Review: My data on my terms. - This review is for the Western Digital 20TB WD Red Pro NAS Internal Hard Drive HDD - 7200 RPM, SATA 6 Gb/s, CMR, 512 MB Cache, 3.5" - WD202KFGX. The products arrived on time and in great condition. I bought these to install them into a UGREEN interface. I wanted to use them as RAID drives. The UGREEN device supplied mounting hardware for these drives and everything lined up correctly. I installed the drives and formatted them using the UGREEN interface. Please realize that when you format two 20 TB drives as RAID drives, formatting can take up over a day to complete. So, don't be in a hurry and don't think there is something wrong when it just doesn't happen in a flash. Both drives worked perfectly and I am very pleased with how the UGREEN interface uses them. The reason that I got the interface was because I had recently lost a USB hard drive that was connected to my computer. Not sure what made the drive go bad, but all attempts to recover the data from the drive were futile. I could send the drive off to some places that recover data, but that can cost into the thousands. I was looking for a replacement hard drive like the one I had and then I read a review from someone who lost the information off of his hard drive and he made a great point. The manufacture of the hard drive will stand by their warranty, but you must send your old drive back to them before they will send the new one out. He was not comfortable with letting a hard drive company have his old disk with all of its data. The company could easily fix what was wrong with the drive and possibly collect all of the data that is on it. That might seem paranoid, but I have had too many hackers take over some of my accounts online and I don't want anyone having access to my data. So, instead of just buying a new hard drive that could one day fail again and lose all the data, he suggested buying this UGREEN interface with two to several hard drives set up in a RAID configuration. In this configuration, if only one hard drive fails, you still have all of you data on the other hard drive. This way, if you need to send the hard drive back to take advantage of the warrantee, you might be able to just reformat the old drive if it works at all and then send it back for the replacement. However, if the drive is too far gone to reformat it, you just forget about the warrantee and order a new hard drive. Since you data is safe on the other drive, you don't have to worry about losing it. You get the new drive and put it into the interface and the interface automatically syncs the new drive to all the data. You at least have a chance this way to take advantage of the warrantee and you maintain your data in a safe place. If you can't take advantage of the warrantee on the hard drive, then you can take a sledge hammer to the drive to destroy its ability to impart the data to anyone. This just made more sense to me. And the added benefit of this UGREEN interface is that you don't need to connect it to a computer through the USB. You connect it to your home network using an ethernet cable. Then with the UGREEN app, you can store and retrieve your data from any of your devices on your network. This is like having your own cloud storage, but it is in you house instead of being out there in the ether. And you can reach the drive remotely when you are away from home as long as you have internet access. I have a DROPBOX account, but I am thinking of backing up my DROPBOX data onto this drive. Then, if I am home and there is no internet, but my home network is still working, I can get to all the information that has been stored on DROPBOX because it is also on my home network drive. I have been using the UGREEN interface for several weeks and it and the two hard drives have been functioning great. So, this is something to consider.
Review: It’s a Hard Drive. It’s Big. That’s Pretty Much It. - So, here it is: the Western Digital 18TB WD Red Pro NAS Internal Hard Drive — aka the “Big Boy” of data storage. What can I say? It’s a hard drive. It’s quite big. Like, “I could bench press this if I really wanted to” big. But please don’t — it’s expensive. 18 terabytes of space means I could theoretically store every embarrassing photo, weird Spotify playlist, and downloaded PDF I’ve ever made. The digital equivalent of a hoarder’s dream garage. Installation was straightforward: slot it in, screw it down, pray to the tech gods it spins up on the first try. Spoiler alert: it did. No strange noises, no smoke, just pure, reliable mechanical magic. Pros: So much space, I could hoard cat videos for decades. Designed for NAS, which means it’s the responsible adult of hard drives — steady, dependable, and ready to work overtime. Quiet enough that I almost forget it’s humming away, plotting how to store my entire digital life. Cons: It’s heavy. Not “drop on your foot” heavy, but “maybe I should use two hands” heavy. No flashy lights or cool holograms, just good old-fashioned spinning platters. Does not come with a personal assistant to organize your files or delete your bad decisions. Final Verdict: ⭐️⭐️⭐️⭐️⭐️ – 5 stars. It stores data. It’s big. It doesn’t complain. Honestly, what more do you want from a hard drive?

## Questions & Answers

**Q: 4 of these drives good for 32tb 24/7 dlna nas server? Don’t want to beat a dead horse here... Really it’s just to stream my 10Bit 4K movies using DLNA**
A: It all depends on what size and what RAID configuration you are asking about.  Most people would be using RAID 5 or something like Synology's SHR (similar to RAID 5 but doesn't require equal size hard drives) for this purpose. If you are thinking that 4x8TB will give you 32TB of storage that is not correct in RAID 5 because of the overhead used for data protection.  It works like this for RAID 5, 4x8TB = 24TB storage, 4x10TB = 30TB storage, 4x12 = 36TB storage.  So first determine which RAID configuration works best for you and then find a RAID calculator available online to choose your RAID configuration and hard drive size.  If you just want speed, with no parity checking then you could go with 4x8TB or 2x16 TB (whichever is cheaper) in RAID 0 for 32TB of storage but file corruption could be an issue and there is a possibility that you can only do 2 hard drives in RAID depending on your hardware.
Having said all that, these drives will certainly stream 4k 10-bit HDR movies over DLNA.  Streaming 4k is just as much up to the software and hardware of your computer than it is the hard drives.  A nicely configured Windows machine, for example, may stream them fine however a less powerful NAS device may not.  There are a lot of moving parts but these drives will not be an issue.  There are also issues with playing the 265 codecs in Windows 10 Media Player but the same files that will not play in Media Player, will stream via DLNA to my LG TV just fine and play in full 2160p HDR with no problem.  These same files will show up fine in my 9 year old NAS but will not stream via DLNA on it but photos stream fine.  So it all depends on your exact configuration.  But the drives are fine.
If it all gets too hard then just get a fast (say 400 MB per second) USB stick and copy 10 movies at a time on to it and plug it into your TV.  The Samsung BAR Plus 256 GB works well for this in my experience.  You can also look into getting streaming server software on your computer and a client connected to your TV.

**Q: What is the difference between this and the WD Black drive?**
A: The Red is engineered for 24/7 usage.  The Black is not.

**Q: Is the red wd drives better for cctv/nvr in raid setup than the purple drives? i hear purple drives are not lasting long. both red and purple are 24/7**
A: I use my purple drives with 9 cameras 24 x 7 and have over three years without a single failure.  pretty good if you ask me.

**Q: Can I use this as an external storage for my desktop?**
A: I have four of the earlier 3tB versions of this drive in external USB3 enclosures and use them in rotation for critical full system backups. They have served very well in that capacity. I also have one of the 3tB drives in my main daily-driver computer now and it does that quite well although it isn't as fast as some but since it is used mostly for secondary data store it doesn't matter so much. The reason that I have so many of the older 3tB drives is that I upgraded all of the drives in my Drobo NAS to 6tB drives a while back. Those drives as well as five of the 8tB units in another NAS have worked perfectly so I can highly recommend them (for the proper use, of course).

### ⭐ DOA - makes weird noise and doesn't spin up! BEWARE
*by K***S on November 8, 2022*

I bought two of WD Red PRO 18TB in October when they were on sale to replace the current disks in my Home Backup NAS. I bought 2 because I need two identical drives for the NAS. Disk 1 arrived a few days later and disk 2 arrived a few days later. And now the problems begun: Disk 2 which was sent to me wasn't an 18TB drive, it was only 6TB! A harmless mistake? Fraud? Who knows... Very annoying anyways... Now I tried to get disk 2 exchanged, but Amazon could only offer a refund, because the drives were out of stock with unknown restock date. Too bad because I didn't want a refund, since I got the drives for a good price and now they were more than 25% more expensive... So I had to wait about 3 weeks for the disk to be back in stock and be able to have it exchanged instead of just getting a refund. Today the exchanged drive finally arrived. This time it was as ordered 18TB. I installed both drives in my NAS. One drive was GOOD the other was recognized as BAD during the drive self test. The temperature reading was off and caused a S.M.A.R.T error. In fact there was no temperature reading at all for 1 drive. So I let the drive warm up for a few hours and tried it again. Same thing. SMART could no be read and there was no temperature shown for 1 of the 2 drives. I took both drives out of the NAS and tried to see what's going on by installing them in a Windows PC. One drive is fine. SMART is OK. No errors. The other drives just makes a weird repetitive noise and doesn't spin up. It's not recognized by windows. It's DOA (Dead On Arrival)! I checked which drive it was and it was the 2nd drive. The one I received as replacement today! So after the long wait and the whole odyssey of exchanging the drive the drive arrived DOA. Was it bad luck? Maybe. Do I trust these drives? No, not anymore. Never had a drive DOA. This was by far my worst experience buying Western Digital drives on Amazon! And I have quite a lot of them (in total probably about 16 different WD Elements and MyBooks). Since these 2 drives were supposed to be used in a NAS which should hold the backups of my personal and work PCs I thought I'd buy the more expensive "real" WD Red Pro drives, which are designed for 24/7 operation, but what did I get? Just a way too long frustrating experience overall. Maybe I was just unlucky in this case, but I never had a problem with a shucked drive. So back to shucking external drives... I CANNOT recommend the WD Red Pro 18TB drives at this point. PS: the HDD came in the original Western Digital box which then was packed in one of the thin Amazon air bubble envelopes. Maybe it's an issue that the drives aren't shipped better protected? Not sure. The delivery driver dropped it off quite carefully, though. No idea what happened to the drive in between...
