Triple Level Cell (TLC) 3D NAND technology. The Dell Storage SC Series array models (Dell Storage SC4020 and Dell Storage SCv2000) can offer a storage density of up to 45TB per rack unit, roughly the same cost as 15K RPM HDDs.

Dell’s virtualized storage array architecture enables the intelligent usage of multiple flash types in the same array based on workload goals and usage patterns. With the release of Dell Storage Center 6.6 array software, the new Dell Storage SC Series arrays can adopt and optimize new Mainstream RI flash drives based on TLC 3D NAND.

The Dell Storage SC4020 can provide a complete 90 terabyte array in 2U of rack space. Additionally, Dell Storage SC8000 arrays can support 62 percent more flash for a total of up to 3 petabytes of raw flash capacity in a single array.

The Dell Storage SC Series arrays will begin supporting Mainstream Read-Intensive flash drives, based on TLC 3D NAND technology, in August 2015.
