WD Gold is Western Digital's enterprise nearline hard drive line sold at retail - the same HelioSeal platform the company sells to datacentres as Ultrastar DC HC, under a different part number and through a different channel. Across the 6 pairs we can match today, WD Gold is dearer on 5 of them. Every drive in the line is CMR, so it is safe for a parity array without checking model by model.

Workload rating is recorded per part number from Seagate's datasheet for that exact model, not blanketed across the line — two drives of the same capacity can differ because they are different generations. A dash means the figure is not stated for that listing. Recording technology comes from the manufacturer's published CMR/SMR list; a model absent from that list is shown as UNVERIFIED rather than guessed. Rows priced above 3× this line's in-stock median are flagged and excluded from the winner callout and from every median we compute.

Cheapest of each on the same capacity. A dash means we have no live listing on that track today, not that the drive does not exist.
WD Gold is Western Digital's enterprise-class nearline hard drive line, sold at retail and through the channel. Nearline means the drives are built for storage that is always powered and always available but not constantly seeking - archives, backup targets, media libraries, the bulk tier of a file server. They run at 7200 RPM class, they are rated for a published annual workload figure rather than a duty-cycle guess, and they carry a five-year limited warranty.
That description will sound familiar if you have read our Ultrastar hub, and it should. Ultrastar DC HC is the same company's enterprise nearline platform. Above roughly 8TB both lines are helium-sealed on Western Digital's HelioSeal platform. The headline specifications Western Digital publishes for matched capacities line up: same rotational class, same cache, same workload rating, same MTBF figure, same warranty term.
What differs is who the drive is sold to. Ultrastar is the line quoted to datacentre operators and OEMs by the pallet, under part numbers beginning WUH. WD Gold is the line stocked at retail under part numbers like WD181KRYZ, aimed at the systems integrator, the small business and the enthusiast who wants an enterprise drive without a purchase order. Two channels, two labels, one platform.
We say platform kinship rather than identity deliberately. Western Digital does not publish a model-to-model equivalence table, and we have not opened both drives. Firmware tuning and the support path attached to each label are not something we can verify from a product page, so we do not claim they match.
The table above is the reason this page exists. At every capacity where we can pair a live WD Gold listing against a live Ultrastar listing in the same condition, Gold is the more expensive side, and the gap is not small change.
Two things drive it, and they are worth separating because only one of them is about the badge.
The first is channel economics. Retail enterprise stock carries retail margin, retail return handling and retail warranty administration. Ultrastar reaches the same shelves largely through distributors serving a different customer, and the pricing reflects a market where the buyer negotiates volume. That premium is real but modest.
The second effect is much larger and is often mistaken for the first: the secondhand supply is overwhelmingly Ultrastar-branded. When a datacentre decommissions a fleet, the drives that flood the refurbished market wear WUH part numbers, because that is what was in the racks. There is no comparable stream of retired WD Gold drives, because WD Gold went into ones and twos into small servers that are still running. So the cheapest listing at a given capacity is frequently a decommissioned Ultrastar, and comparing it against a retail-new Gold overstates the badge premium enormously.
This is why our table compares new against new and refurbished against refurbished, never across. A blank cell means we have no live listing on that side in that condition, and we print a dash rather than reaching across the tracks to fill it. A comparison you cannot make honestly is better left visibly unmade.
There are good reasons to pay the premium, and we would rather name them than pretend the cheaper option always wins.
The warranty path is the strongest. A WD Gold drive bought new from an authorised retailer has a five-year limited warranty administered by Western Digital, and a clean proof of purchase. A decommissioned Ultrastar sold as refurbished carries whatever the reseller offers, typically measured in months, and the manufacturer warranty is usually long expired or void on a drive sold out of a fleet. If the drive is going somewhere that a warranty claim actually matters - a client site, a system you support commercially, anything where your time to replace it costs more than the drive - that difference is worth money.
Power-on hours are the second. A new Gold drive has none. A decommissioned Ultrastar may have four or five years of continuous spinning behind it, and the seller's grade is not a substitute for reading the SMART attributes yourself. Our recertified guide covers what the grades mean and which SMART values to check on arrival.
Availability is the third and least glamorous. Refurbished supply is lumpy. If you need eight matched drives at one capacity this week, the retail line will have them and the decommissioned market may not.
If none of those apply - if this is a home array, you are comfortable checking SMART data, and you are buying spares anyway - then the premium is buying you very little, and the numbers above say so.
WD Gold part numbers follow a readable pattern. The four or five digits after WD give the capacity in hundreds of gigabytes: WD8005FRYZ and WD8003FRYZ are 8TB, WD121KRYZ and WD122KRYZ are 12TB, WD181KRYZ is 18TB, WD202KRYZ is 20TB, WD221KRYZ is 22TB. The letter block distinguishes generations and cache sizes within a capacity rather than a different class of drive - WD121KRYZ and WD122KRYZ are both 12TB Gold, the later one carrying 512MB of cache against the earlier 256MB.
Every WD Gold drive is CMR. Western Digital has never shipped shingled recording in this line, which is the single most important thing to know if the drive is going into a parity array, and it is why WD Gold does not need the per-model recording-technology decoder that our BarraCuda and WD Red pages carry. If a listing claims to be WD Gold and the recording technology is described as SMR, the listing is wrong about something.
Our live table shows the capacities we currently have in stock, and it will have holes. Holes are a supply fact, not a catalogue gap we are hiding: as of the August 2026 seed we could not find a single live WD Gold 16TB listing, only Red Pro and Ultrastar at that capacity. We would rather show you nine capacities we can actually price than pad the table with a tenth we cannot.
The line also extends beyond spinning disks - Western Digital has used the Gold badge on enterprise NVMe SSDs. Those are a different product on a different technology and they are not in these tables, which cover the hard drive line only.
Every figure on this page is the cheapest live listing we hold for that drive at the moment you loaded it. Cost per terabyte is the price divided by the advertised capacity, which makes drives of different sizes directly comparable and is almost always the number that should decide the purchase.
New and refurbished are tracked entirely separately, everywhere on this site. A refurbished price is never scored against a new drive's history, never averaged into a new-drive figure, and never used to fill a blank on the new side of a comparison.
Multi-packs are excluded from these tables. A four-pack listed at a single-drive price would show a per-terabyte figure a quarter of the true one and would sit at the top of every ranking it touched, which is a defect we have had to repair before elsewhere in the catalogue.
Where a seller has put Renewed or Recertified in their own listing title, we file the drive as refurbished even when the marketplace reports it as new condition. Four of the listings in the August 2026 WD Gold and Exos seed were exactly that case. Taking the marketplace's word would have put refurbished prices on the new track and dragged the new-drive figures down by a third.
WD Gold deals scores every drive against its own price history on its own condition track · the Ultrastar hub is the other half of the comparison above · the recertified guide covers what a refurbished grade means and which SMART values to check before you keep a decommissioned drive · the CMR drive list covers the lines where recording technology does vary by model.
They are the same enterprise nearline platform from the same manufacturer, helium-sealed on HelioSeal at the high capacities, with matching published specifications at matched capacities - 7200 RPM class, the same cache and workload ratings, a five-year warranty on new stock. Western Digital sells Ultrastar to datacentre and OEM buyers under WUH part numbers and WD Gold at retail under WDxxxKRYZ part numbers. We stop short of calling them identical drives, because Western Digital publishes no model-to-model equivalence and firmware differences are not something we can verify from a product page.
Partly retail channel margin, but mostly supply. Decommissioned datacentre drives are almost all Ultrastar-branded, because that is what fills racks, so the cheap end of the Ultrastar market is a refurbished market with no WD Gold equivalent. Our table compares new against new and refurbished against refurbished for that reason - it isolates the badge premium from the secondhand supply effect. Both comparisons still favour Ultrastar at the capacities we can pair.
CMR, across the entire line. Western Digital has never shipped shingled recording under the Gold badge. That makes WD Gold safe for RAID and ZFS parity arrays without checking model by model, which is not true of the consumer WD Red or Seagate BarraCuda lines where recording technology varies by model.
Yes, and people do it constantly. Both are 7200 RPM class CMR SATA drives designed for multi-drive enclosures. Match capacities, because a parity array sizes itself to the smallest member, and be aware that mixing a new drive with a decommissioned one means the two have very different amounts of life behind them - which matters for when you expect to replace them, not for whether the array works.
The Gold badge at retail is a SATA line. Western Digital's SAS enterprise drives are sold as Ultrastar, under part numbers ending AL rather than ALE. If you are filling a SAS backplane, that is the line to look at - and check the interface column before you buy, because a SATA drive will physically fit a SAS backplane connector while a SAS drive will not work on a SATA-only controller.
They are read from our catalogue when you load the page, and the catalogue is refreshed every few hours. The timestamp above the tables is the last successful refresh of the WD Gold rows specifically, not the time you happened to arrive.
Each of these carries the same live pricing and, where the family mixes recording technologies or interfaces, the same per-model decoder.
