Other HDDs may operate in an idle mode, which is a power-saving state that permits the HDDs to quickly change-over to the active mode, when needed. In storage racks containing numerous HDDs, a majority of the HDDs may be operated at idle mode for a majority of the time. Where a large number of HDDs are operated at idle mode, a fixed common idle speed shared by the numerous HDDs can cause unwanted excitation, vibration, and resonance. This can yield increased wear on rack components, decreased performance from the HDDs therein, and increased noise. Variable HDD idle spindle speeds mitigate the foregoing, which is caused by an idle spindle speed previously common to many, if not all HDDs within the data storage rack."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Variable hard disc drive idle spindle speeds within a disc array","description":"A data storage rack may only have a subset of the HDDs therein operating in an active mode where read/write operations may be performed.
