I do not trust the company in question. I have lost very important information even in the red edition which is considered high quality. What a pity!

Purchased 2 years ago and still works perfectly. It is connected to a media server that runs constantly and has not had any issues.

I got this specific one for desktop use (yes, I know that red ones are not meant for this use, but blue ones are, but I wanted something that could withstand 24/7 use and lots of read/writes and had a long warranty). It worked fine at first, but after 6 months it became painfully slow. I thought it was just bad luck. I spent a whole day trying to save what I had inside because it was transferring at a snail's pace. I got it replaced and everything was fine...until the second one also failed in the same way after 6 months. I thought it was just bad luck again and got it replaced. The third one had the same issue. Obviously, I had fallen for the SMR trap. I switched to WD Purple for the same reason I got this one, and it has been working perfectly for 4 years now, so I got a second one. Unless you can find it in CMR (EFRX), stay away from red!

For non-RAID systems: The disk is reliable, fast, and relatively quiet.

For NAS: WARNING! As mentioned by another (sympathetic colleague), WD replaced the technology from CMR to SMR without announcing it. SMR works perfectly on its own but is unacceptable in RAID/SHR. Therefore, be careful with the disk model. Prefer EFRX instead of EFAX.

Let the newcomer understand

The product is good!

I have them on a NAS with 4x4 disks. They will be 6 years old this summer, running 24/7. They are excellent. They have paid for themselves

We have 12 such disks and we use them in a NAS. After 3 years of use, only one disk failed. Very reliable.

I have had it for a little over a year and it has approximately 10,000 hours so far. Currently, I haven't encountered any issues but of course, the disk has a Mean Time Between Failures (MTBF) of 1,000,000 hours, so you never know when it might fail. Overall, I have had a good experience with WD (over 7.8 disks that have been running for years).

The speeds are okay for a 5400rpm disk.

Looking at the statistics from the data center (https://www.backblaze.com/blog/hard-drive-stats-for-2019/), we can see that a year or two ago, it had an Annual Failure Rate (AFR) of about 2%, although their statistical sample was not large. Nevertheless, it is similar to Seagate in its category.

Whether it's WD or Seagate, the bottom line is that you can't rely on just one disk, you need a backup

It has been installed on Synology DS218. The noise that may be heard in quiet surroundings when recording is perfectly normal when speaking about a distance of 30cm from the head. I cannot judge its reliability yet.

For a homemade NAS, it's just what you need, even if it's SMR, the difference won't be utilized at a hobbyist level of simple NAS use. Also, since I changed both old hard drives with two of these, nothing can be heard from the PC even if they copy something. It's like they don't exist in terms of noise, no matter what I do with excellent temperatures.

Great caution should be exercised with WD Red < 8TB drives with huge cache (256MB). Due to cost reasons, WD changed the recording technology to SMR without any announcement, resulting in several issues, especially in RAID usage, particularly during rebuild/resilver.

Theoretically, they are extremely reliable, have low temperatures, and are designed for use in NAS 24/7 with a three-year warranty and vibration protection in all versions.

However, they are slow as they run at 5,400rpm, while their noise level is reasonable.

That being said, the two disks I had on a Synology DS414, purchased in June 2015, developed bad sectors almost simultaneously in 3.5 years.

The other two disks on the same NAS are half a year old and have no problems at present.

Despite the above, I still bought equivalent disks (with larger capacity) to replace the existing ones as my experience with Seagate disks in the past prevented me from trying them.

An alternative that is faster is the same disks in Pro that run at 7200.

Four identical disks on QNAP. After 2 years and some months, one of them "died". Just in time for the warranty to expire and get a new one. I suggest the corresponding Pro model which has a 3-year warranty.

A very good disk from WD. I bought it to store data. It's not the fastest disk but it's definitely reliable (at least for now, I hope it doesn't break down because I'll cry), completely silent compared to the WD Black I have and it didn't go above 35 degrees Celsius in the summer. Recommended!

Although it is for NAS Storage and Servers, I bought it for a computer hard drive because I was going to get a Caviar Green but with such a small price difference and much better performance in speeds, I chose this one. It is a very good and quiet hard drive with very good speeds and even in an environment that has some vibrations, it has not suffered anything. I have also used it in a Server with Raid 0 (10 identical drives) and there it has very good speeds especially. Recommended for servers and computers.

The disk was purchased for storage on a home server. From the first moment, it operates at very good speeds and relatively low noise. I consider it a value-for-money choice for such uses and would buy it again without hesitation.

Those who look at these specific disks know the reasons.
I "cut" one star as it could make less noise.
Apart from that... one of the best choices for NAS systems.
