1 out of 5 eggs Long review, lots of info - 5 failures from 6 4TB HDD's 03/30/2014

This review is from: WD Red 4TB NAS Hard Disk Drive - 5400 RPM Class SATA 6Gb/s 64MB Cache 3.5 Inch - WD40EFRX


Very large capacity - but trusting this much storage space with your data means that it HAS to be reliable. They aren't. See below.

Gave this 1 egg because the sheer number of failures I caught!


See "Other Thoughts" on my testing methodology. It can help others with their HDD installing and testing ideas.

The first WD 4TB Red I bought two months ago passed all of the tests that I perform on new HDD's, and it has been working fine in my QNAP NAS. I just decided to buy another 6 HDD's and scale it up. After arriving this week, 5 of the 6 HDD's failed. This was in a proper ESD protected environment, with much care also given to handling and mechanical damage.

HERE IS THE CATCH: If I had just installed them in a NAS or PC, several would have configured and seemed to run ok, causing all data to be lost when they did eventually stopped running. I think only *** one *** would have came up DOA due to no HDD controllers being able to see it. The others failed the WD testing software - BUT they all four came up in Windows fine! A note to others installing their own HDD's. Just because Windows sees it does not mean that it is ok.

I am an experience engineer with many years in reliability testing and R&D design. The sheer number of failures here indicates that it is a **** WD design issue **** and not anything like Newegg handling or random ESD events. WD needs to get their act together and fix these - because they are upsetting their customers in droves. Me included - a loyal 15 year customer. The Newegg packing was great and I feel well protected the drives.

See more below.

Other Thoughts:

I thoroughly test all HDDs since having many HDD failures over the past 12-15 years. I run each HDD through the vendor's test software, in this case, WD's Data Life Guard diagnostics software. Follow that with burn in using Passmark's burn-in SW.

Another very useful tool to use is HD Sentinel. The free version is not useful (at all) except to see what it can do in the greyed out menu options. But it watches the SMART values for you and notifies you when they start ratcheting up, before the HDD failure actually happens. A real gem!

Last note: Anyone not using ESD protection while handling any open electronics is playing with fire and is going to eventually have an unknown "failure", so I am very careful with ESD. As an engineer, I view not taking ESD precautions as being "blissfully ignorant". This is how most unexplained failures happen and DOAs, especially with motherboards, CPU's, and memory. Statistically speaking, ESD accounts for nearly 40% of all electronic failures.

For all DIY'ers: Buy a cheap ESD wrist strap with alligator clips and clamp it to the case metal. Open any product ESD packaging with the strap on your wrist while leaning over the case, and the electronics will be at the same potential (voltage) as you and the case chassis. Much less chance for ESD failure.

I am submitting this review because I believe others considering this product should be prepared for the failures and, in my opinion, the testing that they should go through before using. To date, I have tested 7 drives and only have 2 working units!

WD is not doing as they should - to be responsible to their customers. This has cost me money and time. I really appreciate that, WD.
