HGST Deskstar NAS 7200rpm 128MB 3.5" SATA internal hard drive

SKU CH-1BD8-NV163

A 3.5-inch SATA hard drive engineered for desktop NAS systems with 7200 RPM speed and 128 MB cache

  • Optimised for NAS with 7200 RPM speed
  • 20% faster transfers versus 5400 RPM drives
  • 128 MB cache boosts data access
  • Rotational vibration sensor protects multi-drive arrays
  • Up to 10 TB capacity for large storage

Capacity and interface

This HGST Deskstar is a 3.5-inch SATA internal hard drive built for desktop NAS systems. It operates at 7200 RPM with a 128 MB cache and a 6 Gb/s SATA interface. The drive supports capacities up to 10 TB and uses Advanced Format technology.

Suited for multi-bay NAS.

It suits users building or expanding consumer and commercial NAS arrays, external storage enclosures, PC gaming libraries or video editing storage where rotational vibration sensors help reliability in multi-drive RAID setups. It is not for buyers who need a 2.5-inch form factor for laptops or portable devices, nor for systems that lack a 3.5-inch bay and SATA power and data connections.

7200 RPM spindle speed

The 7200 RPM spindle speed delivers a 20 percent faster transfer rate than 5400 RPM drives with a seek time under 12 ms. This single specification decides whether the drive meets the performance threshold for your NAS workload versus lower-speed alternatives.

Questions about this item

How do I install the 3.5" SATA drive into my NAS and which step is often missed?

Mount the drive in a 3.5-inch bay, connect the SATA data and power cables, then enable the drive in the NAS RAID manager; the step most users skip is adding the new disk to the array or storage pool.

What maintenance or replacement will the 7200 RPM Deskstar NAS drive need over time?

No scheduled maintenance is required; monitor SMART health and replace the drive if reallocated sectors appear or after the manufacturer-rated workload limit is reached.

What limit appears first on the 128 MB cache drive during sustained multi-drive RAID use?

The rotational vibration sensor keeps performance stable, so the first bottleneck is usually the 6 Gb/s SATA interface bandwidth rather than the drive itself.
