Deskstar NAS 4TB 7200 RPM

The HGST Deskstar NAS is a 3.5-inch internal hard drive built for consumer and commercial desktop NAS systems. It spins at 7200 RPM with a 64MB cache and connects through a SATA 6.0Gb/s interface. The drive is sold new in retail packaging.

SATA 6.0Gb/s interface

The single specification that decides fit is the SATA 6.0Gb/s interface. Your NAS enclosure or motherboard must provide a standard SATA data and power connection. The 3.5-inch form factor with dimensions of 146.00mm length, 101.00mm width and 26.10mm height also determines physical compatibility.

Sustained multi-bay operation

A rotational vibration sensor helps maintain performance when several drives operate in the same chassis. The 1 million hours MTBF rating and seek times under 12ms support continuous workloads rather than brief bursts. Media transfer rates are up to 20% faster than 5400 RPM drives.

Questions about this item

What does the 7200 RPM speed mean for actual NAS performance?

The 7200 RPM spindle delivers media transfer rates up to 20% faster than 5400 RPM drives and seek times under 12ms, improving multi-user file access in a NAS.

What does the SATA 6.0Gb/s interface cap in practice?

The SATA 6.0Gb/s link limits the drive's maximum burst throughput to 6Gb/s; sustained rates stay within that ceiling.

Will this 3.5-inch drive fit my NAS bay?

The drive measures 146.00mm long, 101.00mm wide and 26.10mm high, matching the standard 3.5-inch form factor used in desktop NAS bays.
