iNEMI Mass Data Storage Roadmap Ref: ASTC
iNEMI Mass Data Storage Roadmap • Sealed Helium Drive
iNEMI Mass Data Storage Roadmap • Shingled Recording • shipped by Seagate in 2013 • 25% increase in areal density • Could be combined with dual differential read head for 2-dimensional magnetic recording (TDMR)
iNEMI Mass Data Storage Roadmap • Heat Assisted Magnetic Recording (HAMR)
iNEMI Mass Data Storage Roadmap • Bit Patterned Media (BPM)
Mass Data Storage Chapter Status Optical
iNEMI Mass Data Storage Roadmap Summary • Solid State • Flash capacity growth expected to continue • MRAM continued progress expected • HDD • Current demand high • Impact of Industry Consolidation • Symbiotic relationship with SSD technology • Overall HDD demand helped by SSD applications • HDD vs Flash/SSD cost differences (~15-20X) not likely to change. • SSD shipped storage capacity ~5% of overall • A/D growth will continue beyond 1Tb/in2 • Technical enablers’ progress will be key
iNEMI Mass Data Storage Roadmap Summary • Tape • LTO 6 shipping, 2.5 TB/cartridge 1/2", backwards compatible to 2 generations. • Oracle/StorageTek T10000 8.5 TB/cartridge • Impact of LTFS • Growth/Merger of HDD’s into Archival Storage Systems • Recent Demonstration by Sony & IBM of 125 Gb/sqi in tape format • Optical • Primary use for distribution & some archival backup • Push into multi-disk archive cartridges • Some R/W market ( i.e. Sony MO minidisc )
