Western Digital 4TB WD Red Plus NAS Internal Hard Drive HDD - 5400 RPM, SATA 6 Gb/s, CMR, 256 MB Cache, 3.5" -WD40EFPX

This hard drive works well and was easy to install. It was recognized right away and is a good option for extra storage or a NAS setup. It runs quietly, has plenty of space, and feels like a reliable drive for backups and everyday file storage.

Have been using Western Digital drives in my home NAS for many years. They’re reliable and of course don’t last forever but I do get a few years use before they finally die. Fortunately, a RAID configuration keeps a dead drive from turning into a disaster whereas I can order a replacement in a timely manner.

I have always used the WD Red drives in my servers and NAS units since they brought them out...this is going all the way back to the WHS 2011. They are good drives, economically priced and last for ever in the right conditions. I recently migrated over from a WHS box to a WD server, and these were the natural choice for it. They were recognized immediately and set up quickly in the WD server. As I monitor the health, there have been no critical issues for the drives in the 7 months they've been in the WD server. I recently added two more 4TB drives in the Raid 1 function, which now gives me 8TB of secure and stable storage. This matches the level of performance that my original 4- 1TB Red drives I had in my WHS 2011 server, which to this day, is still showing as healthy in the pooled drive array as reported in the SMART monitoring.

Excellent price and quikc delivery. Exactly what I needed.

Perfect

I built a small TrueNAS box with four WD Red Plus 4TB drives. Within the first year, one drive began throwing SMART errors. Because past RMAs with WD had taken a month or more, I bought a fifth drive out-of-pocket to keep the NAS healthy while I waited on support. Things went downhill from there. Eventually two drives started failing around the same time—the point where this whole troubleshooting saga began. I tried to use a “white-label” WD replacement they’d sent me the year before (kept sealed as a cold spare), but it was dead on arrival. That pushed me to buy a sixth drive to stay afloat and RMA the DOA unit. When the RMA replacement finally arrived, it lasted about two weeks before it started logging read errors and then disappeared entirely from the system. I opened another RMA. As of now, I’ve purchased or received a total of 8 WD Red Plus drives and 5 of them have failed in some way (including the DOA spare and the two-week wonder). I’m still waiting on two outstanding RMA replacements, and I’ve just added another drive to the RMA queue. This round, I cut my losses and bought a Seagate IronWolf Pro 4TB to replace the latest failure. What went well When they work, performance and acoustics are fine for a home NAS. WD does honor RMAs. What didn’t Reliability (for me) was poor: 5/8 drives failed within ~2 years. RMA speed: turnarounds often stretched to a month or more. Confidence hit: receiving a DOA replacement and a replacement that died in ~2 weeks eroded trust. Verdict Based on my experience, I can’t recommend WD Red Plus 4TB drives. The failure rate, DOA spare, and slow RMA cycle created too much risk for my data and too much hassle for me. I’ve moved to Seagate IronWolf Pro to restore some confidence in the array. Tips I learned the hard way Test every spare immediately (SMART short + long) so you can RMA within the seller’s return window. Monitor SMART weekly and schedule ZFS scrubs; act on “pending sector” or read-failure alerts right away. Keep a known-good spare on hand to minimize downtime while RMAs drag on. Your mileage may vary, but this was my honest, first-hand experience with WD Red Plus 4TBs.

Picked this up as an external drive for storing images and model files, works great.. no performace issues. Only ever had one WD drive fail in the last 30+ years .. totally my goto when buying drives.

Quality product but it was not shipped in a plain box that hid what it was. It was shipped as seen in the pics with a shipping label placed on the retail box, meaning anyone who drove by my house could see a new hard drive sitting on my porch until I came home from work to bring it inside and anyone who encountered it during shipping knew exactly what it was. Considering I've had drives disappear during shipping before I was kind of surprised this was shipped in this manner. Other than that it was as advertised and works as expected as a replacement for a failed drive in my NAS.

Good

Arrive well and fast. Performance wise is also is typically of WD quality.

Ich habe dies Festplatte für meinen WD NAS Speicher gekauft, weil die originale immer auf Störung ging. Am Anfang war ich skeptisch ob diese Platte passt und auch funktioniert alleine schon weil sie ja nicht gerade billig ist. Nun ist sie schon einige Monate im Dienst und funktioniert einwandfrei. Es gab bisher keine größere Probleme. Sie ist auch sehr leise, so das man kaum etwas hört, wenn Daten drauf gespielt werden. (Bei normalen Umgebungslautstärke. Wenn natürlich alles leise ist z.b. Nachts) hört man sie natürlich schon etwas intensiver. Da sie aber bei uns im Treppenhaus zentral steht, ist das für uns nichts negatives. Würden wir auch jederzeit wieder kaufen bei Ausfall oder wenn wir unseren Speicher vergrößern möchten.

Disco muy silencioso. Buena velocidad.

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.
