Western Digital 0F38755 HGST 20TB Ultrastar DC HC560 SATA 6Gb s SE 3.5″ Internal Hard Drive

Overview :

The 20TB Ultrastar DC HC560 SATA 6Gb/s SE 3.5″ Internal Hard Drive, with OptiNAND technology capacity-enabling features, delivers an unbeaten large storage capacity in a nine-disk platform (2.2TB/platter) with CMR recording format. OptiNAND integrates an iNAND Universal Flash Storage (UFS) Embedded Flash Drive (EFD) with traditional spinning disk media, and incorporates innovative changes to the firmware algorithm and system-on-a-chip (SoC). OptiNAND is not a hybrid technology. The drive works smarter, with enhanced firmware algorithms taking advantage of expanded metadata that has been offloaded to the iNAND, enabling more tracks per inch (TPI) with resulting increased areal density.
