Integrated RV sensors

Multiple sensors detect the slightest shock and built­in RV sensors also compensate for rotational vibration

- eliminating the possibility of ‘knock-on’ vibration in
multi-bay NAS configurations system.

Reliable ‘always-on’ operation

Today’s NAS drives must deliver high data transfer rates
and simultaneous upload and download 24-hours x
7-days. Offering high reliability and scalability, N300
drives achieve max. 180 TB/year workload factor.
