Enterprise storage drives continued to push the limits of performance and capacity in 2020, with fast new PCIe Gen 4 SSDs at 30 TB and energy-assisted HDDs at 20 TB

"High-performance PCIe 4.0 SSDs are soaring past 30 TB," notes Carol Sliwa in SearchStorage, "and spinning hard drives are hitting 20 TB for a cheaper alternative to cope with the escalating growth of data as 2020 draws to a close.

Chip manufacturers also continued to push the envelope with denser 3D NAND flash that can help users lower the cost per bit and reduce their storage footprints. Micron unveiled its 176-layer 3D NAND in November at the Flash Memory Summit, although it disclosed no timeline for availability. In December, SK Hynix announced that it provided controller companies with samples of its 176-layer, 512 Gigabit triple-level cell (TLC) flash, which it calls '4D NAND' ..."
