So Far So Positive

Pros: 10tb WD Red
NAS/Desktop Use

Overall Review: I bought 3 x 4tb drives of the same label and they are still in use 2 years later. I have decided to upgrade my NAS storage to 4 x 10tb Reds. We will see how long they last.

Manufacturer Response:
Hi Anonymous,

We regret to hear about the noise issue with the WD Red NAS hard drive and appreciate your time for providing the feedback. Please know, some noise will occur during normal drive operation. The type and volume of noise are dependent on whether the is drive performing a read/write operation or idle with the heads parked. We have placed a few helpful links below providing more information for your convenience.

"How To Tell If The Noise or Sound An Internal Drive Makes is Normal":
https://support-en.wd.com/app/answers/detail/a_id/16309

Please ensure that the internal drive is connected properly on the SATA port of the computer on both ends and to test the drive on Windows computer using our Data Lifeguard Diagnostics program by connecting it on a different SATA port of the computer and a different computer.

If the test is inconclusive or showing the result as failed and you have recently purchased the drive then you can return it to the place of purchase. However, if the product is past their replacement policy, you can create an RMA through WD and replace the drive if it is under warranty.

Quiet NAS drive

Pros: Quiet. Easy install.

Cons: The drive has some heft, but I expected that. At 10TB I'm sure there's a few plates in there.

Overall Review: I bought this for a home media server. Trying to fill 10TB today reminds me on how much space I had to fill a 3.2GB drive back in 1998! It seems endless.

10 TB, solid like my other WD drives

Pros: - no setup (okay, true for all drives)
- reasonably quite (not silent)

Cons: - none

Overall Review: I definitely recommend these. I have 2, 6 and 10 TB Red drives and have never had a drive failure or even lost a byte, as far as I know. I'm not a heavy user in terms of number of reads and writes, but I rely on these drives daily. The 2 TB drives are at least 5 years old, and the 10 TB is only about 6 weeks old. They are now all in a 4-bay Synology NAS, where I will swap out the 2 TB drives for 10 or 12 TB drives as my needs grow. I haven't measured maximum data transfer rates individually, but the NAS can saturate my gigabit network when I'm moving big files.

10TB, good hard drive, quiet, low power

Pros: I got 5 of these for a NAS server. I wanted big, quiet, low power, and reliable, but didn't need lots of speed. These fit my needs. They were well packed. They arrived in 5 individual corrugated cardboard boxes, with shock mount padding. Then all 5 boxes were inside a larger corrugated cardboard box with air pillows. All 5 arrived intact. They all spun up. None made any odd noises. All 5 passed a smart offline short test. I'm running the smart long tests, but they'll take 18 hours.

Cons: The product description is too terse. The specifications don't list the sound level or the power requirements. I wanted these for bulk storage, and didn't need speed. For people who do want speed, look elsewhere, these are only 5400RPM.

Overall Review: The sticker says they use .40A at 5VDC plus .55A at 12VDC, ie 8.6 W per drive. I don't know if that's startup or continuous. I don't have any way to measure the sound level, but they're very quiet. The case fan makes more noise than all 5 of these together.
