Crafting a Sustainable Datasphere: Storage Innovation
summary
Seagate announces shipping-ready HAMR 30+ TB drives that double aerial density and aim to raise per-drive throughput (multi-actuation) while keeping power growth under ~25%. An NVMe HDD engineering sample and composable stack using NVMe/CXL/Redfish/CSI support disaggregated provisioning. System demos deliver ~13–26 GB/s from 48-drive enclosures. Linux VDO kernel changes deliver the same 4x data reduction but reshape layout, yielding ~18x sequential write and 86x random write improvement and ~1.5x read speed increases.
