Micron Technology has started shipments of the industry’s first SSD built on revolutionary quad-level cell (QLC) NAND technology. This was unveiled at Micron’s 2018 Analyst and Investor Event, the Micron 5210 ION SSD provides 33 percent more bit density than triple-level cell (TLC) NAND, addressing segments previously serviced with hard disk drives, which when this trickles down should allow lower cost for higher capacity SSDs. The introduction of new QLC-based SSDs positions Micron as a leader (Samsung doesn’t have theirs ready yet) in providing higher capacity at lower costs to address the read-intensive yet performance-sensitive cloud storage needs of AI, big data, business intelligence, content delivery and database systems.

As workloads evolve to meet the ever-increasing demands for real-time data insights and analytics, data centers increasingly need the capacity, speed, reliability and steady state performance that enterprise flash storage provides. Micron QLC NAND – reaching densities of 1 terabit with its next-generation 64-layer 3D NAND structure – is optimized to meet these demands and make SATA SSD performance and capacity more approachable than ever before.
