Today we have a pair of Western Digital / HGST Ultrastar DC HC510 10TB hard drives for review. Our two test drives are helium-filled 10TB drives which may be something our readers look to for higher-performance 10TB drives. The HGST WD Ultrastar DC HC510 10TB Hard Drives are enterprise class drives that utilize HGST’s PMR and HelioSeal technology and designed for reliability. In our review, we are going to take a look at how these drives perform.
Our drives are from the transition period where WD was phasing out the HGST brand and instead of using the Western Digital brand on the HC510 series. As a result, you can see we have a Western Digital label and some HGST SMART data. Since HGST was purchased by WD several years ago, you should read those two interchangeably.
HGST WD Ultrastar DC HC510 10TB Hard Drive Overview
HGST was not known for colorful labels on the HDD’s they manufactured and in the can of the HGST WD Ultrastar DC HC510 10TB Hard Drives we have today we see a simple white label with black text.
Here is the flip side of the drive.
Flipping the hard drive over we see the PCB on the back. We can also see the SATA connector. There are two variants, a 12Gb/s SAS3 version of the drives we can see as very popular in the server space. The 6.0Gb/s SATA III drives here are more suited for NAS devices and servers without SAS3 controllers. Although SAS3 is generally considered to be the better interface, if you have a NAS device, or if you want lower power consumption and cost, SATA is still very popular.
These days, 3.5″ hard drives are generally designed to sit in some sort of network attached storage. In the data center, and in edge NAS devices, that can range from dedicated storage nodes to in-compute node storage. As SSDs continue to take share, larger drives are important, as is the ability of those drives to run cool and reliably. SSDs generally enjoy faster speeds, higher density per rack unit, and better reliability. These days hard drives need to have a high capacity which is why we are starting this new series of hard drives for NAS applications.
Let’s take a quick look at the HGST WD Ultrastar DC HC510 10TB Hard Drives specifications before moving on to testing.
