What is HDD-Native?
Engineered from the Physical Layer Up
SMR (Shingled Magnetic Recording)
A write model that trades random-write flexibility for higher density, requiring sequential patterns, zone awareness, and careful workload shaping.
Power Pin3 Technology
Low-level control over drive power behavior — enabling reset, disable, and recovery strategies critical for large-scale system stability.
Head Depopulation
Reducing active read/write heads to improve yield, power efficiency, and cost — with implications for performance and capacity planning.
Command Duration Limits (CDL)
Time-bounded command execution that prevents long-tail latency, enabling predictable performance and tighter control under load.
