This product lasted all of 45 minutes. It was plugged into a Mac, formatted, and then used to back up customer and project data. I then plugged it into a second device to archive more data only for the device to start clicking and whirring its inevitable demise. Try as I might, it wouldn't start again. I am now left with a $280 dollar brick that I cannot return to the seller for repairs or a replacement as it contains customer data that cannot be shared for legal reasons. And to be clear, there is nothing wrong with my devices, or the USB ports I am using. This is not the first time a WD product has failed on me. But I can say with confidence it is the very last time I buy a WD product.

As usual with WD drives, the hardware is solid. I just hate the archaic lock software on PC. You have no easy way to toggle different computers to auto unlock without password. It's been YEARS and still doesn't work right. You have to remove the password and can only autounlock 1 computer, usually. It should be a simple toggle after typing in the password, and then possible ask for the password again or some second measure per computer. The software needs to be updated. I NEVER buy a WD drive without hardware encryption, but the software behind it lacks, always. WD, HIRE some good people to refresh this and make more options and make it user friendly.

I have an embarrassingly large number of backup drives. Part of it is as a commercial photographer it’s a necessity – at last count I have something approaching a quarter of a million photos in my lifetime file. The other reason is I’ve learned the hard way to back up all of my work, then back it up again, and then make sure to make another backup to take off premises for safety. This is my third WD MyBook. There’s no real reason this product exists, there are cheaper ways to get a backup drive and use it with a computer, but these are convenient, dependable and reasonably priced. I bought this one to do a mega consolidation of everything I have on many different media, except for my photography. WHAT I LIKE The form factor is simple, just a plastic monolith case ... MoreI have an embarrassingly large number of backup drives.

There’s no real reason this product exists, there are cheaper ways to get a backup drive and use it with a computer, but these are convenient, dependable and reasonably priced. I bought this one to do a mega consolidation of everything I have on many different media, except for my photography. WHAT I LIKE The form factor is simple, just a plastic monolith case that can be used either horizontal or vertical. I choose to use it vertical to take up a minimal amount of desk space. I like to keep it right there in front of me as a visual reminder to be sure to do a daily backup. IMPROVEMENTS WD seems to have this product line down pat, it’s old technology that has proven itself and there’s not a lot they can do to make it better. The most positive thing I can say about it is that they wisely don’t load it with a lot of useless bloatware to try to make it look more important to you. There are just two relatively small apps, one for PC and one for Mac for those who like to use backup software. Both files are easily deleted in seconds if you don’t want them. I choose not to use automated backup software, I simply copy entire files and folders from one drive to another so there’s no guessing where they are or what they’re named. OPINION I find it unfortunate that here we are deep into the twenty-first century and there are still reviews about how noisy or slow these drives are. Your’re not saying anything new by bringing that up, yes they are, if that bothers you don’t buy a hard drive with a spinning platter. There are those who will say, and count me in on that, mechanical hard drives continue to be used because they are the safest media we can use, the chances of recovering a corrupt or lost data file is highest with these than any other media. The method being used to use a moving recording head back and forth on a revolving disk is going to cause some noise and it’s also going to be a bit on the slow side. I find that the speed is only a factor when I first get a drive and I’m copying huge amounts of data to it, and yes that can take hours. After that most backups are cumulative and how long they take has never been an issue for me. And like I said, I keep my WD right in front of me on my desk and they’ve reduced the vibration and noise to the point that it is almost imperceptible. Because this product does exactly what I expect it to do and because of my positive experience with the MyBook product line I believe this earns a full five stars.
Easy to plug in and operate. Has it's own ac power source, so no drain on computer. However, I didn't realize, that every time I did a back up, it duplicated data , rather than only saving new data. Bummer. The external HDD filled up faster than expected. Then, one day, in the middle of a back up, it just stopped working. I had a chat with a tech on the WD website who suggested a new USB cord. That didn't help. Then I tried The scan diagnostics software that came with the HDD. It failed the first scan which meant the HDD was garbage. I checked in disc management, and the entire HDD disc was full. After speaking with a tech at a computer store, he suggested this was most likely the reason the HDD failed. I plan on checking to be sure that the next external HDD I buy ... MoreEasy to plug in and operate. Has it's own ac power source, so no drain on computer.

I just wanted to drop a note about the Western Digital MyBook 4 TB drive. I’m going to purchase a new MyBook, even though my 13 yr old one is still going strong. The drive has backed up our old PC and our IMac. I have never had any issues with this drive. It does what it’s supposed to do. It sits next to the IMac, quietly backing up our data. I looked at other brands, but Western Digital did not let us down. I will stick with the brand. I hope the new one lasts just as long!
I read a lot of reviews about this particular hard drive and felt comfortable about my purchase. I am REALLY starting to regret it, though. This hard drive is incredibly slow. It seems like it goes to sleep. When I click to go into it, for some reason it takes several seconds for it to react. And even when I do get in, if I click another folder, it also takes a few seconds to react. I use this for my business (sometimes with clients right next to me), and it is embarassing to have to sit there and wait for this thing to react. :-/
The drive formatted to 12.79TB using ext4 on Ubuntu 20.04 LTS. Seems to run cool and extremely quiet. The only way I can tell it is working is by putting my fingers on top of it and feeling for vibrations. UPDATE 1a: OCT 26, 2020 The drive did get hot after months of use inside the original enclosure. It reached a temperature of 56C/132F. So that should be a concern. It runs 29C/84F inside the Synology 220J with active fan cooling. The room it was in was air-conditioned and no more than 75F ambient room temperature. Both drives are WDC WD140EDFZ-11A0VA0 14000.5GB Firmware 81.00A81 5400 RPM 512 MB Cache (HC530 are rated at 7200 RPM so these drives are throttled down to a lower RPM or at least one is - idk) HGST HC530 family drives with TDMR UPDATE 1b: OCT 26, 2020 I ... MoreThe drive formatted to 12.79TB using ext4 on Ubuntu 20.04 LTS.

I wanted a low power solution to keeping movie files available for Plex and Home Essentials Direct had a Prime Day sale on an entry-level Synology DS220J NAS. The two Nvidia Shield Pro 2019 will handle any heavy transcoding (if any) because the NAS is not designed with Plex transcoding in mind. My second drive came in a different color box too so I initially panicked. But after running CrystalDisk Info and Speedtest, I was relieved that both boxes had the same exact drive inside the hard plastic enclosure. So I hope this serves as a heads up for anyone shucking these drives too. Rest assured they are the same drives with the same exact firmware. The first was purchased in June of 2020, the second in August of 2020. Four months apart. Keep that in mind as we head into 2021 and later. I did get different benchmark tests but I am hoping that it was due to having four months of data (7 TB) on the original drive and perhaps CrystalDisk performed its benchmarks from vastly different cylinders on each drive. As you can see from the included screengrab, the model numbers are identical. The DS220J also reported the same under DSM 6.2. I will have them set up as SHR mirroring in the NAS. I wish I could have done the benchmark test with two clean drives but I would need a third 14TB drive which would make it a bit beyond my means at this moment. UPDATE 1c: OCT 27, 2020 (added one additional picture of Storage Manager, Synology's NAS app) I have both drives inside my Synology DS220j running Synology's parity consistency check for at least 30 hours non-stop. Both drives run significantly cooler on the Synology NAS than the WD plastic enclosures. In the WD plastic enclosure, they ran at 54-56c while on the NAS, they run 30c-33c. Average about 20 degrees hotter centrigrade in the WD factory enclosure. I wonder if earlier failures I had with other WD USB drives in the past could be attributed to them running hotter than normal. Even if you don't need the advanced features of a NAS, I would recommend a lower-end less expensive model like the DS200j just to keep the drives running cooler and of course for its data redundancy protection. I will continue to update for at least one year. If the nas works out for me really well for the next twelve months, I'll upgrade to a four bay unit to use some of the more advanced raid implementations.
My Book Desktop 4TB HDD Certified Refurbished from Western Digital store works very well. Shipping was fast. Goes to sleep a bit too often and is sometimes slow to wake, but I found an application that keeps external HDDs awake and spinning and thank the maker of that software for his work on it and his sharing it. I don't use the software that comes with the My Book but it's there if you want to use it. It is quieter than other desktop hard drive disks. I've seen this model that people one person said has a 2.5" disk and more that say it has a 3.5" disk. I haven't opened it to see so as not to break the warranty. I guess I'll weigh it and a confirmed 3.5" external HDD. Good capacity HDD for general photo enthusiasts that use high resolution cameras.
i bought the 18tb one. it works very well for the price.it does have some issues, but they're all mitigated by the relatively inexpensive price and huge storage size.the main issue is a 'clicking' noise that occurs every few seconds. at first i thought the unit was defective, but after some research it seems it's a normal noise for this hdd.this hdd transfers large files (ie raw video) decently fast for an hdd - averaging about 170-180MB/s.it still uses a usb3 port which is significantly less convenient than a usb-c port, but that does not affect performance at all.overall, for the price and storage size it is a great external hdd!
