MTBF is supposed to be 1 million hours, but I have had two drives in the past 4 months start showing I/O errors and failing SMART Tests. They've only been running for for about 33000 hours.I went out of my way and paid more for Reds since this is supposed to be better for NAS use, but my Blues and Greens in my other stations have similar or longer run times with no issues.

Although these drive are labeled NASware 3.0 I found out after I received the drives that they use SMR technology. I intended to use the drives to increase the storage on my ReadyNAS. but in speaking to a Netgear representative he recommended against using SMR technology because they had found them troublesome for writing large files or many files continuously, and especially on RAID sync, scrub, and balance. I researched the drives further and found this was indeed the case. By this time I had already hot swapped one of the drives I'd purchased in anticipation of increasing the storage and upgrading the OS. As part of the upgrade the raid did a resync. The resync took 5 days to complete.

In the past my resyncs have completed overnight so I find 5 days unacceptable. In short I don't have confidence in the reliability of SMR drives for my NAS. I requested an RMA be generated to exchange the drives I purchased for the CMR drives I thought I was getting but it's been 2 weeks and I'm still waiting.

Great drive that lasts. I put in my second WD NAS because my other one performs so well. I only added this one so I could separate different data. My original Red Drives never have failed.

All 3 of these drives that I have purchased (within 2 years) have failed. The last "operating" drive only reads at about 5 MB/s, which is sad. They all make a "chirping" sound at random, which is the motor powering up and down. Not buying another one of these drives. Not worth it. 3 of 3 basically bad hard drives. I would only rate these as fair because the motors have not completely given up, but the chirping and slow reads are only getting worse with time.
Hard to rate a new drive. Purchased these two drives because I had one fail, while still under warranty, and I think I'm talking to a chatbox, who won't send me an RMA as promised over a month ago. But the failed drive is a replacement for a MyCloud Ultra II device that failed while still under warranty, which was a replacement for an out of warranty MyCloud device that lasted for about five years.
I use(d) WD for a very long time and relied on the fact I never had issues with any of these drives. Until I purchased WD Red 6T for a NAS. I learned WD is very unclear about the fact this drive should not even be used for a NAS (unless maybe single drive but one cannot call that a real NAS). Anyone who has some experience with NAS will put those in RAID mode and this drive is a nightmare when used in RAID.
Purchased a My Cloud EX2 Ultra with two 4 TB Red Drives in August 2019; Drive 1 degraded in June 2020, replaced with a new 4 TB Red Drive, connected to an UPS; upgraded to OS5; in September, 2021, the power led of my My Cloud EX2 Ultra turned red and Dashboard showed that my disk degraded, replaced Drive 1 with the RMA replacement received in 2020; in 3 weeks, the Disk 1 led of my My Cloud EX2 Ultra turned red and Dashboard showed that Disk 1 was bad. Don't know if the enclosure caused the problem.
I purchased the Red 6TB drive as a replacement drive for by 5-bay Drobo connected to our home Mac server, and used for storing Time Machine backups for our 5 computers. The Drobo has only WD Red drives purchased over the past years, gradually swapping in larger Red drives as old ones fail or I needed increased storage space. This is probably at least the 10th Red drive I have swapped in to our Drobo. As soon as I swapped in this drive I noticed it wasn't as usual. The Drobo would unmount and re-mount repeatedly during the RAID rebuild phase. When it was done rebuilding I tested it out by running a Time Machine backup, which should do an incremental change to a sparse bundle file. I noticed that the entire sparsebundle file (1.7TB) was reduced to zero bytes and the ... MoreI purchased the Red 6TB drive as a replacement drive for by 5-bay Drobo connected to our home Mac server, and used for storing Time Machine backups for our 5 computers.

When it was done rebuilding I tested it out by running a Time Machine backup, which should do an incremental change to a sparse bundle file. I noticed that the entire sparsebundle file (1.7TB) was reduced to zero bytes and the backup software prompted to perform a "first backup", i.e. the historical changes were lost. I then noticed that this was the case also for all backup sets for the four other computers in our home. I now realize that the Red drive I purchased uses SMR instead of CMR and that these new Red drives don't appear to be suitable at all for our purpose. I can see that this information is on the website but how can WD make such a significant change to a product line and keep its name? Apparently, the Red is now named Red Plus but that was not obvious at all. I cannot believe how the good people at WD could allow this to happen. This is probably a decent standalone drive but it should not have been allowed to drag the Red (NAS/RAID) product line in the dirt. I am devastated, sad and angry with myself for trusting the product name so deeply that I didn't do research. And I am angry with WD for betraying that trust.
WD40EFAX drive is a great drive for 24x7 operation in NAS systems. I have owned a WD MyCloud EX4100 (4-bay) NAS for about 5 years now and have only had one drive degrade to the point I needed to replace one disk. After replacing the faulty drive the NAS rebuilt the RAID configuration and I never lost any data. I subsequently purchased a spare WD40EFAX drive in case of another failure.I highly recommend these drive. They are extremely reliable in constant operations.
I bought two of these to put in a dual-drive NAS. They work great for my needs. I only use to NAS for backup purposes, not as primary storage. Otherwise I would go with the WD Red Plus because it uses CMR write technology rather than SMR like the WD Red. You can google CMR and SMR for more info on why that makes a difference.I ordered these directly from Western Digital and the shipping was super fast.
