    Great product but not discrete

    Great product but not discrete
    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.

    5.0 out of 5 stars WDEFZX-68AWUNO Died In 14 Months
    Reviewed in the United States on April 11, 2024
    Capacity: 4TBStyle: 128 MB CacheVerified Purchase
    Update: I finally was able to figure out how to get drive registered to get an RMA number. Once I figured this out everything else went smoothly. Then I got an app to check the HD again and it seems my problem was a previous power outage. Having never had this problem before, I wasn't expecting it. Anyway, I'm still a WD fanboy. Their return website is relatively painless once you figure it out. I rerated the HD to reflect these new developments.

    For WD40EFZX-68AWUNO... What a pain! Went to WD site to fill out warranty forms and it's not working right either.
    After a few crapped out hard drives from Seagate several years ago I went with WD. EVERY drive I have in service is now Western Digital.
    I put two of these in a Synology NAS and "drive 1" went kaput after 14 months. Buying another (68C6CNO) and hopefully WD will come through on the warranty if I can get it completed.
    WD warranty is most times pretty painless so I'm not really livid it's just that this eats up a couple of hours of the day when you're not set up to make returns. Oh well, things go wrong.

    5.0 out of 5 stars Replacement for a NAS drive going bad
    Reviewed in the United States on April 28, 2024
    Capacity: 4TBStyle: 256 MB CacheVerified Purchase
    Hard drives go bad. I've got a four drive configuration in Raid 10, and this is the first time I've had to test the 'self-rebuild' feature. Worked like a charm.

    As for the drive itself, the fan in the EX4100 is louder than the drives. It does what I want, which is protect my data without having to spend a bunch of time worrying about which drive has which backup version. Honestly, I don't even know most of the time when they're working.

    Highly recommend both WD, and also their RED drives.

    5.0 out of 5 stars Works Great with Synology
    Reviewed in the United States on April 5, 2024
    Capacity: 8TBStyle: 256 MB CacheVerified Purchase
    My level with servers is that of an absolute amateur. I don't need instantaneous speed, high uptime, or needing to handle high loads during a peak time. I use my NAS as a repository to stream movies on plex occasionally, store home photos and videos, and back up phone data across my family.

    While I cannot speak for those with more nuanced intricacies, I can highly recommend this for those at my level - to those who dabble in storing family data. The high storage capacity is perfect for RAID arrays, which has already helped once when an older drive failed due to other hardware difficulties. The rebuild was flawless. In addition, even when bulk information goes through the drives, the drives are never that loud. It's great for home use and is barely even noticeable.

    5/5 for surviving consistent uptime, good data storage for the price, and being low volume.

    5.0 out of 5 stars MyCloud Upgrade
    Reviewed in the United States on December 29, 2023
    Capacity: 10TBStyle: 256 MB CacheVerified Purchase
    I have a Western Digital MyCloud 2 Ex Ultra NAS on my home system. I got it with two 4Tb hard drives which were not enough capacity for my growing needs. I needed to upgrade this storage.

    I ordered these two 10Tb Red NAS drives which were delivered in a couple of weeks. I'd not done a NAS upgrade before so I was a bit nervous. However the process went extremely simply. Following the WD directions downloaded from their website I first opened the dashboard software and advanced to the point where it enabled upgrading the NAS. Then I opened the access door on the MyCloud 2, unscrewed the retaining bracket, and pulled the 4Tb drive #1 out of the NAS. I did NOT power off per the instructions. Dashboard detected this and asked me to wait for a couple of minutes. Soon it was ready for the new drive so I moved two screws and a handle from the 4Tb to the new 10Tb. The new drive dropped into the NAS and the rebuild process started without me doing anything. It took a few minutes for the Dashboard to update the progress indicator. It took about 9 hours to build the first 10Tb drive. When progress got to 50% the dashboard asked for the second 10Tb drive and the drive #2 spot on the NAS glowed red. It was a simple matter to pull the #2 4Tb drive, move the handle to the 10Tb, and insert the 10Tb into the NAS #2 slot. The rebuild started right up. In the morning when I woke up, the process had been completed and all 10Tb were on line. There was nothing else that I needed to do! I was amazed that the process went this simply. Kudos to Western Digital!!!

    I've been a long time purchaser of WD drives. I've owned many. This drive uses older technology, but still was a worthy upgrade for my QNAP NAS. I have a 2 slot in Raid. I had 2- 4 TB drives WD reds. I pulled one drive to test about 3 month ago, and the NAS did not recover well... The one drive had read errors, so I decided it was time to upgrade. It was a total cluster F* to upgrade, but, I now have more than doubled my NAS space, so it was overall worth it.

    I took 1 star off as the old WD 4 TB RED drives had a disk failure after 3 year on a rarely used NAS, the drive had only recorded 30 hours of Write time. Overall I'm happy with the red drives, but if these new drive don't last 5 years or more, I won't buy WD RED anymore.

    These are not cheap. They are designed for heavy use in NAS (Network-Attached Storage) in large data centers. Two years ago, I bought four of exactly the same model for my small 4-bay NAS, and all four have performed flawlessly. I bought this to have a replacement drive when one of these fails--note, all hard drives eventually fail.

    5.0 out of 5 stars Excellent backup NAS drives

    I’ve been a long time fan of Western Digital hard drives and have never really had any luck with seagate drives. I ordered 4 of these to replace my 8 year old Western digital 4TB NAS drives to expand my exploding digital footprint. They are still running in perfect working order. I must commend amazon on the packaging and delivery. I was a bit concerned after reading some older reviews. As you can see from the pictures, they were securely packaged up well.

    The drives themselves have passed extensive read/write tests without so much as a hiccup. One thing to note however, is that this hard drive tends to be a little nosier. More than likely due to additional platters compared to the 4TB variant. Also important to clarify that this review is for the CMR version.

    HDDs are starting to get expensive again. We picked this up on sale to expand our Plex server size. No problem, easy install and quick format.

    5.0 out of 5 stars Excellent NAS Box Drives

    I've used WD drives for years, and when I bought an AUSTOR NAS box, these were the ideal drives for it. I've had them for a couple of years now in the Box, and have had 0 issues with them. These drives are hard to come by, after the WD fiasco with NAS box drive types a few years back, but they are still the gold standard as far as I'm concerned. Read and write access through a 2.5GB connection is fast, even in Raid10.
    Overall, these drives are great for NAS and highly recommended if you can find them!

    I already bought a the same disk 3 years ago and it still going strong, performance is rock solid, so I wanted to go with the same disk again. The disk was tested fully in single mode and raid configuration and it meets my expectation fully

    Pro:
    - CMR disk so its suitable for NAS
    - Reliable for long time usage
    - Sequential write performance between 200-83MB/s depending on the region being written (The farther away from the inside of the disk platters you go, the higher the velocity of the head thus resulting in faster speed)

    Con:
    - tends to get hot so need proper ventilation
    - 5700 rpm compared to the red prod wich is 7200
    - warranty is only 3 years for the red pro compared to 5 years for the Red pro
