Standard 3.5-inch silver hard drive with SAS connector

HGST

HGST Ultrastar He10 10TB 7200RPM SAS 12Gbps 256MB 3.5-inch internal hard drive

SKU CH-NNQ9-6Q9JH

Helium-sealed 10 TB drive with 7200 RPM SAS interface and 256 MB cache

  • 10 TB capacity in a standard 3.5-inch form factor
  • HelioSeal technology enables superior power efficiency per terabyte
  • SAS 12 Gbps interface supports fast data transfer rates
  • 7200 RPM spindle speed with 256 MB cache for responsive performance
  • 25 % more capacity compared to 8 TB drives

Enterprise helium hard drive

The HGST Ultrastar He10 is a 10TB 3.5-inch internal hard drive that uses helium sealing and PMR technology to deliver high capacity in a standard enterprise form factor. It spins at 7200RPM with a 256MB buffer and connects via a SAS 12Gbps interface for deployment in storage arrays and servers.

Suited for RAID arrays and bulk storage

This drive suits administrators building high-density RAID arrays, backup targets or nearline archives where the 12Gbps SAS link and helium efficiency reduce power per terabyte. It is not for laptops, small-form-factor enclosures or any system that cannot supply a SAS backplane and 3.5-inch drive bay.

SAS 12Gbps interface decides compatibility

The single specification that determines fit is the SAS 12Gbps host interface; the drive requires a controller or backplane that supports this protocol. Without a compatible SAS connection the unit cannot communicate with the host system.

Questions about this item

How do I install the 3.5-inch SAS 12Gbps drive and what step is often missed?

Mount the 3.5-inch drive in a compatible bay, connect the SAS 12Gbps data cable and power connector, then ensure the controller firmware recognises the 10TB capacity before formatting.

What maintenance or replacement will the helium-sealed 10TB drive need later?

The HelioSeal enclosure is hermetically sealed at the factory; no helium refill or internal service is possible, so the entire drive is replaced once its rated workload or MTBF limit is reached.

Which limit appears first on the 7200RPM 256MB cache drive during sustained writes?

The 12Gbps SAS interface bandwidth and the 7200RPM mechanical throughput set the ceiling; sustained transfers will saturate the interface before the 256MB cache fills.
