Model overview based on user reviews
WD Red Plus is a NAS-oriented HDD that combines CMR technology with relatively quiet and efficient operation. Its main strengths are quiet multi-drive use and moderate power consumption, while performance is only adequate for NAS workloads and may disappoint in demanding transfers. One user also reported periodic clicking, and another described a serious reliability failure, so quality may vary between units.
Pros
Cons
The drive is a pretty good compromise in terms of speed/noise/power consumption. It's quiet in operation, but there's an annoying thud every few seconds, and this thud isn't absorbed by the PC case, but I don't know of any better options. Unfortunately, switching to 4kn mode is quite complicated (WD Hugo). It's worth considering, except in cases where you really need speeds over 200MB/sec or power consumption in standby mode (when the drive isn't spinning) - you should look at other models. I will also buy the same or a similar one from the Pro series as soon as they are available at a good price. Relatively low power consumption and noise, helium, adequate starting currents No logical sector change mode like in Pro versions  Volodimir: use WD WD120EFBX few months |
I bought a 4 TB WD hard drive from Rozetka. It worked for a while and started beeping, knocking and grinding. It didn't read, didn't write and froze. The test program gave a million errors and hundreds of used sectors. I took it under warranty. They sent it to the service center. And from there they called and said it's WORKING We're sending it back to you I read a lot of reviews about Rozetka - I'm not the only one, there are thousands of cases And I realized that they don't care about reputation, the main thing is money And then they send the client away. I don't advise anyone to buy anything expensive from Rozetka. If a warranty case occurs, they'll just send you after the Russian ship Volume Unreliable  Andrey : use WD WD40EFPX more than year |
