Dell’s Cost-effective Flash Storage with TLC 3D NAND technology


To match the data all-encompassing, the IT professionals are gushing towards cheap and one solution end storage. Dell has made a significant place in the storage system vertical.

To the best learning, Dell’s newly introduced new SC4020 all-in-one disk arrays have up to 24 times performance enhancement and offers a same price for capacity as 15K hard disk drives, and up to 90 terabytes of raw flash capacity per Dell Storage 2U array.

Eric Burgener, research director of storage systems at IDC  cited cost has been the single biggest stumbling block to flash adoption in the data centre and he thinks that Dell’s announcement of a lower dollar per gigabyte price point for all-flash configurations will enable the use of flash technology across an even greater variety of enterprise workloads.

With Dell’s Data Progression intelligent data placement technology and the release of Dell Storage Center 6.6 array software, the Dell Storage SC Series arrays will be optimised on “new Mainstream RI flash drives based on TLC 3D NAND” said Dell in a statement. The Mainstream RI arrays have “the industry’s lowest-cost per gigabyte, highest-density enterprise flash drives” Dell said and so “offer SSDs at approximately the same price per gigabyte as high-end 15K HDDs and with up to 24 times performance improvement, up to six times the density, lower latency and lower power consumption”.

Burgener further said “Dell’s announcement of flash drives built on TLC 3D NAND technology puts them in the storage density lead at 45TB per rack unit for flash-based arrays and drops the dollar per gigabyte cost of enterprise flash storage to roughly the same cost as 15K RPM HDDs.”

As per understanding, Dell’s new virtualised storage array architecture enables an inventive approach to intelligently leverage multiple flash types in the same array based on workload goals and usage patterns.
