22TB WD Red Pro, WD Gold and WD Purple Hard Drive Released

19 juillet 2022 à 16:00

Western Digital Release 22TB Hard Drive in WD Red Pro, WD Gold and WD Purple

That’s Right! WD has now officially released their 22TB series of HDDs to the WD Gold, WD Red Pro and WD Purple Pro series of hard disks. So, why is this such a big deal? Well, anyone who has been watching the development of hard drives over at Western Digital will have surely noticed a tremendous change in strategy by one of (if not THE) biggest brand in hard drives in the last couple of years. For a long time, WD had been a little more cautious in it’s releasing of larger capacities (especially compared with their biggest rival Seagate) and was rarely the first to commercially release the biggest capacities into the consumer and business market. However, the last 24 months have seen WD change this development/release method dramatically and we have seen them release a wide variety of extremely high capacity HDDs into their respect ranges (we only JUST reviewed their 20TB WD Red Pro on YouTube and Western Digital Ultrastar HC560 20TB HDDs here on NASCompares shortly after release). Add to this that these larger capacity HDDs are getting added to each of the brand’s highest-profile product ranges (as well as the 26TB Ultrastar UltraSMR drives being released now in July ’22) and we are seeing a very, VERY different WD to one we saw back in 2019/2020. So, let’s take a closer look at these three new 22TB Hard Drives, what they are designed for and what separates them from one another!

Hardware Specifications of the WD Red Pro, WD Purple and WD Gold 22TB Hard Drives

The first thing to note is that these three 22TB hard drives is that they are designed very similarity in terms of standard hardware architecture. They are all 7200 RPM (rotations per min) and data is spread across 10 internal platters that are comprised of 2.2TB per platter. Despite it’s remarkable capacity, the drive uses traditional CMR/PMR, but is improved upon with the use of energy-assisted magnetic recording too. These amply internal physical storage spacing in accompanied with a huge 512MB of on board cache to keep things moving and each drive also features a small flash module on board known as OptiNAND (we will go into more detail on that in a moment). All three 2TB Hard drives are available in SATA/6Gb (and SAS options available in other model IDs), but thanks to small differences in the gearing of each drive to be better suited to their end user, the WD Red Pro and WD Purple Pro have a maximum reported 265MB/s Sustained Sequential Read and the WD Gold has a much higher and possibly industry winning (for SATA in traditional platter-arm design) 291MB/s Performance, almost half way saturating SATA 6Gb/s. Herre is a breakdown of the specifications of each of the WD 22TB Hard Disks:

What is the Difference Between the 22TB WD Red Pro vs WD Gold vs WD Purple Pro HDD?

The WD Red Pro series of HDDs are designed for use in 24×7 NAS servers that are used in Medium-large businesses (recommended for any system in desktop or rackmount above 8 bays). The WD Gold series is designed for Enterprise, Data Center and/or Hyper-scale deployment, as they are geared towards a much faster spin up and spin down, whilst also ensuring high sustained speeds over time and can endure larger scales of write-delete-re-write throughout their lifespan (something very common in enterprise hot-warm-cold storage systems that use different media types at each tier). Finally, there is the WD Purple Por series, a range of drives specifically geared towards surveillance (cameras and data recording instruments generally) and although similar in deployment to the WD Red Pro series (ie small-medium-large business and above 8 bays of storage per system), the main difference is that WD Purple is significant;y geared more towards Write than read, as NVR/Surveillance-servers will spend 95%+ of there operations time WRITING data from recording cameras etc , whilst 5% or less will be spent retrieving/viewing those recordings.

The main difference between all three in terms of actual use is:

  • The WD Purple 22TB is an HDD that will allow a tremendously sustainable Write Speed over time but not at the expense of durability, thanks to a high 2.5M MTBF and 550TB annual workload. Therefore ensuring that surveillance recordings are consistent and the drive will have sufficient robust hardware to endure repeated write actions over and over. That heavier focus on write-over-read results in the drive arriving noticeably lower in price than the WD Red Pro or WD Gold.
  • The WD Red Pro 22TB HDD on the other hand has a much better Read/Write balance and although is not quite as high in it’s durability upon repeated/recycled writing, it makes up for it by being much better than the Purple Pro when it comes to mixed and sporadic access patterns, as a 24×7 large scale NAS server is likely to do
  • The WD Gold 22TB is the premium Hard Drive of the three, with it’s excellent sustained read AND write, as well as high durability of 550TB per year workload, 2.5M MTBF hours and it’s suitability of deployment in hyperscale (12-24-48+ bay) rack environments of NAS or SAN. The only real downside compared with WD Red Pro and WD Purple Pro is that the drive is noisier and consumes more power in use to maintain those speeds and durability over time. The price tag of the WD Gold (at least at the time of writing) is higher than the WD Red Pro and WD Purple Pro too – though that can change later as larger capacities arrive and the RRP becomes increasingly flexible.

That is the core difference between all three 22TB HDDs that WD have released. But what about OptiNAND? Why is that a big deal?

What is OptiNAND and Why is it so Important on a big drive like the WD 22TB?

Of course, users who have been following the developments of WD in their roadmaps and reveals of larger-scale drive media will be aware that the WD Red Pro, Purple and Gold 22TB also features a new technological design being rolled out in these bigger drives to merge existing storage technologies into something even better – OptiNAND. This is a new approach to an old idea that never really took off, where the benefits of small areas of faster NAND storage (more typically associated with SSD media) and affords a small area of NAND to a larger scale hard drive to be used for metadata and for storing data in the event of power failure. Flash is also interesting from a persistence standpoint. DRAM gets flushed on power loss, but NAND is non-volatile and can continue to keep metadata information without having to re-hydrate after a boot sequence, be removed from the system for some reason, or any other event where power drops. The newer gen 18, 20 and 22TB hard drives arrives with a portion of 64-layer/64GB BICS3 (3D TLC)

WD states that OptiNAND drives can secure more than 100MB of write cache data in the event of an unplanned power loss, a 50X improvement over standard drives that can flush about 2MB. Hybrid Drive media is not new, but whereas older generation hybrid drives were more parallel in architecture, this is far more intertwined. It also brings enhancements to the firmware algorithm and system-on-a-chip (SoC). Once again, to be clear, OptiNAND and its iNAND isn’t flash cache (such as the 512MB this drive also features). Rather, it’s a portion of flash memory used to store metadata–or data about existing data–so they can be managed more efficiently.

The slice of iNAND has its own dedicated controller, much like an SSD. While metadata management itself doesn’t help to increase platter density, it enables a range of benefits that do. As one can imagine, the higher the density of the HDD, the more metadata it generates. Moving metadata to a fast, dense and scalable storage area gives more freedom for manufacturers to create higher capacity drives.

OptiNAND DRAM

But why choose NAND over DRAM? Western Digital explained back in August 2021 that modern high-density HDDs generate gigabytes of metadata and it’s too costly to include sufficient  DRAM to hold it. In addition, moving metadata to their own dedicated area will free up more space on the platters themselves to store user data. There’s more to it than capacity increases, though; using OptiNAND also helps with reliability, specifically with the repeatable runout (RRO) and adjacent track interference (ATI).

Overall, what we find in the WD Ultrastar HC560 20TB hard drive architecture is a solidly designed and hugely impressive piece of hardware that challenges alot of the standard conventions of hard drive storage (in AND outside of server use).

When Will the WD Red Pro, WD Gold and WD Purple Pro 22TB Hard Drive Be Released and the Price?

In short, all three 22TB Hard Drives are available NOW, as they were officially released by Western Digital Earlier today. Expect stock to take a little longer to arrive, maybe by the end of July ’22, but as we speak, they are being gradually added to WDD’s websites and online portals. Regarding pricing, only the WD Red Pro Price of £601 from WD themselves. The rest of the pricing of 22TB drives in WD Gold and Purple will likely hit circulation shortly.

WD Red Pro vs Seagate Ironwolf Pro vs Synology HAT5300 Hard Drives – Which Should You Buy in 2022/2023?

6 juillet 2022 à 01:02

Seagate Ironwolf or WD Red or Synology HAT5300 HDDs – Best for your NAS?

Choosing the right hard drive media to go inside your Network Attached Storage (NAS) server can be a lot more complicated than you might think. A long time ago (about 20 years at least) buying hard drives was much easier, as the technology was significantly less evolved. The difference between one hard drive and another could be the capacity, physical, size or the interface – that is about it! But much like any other kind of technology, over time hardware designers were able to improve it, make it more efficient, increase the storage, speed up the access and all the while sticking with the same 3.5″ physical scale. The result of all this development was that tailored/designed drives arrived that were geared internally towards specific tasks (thereby allowing designers to focus the HDDs development towards one specialization more than others). Fast forward to 2022/2023 and you find that the HDD market is considerably more diverse and brands have much more layered portfolios of drives and one big, BIG area of hard disk development was with NAS/Server HDD media. These are drives that are designed to be on 24×7, be prepared to spin up very quickly with little notice, be better suited to being deployed in larger quantities together (i.e RAID configurations made up of many drives) and all the while combating vibration and increased temperatures to maintain a healthy and stable level of use at all times. Today I want to look at three hard drives that are designed for large-scale NAS deployment (such as 8-24-bay rackmount and 8-12+ bays desktop NAS systems), as all three are the current popular choice for this kind of NAS system. There are the long-established HDD vendor drives, the WD Red Pro series and Seagate Ironwolf Pro range, and there is the NAS-brand labelled Synology HAT5300 series (built on Toshiba MG06/06/08 Enterprise series, but with Synology firmware in services included). With a new generation of NAS Hardware arriving from Synology in 2022/2023, as well as a change in support and compatibility listings by the brand in several of their releases, now is a very good time to take a look at how these three NAS HDDs compare in design, utility, performance and value. With WD and Seagate having a considerable amount of history in their Red Pro and Ironwolf Pro ranges respectively in the NAS industry, many users are still unsure about the Synology HAT5300 and whether they should make the switch, design its shift in architecture towards a more enterprise build (arguable closer to Ultrastar and Seagate EXOs, than Red or Ironwolf). Let’s take a closer look at these three drives and hopefully help you decide which one deserves your data!

WD Red Pro vs Seagate Ironwolf Pro vs Synology HAT5300 – Capacity

Let’s be honest, next to ‘price’, the overall capacity of a hard drive is going to be of importance to the majority of NAS buyers. Yes, you can take advantage of RAID and multi-bay NAS systems in order to bolster the available capacity available to you (as well as the redundancy and performance of course), but you are still going to need to factor in the capacity on offer. The Synology HAT5300, WD Red Pro and Seagate Ironwolf Pro series all arrive in multiple capacity versions (with prices scaling appropriately of course) and you will find that as the drives increase in capacity, their internal hardware and design get decidedly beefier. That said, it would be remiss not to highlight that Synology and their HAT5300 (and HAS5300 SAS drives, which we will not really factor in this comparison) have not been in the market as long as WD/Seagate and although they have made a solid start in presenting a portfolio of HDD and SSD drives, the range of capacities on offer from the HA5300 range is pretty sparse. Just to give you a little perspective on this, here is how the three HDDs compare in available drives on offer:

14TB  ✔ ✔
16TB ✔  ✔ ✔
18TB  ✔ ✔
20TB  ✔ ✔
22TB  ✔ (Revealed but release TBC) ✔ (Revealed but release TBC)

As you can see, the WD Red Pro and Seagate Ironwolf Pro drives current provide 10 different capacities from 2TB to 20TB for PRO NAS deployment (with the 22TB versions of their respective ranges announced and arriving soon). This does not include the non-pro versions of these series (won’t touch on these further, but worth highlighting) and with that, a NAS Buyer can scale their budget quite well across multiple bays and their budget. For example, a user could opt for 4x 10TBs in a RAID 5 and get 30TB of usable space, or instead opt for 8x 6TB drives in a RAID 6 and get 36TB – this allows a buyer to spend more of their budget towards the NAS hardware than the drive media, or visa-versa. Now, Synology only currently provide 4 different capacities (with the 4TB drive being added in mid-2022) and although it makes sense that the brand would want to develop in this area in a wave-by-wave release strategy (continuing to invest and develop as the series is embraced), for many the lack of smaller capacities AND the lack of the 18TB and 20TB tier is a little problematic. Toshiba recently unveiled their MG09 18TB Enterprise HDD and in a recent roadmap reveal, plans for 20TB and 22TB HDDs in the next 12 months, but right now it is impossible to ignore that in terms of available capacities, the WD Red Pro and Seagate Ironwolf Pro and considerably more fleshed out in their respective ranges.

WD Red Pro vs Seagate Ironwolf Pro vs Synology HAT5300 – Price

Alongside capacity, the price tag that the Synology HAT5300, WD Red Pro and Seagate Ironwolf Pro hard drives arrive with is going to be a big continuing factor on which one populates your large-scale NAS server. Although all three brands have their RRPs stated on their respective product pages, there have been several factors in the last 12-24 months (the pandemic, the rise and decline of chia crypto, semiconductor shortages, droughts in Taiwan, trade wars, actual wars and more) than have led to supply levels of large scale HDDs to be significantly reduced. Unsurprisingly, this has resulted in the price points for these hard disks to significantly increase (often a noticeable degree above the original RRP). As each HDD capacity in the WD, Seagate and Synology series’ have their own price based on the internal hardware to support that much data, comparing their price is a little tricky. Additionally, prices and availability differ quite wildly between countries, as stock levels and the ease of the supply chain are being affected differently by the factors mentioned earlier related to shortages. So, below I have listed the prices of each brand’s drives. Note – these prices are calculated at how much per Terabyte (TB) and in order to keep it fair, I have picked the newest/largest drive from each brand as the price average (as smaller drives have a typically less accurate series-wide price per TB overall). I picked Newegg, SCAN and Amazon.de for the prices, as they had pricing AND stock of all drive capacities on all brands in stock at the time of writing for each region and therefore gave a more accurate market pricing for comparison (14/06/22 – date of writing):

Region / eShop Synology HAT5300

WD Red Pro

Seagate Ironwolf Pro

Newegg (US) – avg price per TB $39 per TB $26 per TB $25.45 per TB
SCAN (UK) – avg price per TB £38 per TB £31.90 per TB £27.20 per TB
Amazon (DE) – avg price per TB €46.81 per TB €38.90 per TB €31.45 per TB

The price of the Seagate Ironwolf Pro series is noticeably lower than both the WD Red Pro and Synology HAT5300 (especially in Germany and other parts of Europe) and although these prices are an average based on the largest current available drive from each brand, if you look at the lower capacities you will find that this average price per TB is still pretty accurate throughout. The WD Red Pro is reasonably proved and on offer periodically (not quite as often as the Seagate admittedly) and in the US is much more competitively priced. The Synology HAT5300 series however is consistently the highest price of the three. Now, it needs to be factored in that the design and durability of the HAT5300 (as mentioned earlier) are much more comparable to that of the Seagate EXOs and WD Ultrastar series of HDDs for data centers, which no doubt affects the price. Equally, unlike Seagate and WD who produce their HDDs internally, the Synology HAT5300 is built on Toshiba MG06/MG07/MG08 and no doubt that results in Synology having to factor in an additional profit margin into their production and sale. We WILL be shortly discussing how this more enterprise design AND the Synology NAS universal selling points benefit this drive over the WD Red Pro and Seagate Ironwolf Pro drives, but when it comes to price point, it definitely goes Seagate 1st, WD 2nd and Synology in 3rd.

WD Red Pro vs Seagate Ironwolf Pro vs Synology HAT5300 – Hardware

As mentioned in the introduction, NAS hard drives are the result of HDD development improving over the years and then splintering into multiple specialised storage deployments (eg surveillance needing heavy write, cold storage needing endurance, laptops needing low power use and NAS servers needing 24×7 use). The Synology HAT5300, WD Red Pro and Seagate Ironwolf Pro drives are all very, VERY much designed with heavy-duty NAS deployment in mind and although you CAN use them in smaller systems and even desktop PCs, it would be a tremendous waste of their utility and design (like using a chainsaw to cut a slice of bread). Now all three branded drives have specialised internal hardware/firmware that maintains the drive in particularly vigorous and large-scale deployments (all the way up to 24 bays and higher), so I won’t really be giving any one brand an advantage for vibration, temperature, balance or spin up/spin down utility – all three of the Synology HAT5300, WD Red Pro and Seagate Ironwolf Pro have their own specialized components inside for this that it would be extremely difficult to compare one way or another here. The fact they have them is good enough for me. However, this is certainly going to be where the more enterprise design of the HAT5300 will stand out against the Pro design of the WD Red and Seagate Ironwolf:

MTBF (hours) M=Million 2.5M 1M 1.2M
Warranty 5years 5years 5years

Now, the officially reported transfer speed of each drive is not something we are going to dwell on. 1) the difference is tiny, 2) different scale/power/RAID configs will result in varied transfer rates and 3) I have personally tested all three and even in sustained Read/Write activity, they ALL hit 260-207MB/s consistently. However, we DO need to discuss durability and on-board caching. The Synology HAT5300 arrives with a SIGNIFICANT increase in its durability rating, with almost DOUBLE the annual workload rating (eg how many Terabytes the drive can have written and re-written per year) compared with the Seagate and WD HDDs. This also means that the drive has a significantly higher mean time between failure (i.e expected failure rate between deployment>drive-dies>replacement) at more than double. Now, although a lot of durability and sustained use is why Synology seemingly opted for the Toshiba MG series as the base for their branded drive series, but the drive also has Synology specialised firmware onboard. This results in two key benefits to Synology NAS users. The first is that the drive can have it’s specific spin, cache, access and load cycles tailed to Synology NAS system operations, whereas Seagate and WD have to be a little more open in their firmware to suit ‘all’ NAS servers. Pretty much all modern NAS drives run on one form of Linux or another (as well as TrueNAS of course, let’s not overlook FreeBSD etc) but this more precise firmware gearing in the HAT5300 means it will likely always be the most efficient drive for Synology NAS of the bunch. The other benefit of the HAT5300 in Synology NAS deployment is that the drive’s onboard firmware can be updated via the Synology DSM user interface and storage manager (without powering the device down), whereas the WD and Seagate HDDs require you to remove drives individually from the system (and RAID Pool of course if already in use) and update the firmware via a PC/Docking station. Although HDD firmware updates are much, much less frequent than many other types of technology and typically very small improvements, this is still something that the more data storage savvy user will want to stay on top of.

The Seagate and WD Drives on the other hand are considerably similar, with both drives having 7200RPM, 300TB annual workload and quite comparable MTBF. However, the WD Red Pro drive pulls ahead thanks to its 512MB of memory on the largest capacities and (more importantly) its inclusion of WD’s new OptiNAND technology. This is a recently developed HDD design choice (being included in their larger tiers currently and likely continuing into the 22TB+ tier) where alongside the nine platters of storage, the drive also features a small area of flash storage on board that is designed to store metadata and other indexing data using by the connected client system. Not to be confused with hybrid drives (optical drives that featured a decent-sized chunk of SSD space for the likes of an OS for large-scale caching), OptiNAND means that important table and micro-associated data that the drive needs to consult when the bulk of the platter houses data is accessed is accessible much, much more quickly and when drives are getting to this large scale of 18-20TB of storage, these increases can make a small but important difference. The Seagate Ironwolf Pro SSD is still an excellent drive, but leases out to WD and Synology’s branded drive, as the other drives have a largely better hardware offering included.

WD Red Pro vs Seagate Ironwolf Pro vs Synology HAT5300 – Noise

If you have EVER worked with larger-scale HDDs and enterprise-grade drive media (not just these three HDDs, but the EXOS, Ultrastar and Gold series too), then you will know that these drives can be particularly noisy. This noise stems from the larger drive needing more horsepower under the bonnet to hit that expected Read/Write performance levels sporadically – something that is particularly important when it comes to large population NAS/Server use being 24×7. The result is that these Pro and Enterprise drives will vibrate more than most, hum loudly when in operation and continuously click with the rapid movement of the arm/actuator inside as it has to rapidly access a large number of internal platters. We have discussed this at length on NASCompares previously over on YouTube and you can check out examples embedded below of noise testing that was performed on all three HDDs (you can open them in a separate TAB if you click the title or watch in the browser:

Synology HAT5300 Noise Test WD Red Pro Nosie Testing Seagate Ironwolf Pro Noise Testing

Now, the impact of noise in your home or business NAS environment is tremendously subjective. As these three drives are all too often designed for deployment in 8-12 bay desktops and 16-24 bay rackmounts (both largely metal chassis), the result is that in most cases you will NOT be able to hear the NAS HDD, as it will be drowned out by the noise of the multiple high RPM fans on the NAS or their impact on the metal chassis. However, if you plan on deploying these Pro/Enterprise drives in systems with LESS than 8-Bays and plan on being in the same room as the system, then you will DEFINITELY hear them. In order to test these drives, I took a large-scale, 9-platter version of the Synology HAT5300, WD Red Pro and Seagate Ironwolf Pro, then installed them in a modest 4-Bay NAS (as this would largely eliminate the fan noise and multiplying factor of a metal chassis) and instead opted for the largely plastic DS920+ NAS. The noise level was recorded using a phone+microphone 20cm from the DS920+ The drives were recorded during a ‘Benchmark Test’ selected in the DSM 7.1 Storage Manager, over 25-30 seconds, Below were the results:

Synology HAT5300

WD Red Pro

Seagate Ironwolf Pro

As you can see, the difference between them was very, very small and the Seagate and Synology were similarly noisy (though even then at this db(A) range, this is still very small. Overall, I don’t think you can choose between the Synology HAT5300, Seagate Ironwolf Pro or WD Red Pro in terms of noise, as they are all ultimately very noisy drives when in single/RAID deployment regardless.

WD Red Pro vs Seagate Ironwolf Pro vs Synology HAT5300 – Verdict

Overall, the Synology HAT5300 is still the most enduring hard drive here (thanks to that enterprise tier design) and the one that will likely be the most useful in a Synology enterprise NAS drive deployment (factoring in that firmware, ease of update and potential for bundle deals). However, it is still a much, MUCH more expensive drive that is available in fewer capacities and still only hits 16TB at the time of recording. In terms of getting the job DONE, the WD Red might not be the lowest price, but with its onboard flash in the larger capacities, a larger amount of onboard cache, fastest reported warranty turnaround and larger variety of smaller capacities that cover both Pro and normal, the WD Red Pro is the middle ground choice that ticks all the boxes and will be the one you know will shut up and do the job! The Seagate Ironwolf is by FAR the best value for money, with the best price point in and out of special offers, as well as inclusive three YEARS of data recovery services thrown in, Health management software onboard and almost always releasing the biggest capacity drives first (and at the best price) – the Seagate Ironwolf Series is the most accessible and storage services choice in 2022.

WD Red Pro 20TB NAS Hard Drive Released

1 mars 2022 à 01:00

WD Red 20TB NAS Hard Drives Now Available


Good news for anyone looking at buying a new NAS system and wanting to max out their storage on day one, or users looking up increasing their existing storage, with the release of the new WD Red Pro 20TB NAS Hard Drive. Arriving with the same level of robust and high workloads of the previous Red Pro HDDs, this new 20 Terabyte model arrives with NAS specific engineering and larger scale rackmount servers in mind. As this is a new, professional series hard drive at the 20TB capacity level, you can fully expect the WD Red Pro WD201KFGX to cost a pretty penny! So, let’s discuss the hardware of the new hard drive and see if it should be your next storage purchase in 2022?

WD Red 20TB WD201KFGX Full Hardware Specifications


The hardware inside the WD Red Pro 20TB WD201KFGX is centred around heavy-duty storage use, in a 24×7 server environment. Although arriving at a slight pinch lower in workload and durability than WD Gold or Ultrastar drives, this 20TB is still going to result in some solid performance that only data-center/hyper scale users are ever really going to exceed. Let’s go through the hardware specifications


  • Model ID – WD201KFGX
  • Storage Capacity – 20TB
  • Interface – SATA
  • Recording Technology – Conventional Magnetic Recording (CMR)
  • Form Factor – 3.5″
  • RPM – 7200
  • On-board Cache – 512MB
  • Transfer Speed – 268MB/s Reported Maximum
  • Load/Unload Cycles – 600K
  • Annual Workload Rating – 300TB
  • Active Power Use – 6.9W
  • Idle Power Use – 3.8W
  • Standby/Sleep Power Use –  1.6W
  • Warranty – 5 Years
Although the performance of the new WD Red Pro 20TB is a pinch lower than the 18TB (272MB/s vs 268MB/s), this is still a very small differences and the 20TB WD201KFGX is still higher in sequential Read/Write than the rest of the WD Red and WD Red Pro series.

What WD Say the New Red Pro 20TB WD201KFGX Features


Western Digital have always been remarkably proud of their WD Red NAS series of hard drive (and SSD in recent years) Media.   The WD Red Pro 20TB is no exception and they detail exactly what sets it apart from other Pro and Non-Pro class media.



Control Rapid Data Growth – Engineered specifically for NAS systems with up to 24 bays, WD Red™ Pro hard drives are optimized for multi-user NAS environments and are designed to handle high-intensity workloads in 24×7 environments. WD Red™ Pro is ideal for protecting, archiving, and sharing rapidly growing data with many users or multiple data-hungry applications.


Exclusive NASware™ 3.0 Technology – Our exclusive advanced firmware technology, NASware™ 3.0, enables seamless integration, robust data protection, and optimal performance for NAS systems operating under heavy demand. Built into every WD Red™ Pro hard drive, NASware™3.0’s advanced technology improves storage performance by increasing compatibility, integration, upgradeability, and reliability.


Built for Optimum NAS Compatibility – WD Red™ Pro drives with NASware™ technology take the guesswork out of selecting a drive. Optimized for NAS systems, our unique algorithm balances performance and reliability in NAS and RAID environments. Simply put, a WD Red™ Pro drive is one of the most compatible drives available for NAS enclosures. But don’t take our word for it. WD Red™ Pro drives are a reflection of extensive NAS partner technology engagement and compatibility-testing.


Larger NAS Bay Shock Protection – WD Red™ Pro drives are equipped with a multi-axis shock sensor that automatically detects subtle shock events and dynamic fly height technology which adjusts each read/write function to compensate and protect the data. This combination of technology further protects the drives in larger NAS systems with up to 24 bays and helps increase hard drive reliability.


3D Active Balance Plus – Our enhanced dual-plane balance control technology significantly improves the overall drive performance and reliability. Hard drives that are not properly balanced may cause excessive vibration and noise in a multi-drive system, reduce the hard drive life span, and degrade the performance over time.


Error Recovery Prevention – Built specifically for RAID and NAS environments, WD Red™ Pro drives come equipped with error recovery controls as part of NASware™ 3.0 technology to help reduce drive fallout in RAID applications.


Western Digital has been using OptiNAND technology to increase the capacity of new drives. To support OptiNAND, the WD Red Pro 20TB comes with an iNAND UFS flash drive (EFD). There has been no formal confirmation of the NAND memory capacity of the disk. According to Heise Medien, a German news site, a Western Digital management said that the disk contained 64GB of NAND.



WD Has always prioritized the use of their WD Red Pro series of Hard drives when deploying NAS systems with larger numbers of individual drives bays, as well as in recent years ensuring that larger capacity HDDs arrived either on the Pro tier first or exclusively in the long run (as these larger drives are considerably more industrious in design and architecture. But what is the Difference between a WD Red and WD Red Pro NAS hard drive?

When will the WD Red Pro 20TB NAS Hard Drive Be Released?

Although the pricing on the WD Red 20TB NAS Hard Drive is still going to be very much based on your region, the drive has already appeared available for sale in a number of online retailers (with several listing 1x unit of this drive at $760 (though you would need to factor tax, profit margin, etc), as well as the drive appearing on the brands’ official product pages HERE, so the release is pretty much immediate. That said, stock on these larger drives at initial launch is always a little thin on the ground and we can expect global availability on this drive to be quite low at the start.
