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.


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.

Synology SRM 1.3 Review – General Security & Safety

Regardless of whether you are a home or business user, the security of your network is going to be one of your priorities very early on. Both internal network security with the devices that are exchanging packets of data via the router, right the way to how the router governs and manages the stream of data coming from your internet connection, if a router isn’t particularly secure, you will all too quickly find out! Worse still, if you are an inexperienced network technology user or a business lacking in-house IT support, then the ease of configuring a router to be as secure as possible within your specific network environment is going to be even more of an uphill battle. SRM 1.3 tackles this in several very clear ways. First off, despite its incredibly user-friendly browser GUI, the majority of its more potentially insecure architecture elements (i.e those that if you mishandle them or let them open could be disastrous in the wrong hands) are either disabled by default or are locked behind more advanced configuration windows/portals. Some are more obvious than others, such as port forwarding (common to all routers and not something anyone should touch without reason) settings and IP/Mac address blocking, which are all quite useful, but common. However, there are little things of note that are impressively specific to SRM 1.3, such as the power-use admin account being disabled by default. Something that even now in 2022 is still not the case for many routers (including ISP ones) and with those same power user crenedtials printed on the base of the router.

Additionally, all devices (both current and for a period, historical) are monitored in SRM and this allows you to monitor their behaviour, block them, label for for later use in ‘Safe Access’ or simply keep an eye on their behaviour.

If you had additional SRM 1.3 software user accounts, there are several options for restricting an accounts access (IP locking, resritcing individual app/storage access, removing SRM 1.3 dashboard access, etc) and that also extends to auto-block methods that will change the parameters for a scenario where someone is trying to log into an account erroniously.

When it comes to what services, features and applications the router with SRM 1.3 is running, there is a single portal full control list that allows you to quickly disable these quickly in the event you need to shut everything down tight or just want to troubleshoot each service one by one. This list of services and level of control will differ on whether you are using the router as a primary or secondary system, but this single page means to shut down any active internet/network service is really handy.

Then there are the inbuilt firewall settings that allow you to use present configurations for securing your internet access point, as well as the means to create a much more customized set of firewall rules. It has to be said that the bulk of things covered in security in SRM 1.3 so far are available on the bulk of prosumer routers, just not presented in a way as user-friendly as here and not to the same extent in most cases.

Then there is the inclusion of the Synology VPN software within SRM 1.3. VPN Plus allows your Synology Router to host a powerful VPN server that is easy to set up and manage. It supports SSTP, OpenVPN, L2TP over IPSec, as well as Synology’s own SSL VPN protocol and lightweight desktop client. Web-based portal VPN gives users direct access to company intranet sites and there is even an option to provide employees with browser-based remote desktop access. The Synology VPN is a service that supports SSL fast authentication and encryption access to webpages, files, and applications on the Internet (as well as local networks). Here, you can customize things like the Client IP range, Self-owned domain name, ports, security level, authentication, and others. You can also enable split tunnelling, which allows users to connect to destination webpages, applications, and servers in certain local subnets or local IP ranges.

Each Client VPN Access License allows one concurrent user account to use Synology WebVPN, SSL VPN and SSTP, with permanent validity upon activation. Every Synology product that supports VPN Plus comes with a free license. To add more concurrent user accounts at no additional cost, simply sign in to Synology Router Manager (SRM) as an administrator to activate additional free licenses. You can assign permissions to more user accounts than installed licenses. All the accounts are given access on a first-come, first-served basis. When the license quota is reached, no more accounts will be given access until other accounts are disconnected from all Synology SSL VPN, WebVPN, and SSTP services. Once a user account is connected to VPN Plus and starts using any of the three features, it will be allowed to use any of the other features on the same or different devices at once without requiring extra licenses. Each additional connection beyond the first requires registration of a free license.

Features Pre-installed free license Additional free client VPN access licenses
Service Synology SSL VPN 1 concurrent account Up to product specifications
OpenVPN Unlimited connections (up to product specifications)
L2TP over IPsec
Management Real-time traffic monitor V
Connection history V
Service-based permissions V
Bandwidth control V
Block list V

For those that want to get even more beefed up in the security stakes when accessing the controls and complete GUI of SRM 1.3, you also have the option to create/install a secure tunnel with free and easy installation of the Let’s Encrypt certificates from within the control panel. This is a small extra that you can of course manage for the most part with many other paid certificates if you prefer, but it is still good to have this option available from within the software and that it guides you through the process too.

Speaking of guiding the user through the process, SRM 1.3 also includes the Security Advisor tool (much like the one found in NAS and DSM) that analyzes your system and then provides you with details on how you can strengthen the safeguards, settings and setup of your router. The extent to which it will check and report can be configured in its settings menu, but even in the default configuration, it is quite thorough.

Upon completion of a scan, SRM 1.3 will then provide suggestions on what you need to correct/improve upon. Again, a lot of this is going to be a bit comment-internet-sense-101 (eg don’t use ‘password’ as your password), but it does include several more business-focused recommendations if you chose that level of scanning. The scanning with the security advisor can be triggered manually or set to a regular schedule from with the software and can also be linked to notifications if a potential vulnerability or router weakness is highlighted. This then allows you to connect with the router, access the severity of it and then proceed accordingly.

When it comes to accessing the router and SRM 1.3, local access (eg from on the same network) will be relatively straight forward and unless you have blocked SRM access on a specific account or your IP/Subnet/etc are different to the system, you should have fairly direct and secure access up to this point. But what about remote/internet access? Sometimes you will want to access the router and SRM 1.3 to quickly access a setting/service (perhaps for IT troubleshooting or simply a family memory having difficulty with the network). In that case, you can use the popular Synology Quick Connect service (much like their NAS) to tunnel into the router and SRM 1.3 securely from anywhere in the world, via Synology’s encrypted servers. This is a completely free service that is included with ALL Synology products and can also be customized to only allow access via very specific means and by very specific people too.

Then you have ‘Safe Access’, one of the jewels of the crown in SRM 1.3. I will go into more detail on the Safe Access service later on, but in terms of security, alongside a whole bunch of ways to craft a safe and trusted internet access point for your router users, Safe Access also allows you to enable forced Google Safe Browsing and enable the Threat Intelligence database tool. So, let’s go through these two forms of network protection, what they do and how they help.

The safe search functionality allows you to automatically shift the results of popular internet search tools and some social platforms to automatically enable ‘safe’ mode or disable any NSFW content. This will also overwrite any custom policies that users logged into those sites will have (i.e having a Google account logged in and set to show all results’ will be overwritten by the router enforcing safe search rules). This is a feature that is widely available on ISP routers and other paid premium routers, HOWEVER, on those you lack the scaled options of off/low/moderate/high, as well as the option to scale these to individual users/devices on the system and different policies to different sites. Eg you want your employees to have full and unrestricted access to YouTube and Social sites for marketing purposes, but want adult content restricted on typical Google search results in the workplace.

Now Synology’s Threat Prevention dynamically guards the security of your Synology Router as data is handled and manages packets on network devices by inspecting Internet traffic to detect and drop malicious packets and also records network events, for statistical analyses regarding malicious sources to check their severity. Threat prevention is arguably less advanced in its architecture compared with Safe Access, ut is still a great tool in a much broader way.

Click to view slideshow.

Understanding the difference between these two approaches to protect your network and your network client base is quite straightforward. They represent two different approaches to your network security. Safe Access is DNS-and IP-based. It integrates several external databases (including Google Safe Browsing) that identify domains and IPs related to malware, phishing, botnets, command and control servers, social engineering, etc. When a device in the network attempts to access the blacklisted destinations, Synology Router prevents the connection from even being established. Threat Prevention, on the other hand, is signature-based. It monitors incoming and outgoing traffic using Deep Packet Inspection (DPI) – not just checking the domain or IP – and is able to drop any malicious packet detected in real-time. In addition to Internet attacks, Threat Prevention can alert you to inappropriate user behaviour, such as sending passwords through unencrypted HTTP traffic. Both packages work automatically. You can review the event logs and adjust the actions, but even if you don’t, they still silently protect you in the background.

The know target lists and algorithms that each of these tools (and other connected databases that feed into the intelligent actions and alerts) are updated regularly in the system database and by default, these are automatically downloaded to their latest versions. It is recommended that you never change these settings.

Overall the background and passive security settings that are configurable in SRM 1.3 are not an enormous leak, at least in terms of the broad result, than more premium routers in the market. What sets SRM 1.3 out from them though is that it is presented in a much more user-friendly fashion, is considerably more scalable and provides a considerable amount of flexibility that most other routers would limit to an ON/OFF switch. The Threat Prevention tool is can be a little underwhelming (perhaps needing more attention than it has, especially compared with Safe Search) but overall the security and safety of internet connectivity via a Synology router and SRM 1.3 is still very good.
