WD Red Plus 4TB NAS 3.5" Internal Hard Drive - 5400 RPM Class, SATA 6Gb/s, CMR, 256MB Cache

I contemplated using WD Red SSDs instead of HDDs as I've heard many complaints about noisy HDDs in NAS. I specifically selected the 6TB variant as it appears to be the largest NAS HDD variant with 5400 RPM; HDDs rated for 7200 RPM are considerably louder and generate more vibrations in the NAS.These 5400 RPM disks are excellent and quiet, would recommend them for anyone looking to build a quiet NAS, without spending 3x the money on WD Red SSDs.

I have been purchasing HDDs for many decades now and I am sticking to the Western Digital brand because I trust WD to reliably store my data (all personal, including many TB of family video). Some HDDs are on 24/7 with constant access and can get hot, especially when the ambient temperature is high during summer, and I choose WD Red for these more demanding uses.As a personal user, I carefully pick the size and style (e.g. Green Blue Black Red, Red Plus, Red Pro) to give the best price per TB and performance for intended usage. I am paranoid about preserving data and have a rigorous strategy of redundant usage and multiple backups which I have had to prove on occasions due to human error.I do not expect HDDs, from any brand, to last forever though some are still going strong after 20 years with no hint of degradation. In my experience, a few % of HDDs start to show signs of problems after 5 years, and I constantly monitor the raw read error count. These WD HDDs keep going reliably with 100% data integrity for years after the first signs of problems, allowing me time to choose how to retire/replace. I have never had a WD HDD fail catastrophically, it is always a graceful degradation, hence why I trust WD to look after my data.

Great Product

Replaced my Toshiba P300 with a 4tb WD Red. Used for storing photos, etc. 5400rpm is very quiet compared to the 7200rpm on the P300.Would never buy another Toshiba. Drive lasted no more than 3 yrs and started reallocating sectors.

WD Red Plus 6TB NAS 3.5" Internal Hard Drive reviewI bought these to replace Seagate drives that I've had nothing but trouble with the past few years, A. being ridiculously slow and B. lately just completely dying on me after just a few months use.So far the WD Drives have been good and the speed is reasonable for spinning rust HDD's, around 160mbps copying largish media files and they're very quiet in use, I use these for Plex and they are more than good enough for that, the test comes with time and seeing if they last better than the Seagates did.I will report back in a few months if I have any issues.From what I've read there's been quite a few instances of people buying drives listed "New" and the build date on the drives being somewhat older than when they bought it thereby lowering the warranty period, I'd suggest it's always best to go on the manufacturers website and check with the serial number which is easy to do, these had a build date just a few weeks before I bought them, so absolutely fine.Time will tell but so far I'm pleased with the WD Drives.

Disk failed within 30 days.Contacted Western DigitalThey wanted me to pay to return it then it would take 3 weeksAmazon were great and have processed a return and a refund.I'll be steering clear of western digital in future.

In warranty, no bad sectors. So far so good.

Good quality work perfect.Thanks
