Customer Ratings & Reviews

You see this? You want this. You know why? It's a Western Digital, start there. It's a Red Plus = Fast, reliable, NAS. It's the right price. AND It's the actual best model offered... It's the WD40EFPX model, meaning... - It's a CMR drive (not the cheaper, less reliable and slower SMR drive). - It has a 256mb buffer (not 128mb) - It's a PLUS series... Faster than Red, slower than Pro, still super fast for an HDD. - It's built to last... for servers, RAID and home use. Oh, and it's almost the same price as a Blue (entry level). Bottom line, for backup and daily access... GET THIS!!!

I picked up the 4TB model (WD40EFPX) for a small Synology setup running RAID 1, and after several months of use, there's genuinely not much to complain about. It's a CMR (Conventional Magnetic Recording) drive, which matters. WD caught flak a few years back for quietly shipping SMR drives under the Red label, but the Red Plus line uses CMR across the board. That means better sustained write performance and more predictable behavior in RAID rebuilds, which is exactly what you want in a NAS.

I recently purchased 4 of these to replace the old drives in my 7 yr. old EX4100 NAS configured to RAID 5. I hope the new ones hold up just as well. Had issues backing up loads of data and then uploading. I believe the bugs were not in the drives but issues with the other devices and wifi. WD support was excellent and attentive. Take pics of the serial numbers before installing.

I bought the WD Red Plus 4TB for my home NAS running TrueNAS, and it’s been rock solid so far. The drive runs quietly, stays cool, and has been working 24/7 without any issues. I’m using it in a RAID setup, and the performance is great — good read/write speeds and all SMART values are healthy. If you’re building a home server or upgrading storage, this is a solid choice. I’m already planning to grab another one to expand my array

I had a WD EX2 NAS drive with one slot filled with a 4tb WD Red Drive. Added this one to give me twice the storage for backup. It was easy to format using the EX2 software. Works great, as long as you use two drives that are the same size.

More space for my video editing, Love the Red Plus from WDC pretty reliable bought four durning the pandemic, planning to build small NAS server for home office.

i have thousands of photo and many GB of files ,, that i need lots of space ,, so this fits in my dell 8940 slot as a just perfect just fit .. however, i am always wary of using very large disks to store TB of files and lose if it breaks ,, 4TB is just about the max size i will use .. so far with 1.5TB moved on it and working for the last 2 weeks .plus bought this on BB sale. and then got a lower price next day when it went on sale again with BB price match .. for a great deal from BestBuy

New drive with good write/read speed for the HDD. A perfect replacement for my old drive, using it with the external adapter. It is sad that a bigger drive was not in the store at that moment.

Always pleased with these WD drives. Most reliable drive that I use

Why do I keep stopping when I use my Seagate hard drive? So I use a Western Digital hard drive. unshakable trust

WD Red drives work well. They last a long time and have solid performance. Years of worry free service. Easy to install.

I'm very happy with the product and used it with another WD Red Plus 4TB hard drive in my NAS as a RAID in case if one drive fails, I can just put another one in and what is on my other WD drive will replicate on the new one. It's the best way to save all my family pictures and other important files.

I use 5 of these in my Synology for hosting media. They're perfect for media streaming and are regarded for their reliability. Have been going 2 years strong with no issues so far, can't find anything to complain about.

These are awesome drives. Solid performance, great reliability so far (been almost 2 years with no issues on all three that I bought), and good value (if you can get them on sale). I just use them in my PC, and they're surprisingly quiet. I highly recommend doing regular backups regardless of how good a drive seems on paper. But other than that I highly recommend these drives.

Great for my nas. Own multiple for a few years no issues. Got another to expand storage

Purchased from Best Buy and using it in my NAS; the SanDisk 4TB HDD delivers consistent performance, runs quietly, and has proven to be reliable for continuous use.

The WD Red Plus series hard drives for NAS are nice and reliable. I noticed that they are not as loud as the Seagate IronWolf hard drives. The price is good as well.

Had this running in a Ugreen NAS for a while now and works great. Lots of storage and good transfer speeds. Looking to get a second one with more storage now.

Good drive. Nothing exceptional, decent hard drive. I have been using a hard drive for a while now and I must say that it's a decent one. Although it's not that fast, it's reliable and gets the job done. It's not an enterprise-class hard drive, but for the money, it's not a bad choice. Overall, I'm satisfied with my purchase."

This is my umpteenth purchase of a WD drive. Never had a problem with any of them. This was an upgrade for a raid drive, same brand WD Red, which I purchased almost 7-8 years ago. Those drives are still running perfectly, however, they were only 2TB. I will use the old drives until they die, however I wont keep critical files on them. Maybe use as a back up of a back up of a back up. I do tend to be a digital hoarder, and maybe putting files i dont really need on aging equipment my give me the pust to let go once the device fails :). But i do follow the 3-2-1 rule for backing up my systems. I also do a "hardware refresher" every 5-7 years, just to take advantage of the new technology and refresh the lifecycle of my hardware especially those that store my data.
