WD Gold Vs UltraStar

Admin2 comments Estimated Read Time: 2 Minutes

Before we jump into how a Gold drive is different from ( or similar to ) an Ultrastar, Here is the chronology in which Gold demised and rose back to life from the proverbial Phoenix Ash.

October 2015 :
HGST stops operating autonomously , almost 7 years after the WD acquisition
October 2018 :
WD announces to Channel the transition from Gold to Ultrastar. Gold is Marked End of life
September 2019 :
WD announces that Gold will be Brought Back.

The New WD gold is based on the Ultrastar platform so we essentially have 2 similar ( or rather exact) products from WD. Ultrastar is the Legendary HGST platform that WD acquired and is targeted towards the enterprise market and for projects , while Gold is targeted towards channel as a stocking product.

WDs Decision to bring Gold back signifies the power of color - the brilliant marketing that WD always had. Gold as a color had somehow become a de-facto for the industry to rely on , drawing from rhetoric like 'Gold Standard' , Ultrastar just didn't have the marketing power that Gold had, despite being an arguably better product. WD realized that their was still a segment of Gold user which didn't migrate to Ultrastar as they anticipated, or worse they probably shifted to another brand. The easiest way to bring these customers back was to bring Gold back into channel and that's what WD did.

Now since both Gold and Ultrastar are the same platform , same drive, same specifications ; most of the difference is in the Positioning of the drives itself. Both are with 5 years warranty, both with similar MTBF and reliability. Little bit of difference between the two are

WD UltraStar WD Gold
Available in SATA and SAS Available only in SATA
Available with Various Encryptions and Formats ( 512e, 4Kn, 512n...) Only Available in 1 standard configuration
Multiple Part numbers under 1 capacity Single Part number per Capacity
Each Major Firmware or Technology change triggers a new part number. For Example 10TB Helium and 10TB air have both different part numbers. Silent Roll : New Technology, new firmware will also remain under the same part number
Stocking product for the Channel Enterprise product for System Integrators and large Projects
5 Year Limited Warranty 5 Year Limited Warranty

Which one should I buy UltraStar or Gold

  • if you are after a SAS drive, you have only UltraStar. There are no SAS Drives in Gold
  • if you are after a drive with specific byte per sector , Again Ultrastar is the only choice.
  • If you are looking for a SATA drive , take either Gold of UltraStar, they are the same great drive under the hood and it will be eventually down to pricing and availability to help you make a decision.

They are almost the same, but may not be exactly the same, as the firmware may be different. The WD 10TB Gold part number WD102KRYZ is very rarely changed, so even 2 WD Golds under the same part number WD102KRYZ can have different firmwares. If you buy an Ultrastar and a Gold from the same year, you can assume that both have similar firmware and are therefore the same. In terms of hardware, they are the same.

Thank you. This was useful. So a Gold and Ultrastar 10TB are same thing.
