Remember when everyone said that hard drives would be dead by 2020? Yes, to say that statement has been debunked so incredibly thoroughly that it seems a bit comical to think that HDDs were going to go away any time soon. Yes, SSDs still continue to become more affordable AND faster with each generation (PCIe Gen 5 clocking in at 12/13GB/s), but HDDs will ALWAYS have the advantage of just sheer capacity and value for money - with the new WD Red Pro 22TB hard drive being a prime example of why this storage medium continues to thrive. Arriving at a steep £609/$690 price tag, still manages to maintain the same level of price per TB of its' smaller capacity alternatives in the portfolio - but with a staggering 22 Terabytes of capacity available, spread over 10 2.2TB platters and benefiting from on board to improve internal operations and space conservation. It even arrives in CMR/PMR format, so concerns of these larger drives only arriving in SMR design are out the window too. The 22TB is a big deal in many different ways and if you are in the market to buy a new server and want to prioritize storage capacity, this drive has the potential to turn a 2-Bay into a 44TB cupboard beast, a 4-Bay into an 88TB Monster and an 8-Bay into a potential 176TB behemoth! Of course, drives like the WD Red Pro series are designed for even bigger system deployment (up to 24 Bays in fact - which would cross half a Petabyte of storage) and you should always factor in your RAID/Redundancy, but right now this is the biggest commercially available HDD for NAS in the market and in terms of futureproofing your archive or your warm data storage - this drive is tremendously compelling! Today, I review the WD Rd Pro 22TB NAS drive, run our PC benchmarks, check compatibility with Synology & QNAP NAS systems and benchmark the drive there too.

I want to share something about the noise and harmonics of these drives (WD221KFGX).
I have two NAS: DS3622xs (10 x WD120EFAX & WD120EFBX)+ (and a DS923+ (3 x WD221KFGX). They are in different rooms so I can compare them.
So yes, 5400rpm (12Tb) drives vs 7200rpm drives (22Tb) should not matter much..but. as much as I can work all day near my DS3622, I can't even stay focused near the DS923+ with the 3x22Tb drives. I can even hear those drives seeking in another room. As much as my bigger NAS is office-silent, the smaller one is so noisy I'm thinking of putting it in the garage. Reminder to myself: dBA's are -exponential- :(
Thanks for the feedback it's very useful as i'm also planning to get a DS923+ with a 22tb red pro. Did you have any compatibility problems with these particular disks or they run just fine in DS923+?
@@sparrow2a Absolutely zero issues. They run cool (34C-36C) and the NAS is virtually silent until one of the drives starts seeking.
I upgraded my 923+ to 32G RAM to be on the safe side wrt to filesystem cache (it's 66Tb raw, after all). Pretty happy with this unit.
@@vincentcojot6578Thank a lot for the feedback that's very helpful I'm gonna get the DS923+ with the 22tb red nas pro
The problem I have with big drives is there is almost a guaranteed chance for a bit error on a rebuild so you have to run raid 6 or higher. You also have a bigger chance of a drive failing during the longer rebuilds. Until they get the non recoverable error rate high enough and the drive speeds up to 12G or higher the chance of these failing is higher, plus because you have so much data on them (assuming you are using the full capacity) you are subject to more data loss when the drive fails.
That is why you should rather build yourself a FreeNAS/TrueNAS box with ECC RAM and take advantage of ZFS over plain old Linux RAID 5 in a Synology etc. I do not have enough data to personally justify doing that, so I keep multiple backups instead, but if a friend with a small business etc asks, that is what I tell them.
Just no. Get enterprise. End of story.
20TB Red Pro is 54% more expensive than 20TB Ultrastar atm, depending on region ofc.
I recently bought 6x Exos X18 18TB for around 1600$ (including VAT taxes). Configured them as a Raid-z2 pool for the project I am working on. My general thinking is - get in bulk quantity whatever is on promotion today. Buy the "latest and greatest" only if there is a specific feature you need.
You got those hdd at very good price . Usually their price is going like 545 usd per unit ... Surprising enough 😯
@@DCW_B63 the price is very different based on the "features" - encryption, SAS, etc. I got the barebone one ST18000NM000J. And yes - the deal was good, thus look for what is out there, there is always one.
Just picked up 2 x 20TB of this drive (WD Red Pro) from WD website direct for $599 combined (sale bundle). Putting them in RAID1 with a rPI 4 NAS.
Seagate Exos 20TB are better on paper with specs, hope they come out with 22+ models or even the new HAMR drives that are only in enterprise test servers.
I bought WD exclusively before I started using NAS two years ago. I read statistics on hard drives and ended up exclusively using Seagate Ironwolf for my NAS. Lately started to wonder whether I should have half Seagate and half WD for my NAS to spread the risks. What do you guys think?
i think it's more important to have different batches of whatever disks you are using, to minimize the risk of defective series.
I have been more gearing towards the WD Gold and see that WD have a deal on 2 RED PRO's 22TB right now a bundle deal. Thoughts? Gold vs Red Pro?

you telling me you don't like computer noises? I have been silently desiring for my PCs to make IBM PC AT noises for months now. I would totally plug just a IBM PC AT audio emulation device into my SATA port in my Alienware if it meant I couldn't use it for storage.
also, per TB on average, HDDs are cheaper, but if you get a HDD and a SSD of equal storage number AND speed, you're looking at pretty much the same price as I heard.
4x 22 TB gives you 66TB of storage in RAID, unless you are insane and do not use RAID. ;) Technically, it is 5x 22TB, because again, unless you don't really care about your data, you would have a spare lying in the shelf already. Or else you might freak out when the next supply chain issue hits and you cannot find a replacement for 5 weeks...
4x 22TB gives you roughly 40TB of storage in RAID6, because with similar failure rates and random errors, despite higher capacities, it's way more likely to loose entire pool of data with just one disk fault tolerance of RAID5 or SHR-1
Buyer beware. 22TB simply is not compatible.. I've just bought 2 of them and can't use them on Synology and on my Terramaster. The Synology says can do it. and the Terramaster just locks up with solid green lights.
Does moving of this internal data to flash means that if I put data on disk, disconnect it and leave it for say 3 years not plugged in, there is a chance that I will not be able to read data from disk if something is missing from that 64GB flash storage?
More likely the heads encounter stiction problem than flash discharges. I am more worried of flash wearing out, but I thing it is no issue in real world usage.
How well will this WD 22TB drive work with 6 Seagate Ironwolf/Exos drives in my Synology DS 1821+?
Can I add two WD 22s to fill out my 1821+?
If I understand the test done in the full drive review, you added single wd22 to a Synology nas and it worked. I.e., they played nice together. Am I correct on this perception?
10 platters in this drive = 10x the chance for a drive crash.
Awesome
awesome
Red are too expensive ... for what they are.
"awesome"
complete junk analysis. saturating 10gbe, yeah, sure. in sequential reads. when most workloads are involving random seeks and latency scales only with more drives.
