4TB My Book Desktop External Hard Drive - USB 3.0 - WDBFJK0040HBK-NESN,Black

I purchased this drive largely based upon a specific need for a USB 3.0 product with 4TB of storage. I've owned many WD internal and external HD products over time and have not had any drive failures to date over many years. I purchased this drive specifically as a backup storage drive attached to a Synology 1813+ NAS unit. This required a reformat to EXT4 as the drive comes natively formated in NTFS. The Synology NAS schedules backup to this drive of selected folder shares using the "Time Backup" software available from Synology. I'm not utilizing any of the software included from WD with this drive (backup, cloud, etc.) as the Synology NAS has its own software for each of these purposes. The drive itself is similar in size to other My Book drives. The plastic casing is certainly not as nice as the aluminum finish on the WD My Book drives that I have for my Macs, but it is similar to the black of the Synology unit and overall looks good. The power adapter is reasonably sized (not a brick), and the unit comes with a USB 3.0 cord for use with its single USB 3.0/2.0 port. WD provides a 2-year warranty with this product. There are cheaper drives with similar specs available from other companies. However, having had drive failures with Seagate over the years, I'm unwilling to take chances with other options. It's important to backup your valued files, and WD drives have played a major role in my backup solutions over time. If I have issues with this drive, I'll update my review. This seems to be another winner from WD! Edit/Addendum: Following my review, another Amazon user asked me an excellent question, "Does the USB connection to the drive feel flimsy?" This is a very appropriate question given concerns raised with the prior generation of this same My Book device. While I don't own the previous My Book version in question, I did check the USB connector on my device. The supplied USB 3.0 cable seems to be stable in its connection to the rear port of the My Book case. I can't physically make it move horizontally or vertically with any significance - unless I were to apply excessive force. Modest attempts at movement of the USB cable did not disrupt the connection. I don't plan to move this My Book from one place to another (it's connected to my NAS), so I suppose that I won't be able to comment well on wear-and-tear issues with respect to the USB connector. Other My Book devices that I own are the Mac Firewire/USB 2.0 version. Those have never struck me as flimsy. Update 1/18/14: Since writing my original review, I've purchased a 2nd unit which I reformatted for Mac OS X and use for "time machine" backup. Both drives are functioning well and have had no issues. I'm still very pleased with the quality and function of the drives. Reading through a number of the questions regarding this drive, it's clear that the term "cloud backup" as assigned by WD to this drive is a bit of a marketing stretch. As has been noted by others, the "cloud backup" option is not intrinsic to the drive, but an add-on service provided by Dropbox and facilitated by WD software that a user may choose to run on an attached computer (I don't personally use or recommend that others use WD software). These drives are nothing more than a WD drive, in an enclosure, with a single USB 3.0 connection. If you are looking for "cloud" capability, other product options do exist. I do hope that WD changes its description of drives such as this in future marketing.

I was intrigued when I saw this "6TB external hard drive" selling for $183 when the cheapest "bare" 6TB hard drive that Amazon sells is (as I write this) for $223, the Caviar Green model. How/why could this external drive, with its case, USB 3.0 interface, a power supply (12V @ 1.5A), and a USB 3.0 cable, sell for $40 less than a bare hard drive? Do these additional pieces of the assembly cost negative $40? It makes you think that if someone somewhere was selling whatever 6TB drive is inside this thing as a "bare drive," it should be selling for about $150. Wouldn't you think that? I took a gamble and ordered one on a Saturday night. This afternoon, Tuesday, 3 days after placing the order, it arrived at my doorstep, with an "Amazon Prime" sticker on it. I was pleasantly surprised, since I'm not an Amazon Prime customer. But hey, I'll take it. The first thing I did was to connect the drive to my Mac via one of my USB 2.0 cables with a micro-USB plug, since my Mac does not have a USB 3.0 interface. I should also say that I am running a very old Mac OS (10.6.8) since I remain suspicious of the later Mac OSes. The hard drive light blinked a couple of times, and within a few short seconds, the drive mounted. I launched Disk Utility to inspect the drive, and to no surprise, it shows as the Mac interpretation of FAT32. Since I care about neither PC formatting nor the included Acronis True Image utility, I erased the drive and formatted it as a Mac OS Extended-Journaled drive (standard Mac format). The drive spun away for about 30 seconds, and just like that the drive was reformatted and mounted on my desktop. I then knew that the drive was alive and well. I wasn't going to have to return it for any defects, so it was now time to break it apart, meaning I now own it! I did a quick internet searching about how to break apart a My Book hard drive and found many videos. All pointed out that there are snaps, not screws, that must be released, and getting them to release means that the snaps WILL break. I.e., if you're going to take the case apart, do not expect to be able to return it! It turns out there are 2 snaps on each side, at the back. The placement of the snaps is not symmetrical, as they are offset from one another. Nevertheless, prying with a couple of small blade screwdrivesr broke the four snaps, allowing the two halves to slide apart and separate. Sliding the two halves apart is easy. There is a little USB 3.0 interface daughter board that plugs into the standard ATA drive interface and is held in place with one screw, simple to remove. There are four rubber shock mounts that require a T-10 Torx screwdriver to remove (or you might be able to use a thin blade screwdriver ... maybe). And with that, you have your jail-broken hard drive. And what did I find? I'll be darned, but there sits a Western Digital Caviar Green drive, model WD60EZRX, 64MB cache. The label on this drive is exactly the same label you'll find if you go out and buy this bare drive on Amazon for ... $40 MORE! There is no difference whatsoever between the drive in my hands and the one shown on the Amazon page displaying the WD60EZRX Caviar Green 6TB drive. I've been contemplating buying a few 6TB drives for a while but have been put off by the price of the bare drive. If you're willing to tear apart the enclosure of this external drive and throw away everything but the drive, you can save $40/drive over the cost of a bare drive. Go figure! I found my discounted 6TB bare hard drive. I'm putting in my order for a few more tonight! UPDATE1: More units bought, and they're all Caviar Green drives. And the deal is often $52 cheaper than buying the raw drive! ($223 - $171 = $52). I've also found that when tearing apart the My Drive to get to the bare drive, it's worthwhile saving the USB3.0-to-SATA interface card and the power supply. The two make a great simple adapter to interface between any SATA drive and your computer! I remain mystified as to why the bare drive is so much more expensive than the My Drive, which is loaded with a whole lot more $tuff around it than the bare drive. UPDATE2: More drives bought, and now they are all Caviar Blue drives! Thus, there is no consistency as to what type of drive WD will install inside their enclosures. However, no perceptible change in performance, noise, or power, have been observed with this change.

I bought this specifically to use it as an external storage option for my Xbox One, which was down to less than 10% available when they released the update that allowed external storage in early June 2014. If you are considering this drive as an external drive for your Xbox One system, I can assure you it handles the task quite nicely! When I plugged the drive into an available USB 3.0 slot on the back of the Xbox One, the Xbox One immediately recognized it as an external storage device, and asked if I would like to format the drive. Formatting was very straight forward and very quick. The Xbox One OS also gives you the opportunity to name the drive, which I kept at the default "External" so you can tell internal storage from external storage. Another nice feature is that the Xbox One gives you the option to always install new content to the external drive until it is full. If you select this option, then anything that is installed from this point forward will be installed to the external drive, as long as it is connected. It's a great drive, very quiet, very quick, and I have no issues playing games off of it rather than the internal drive. Again, if you are considering this for an external storage option for your Xbox One, do it!

Delivery was prompt. The hdd worked as expected.

Works beautifully on my Xbox One. Visible difference in loading times.

この製品を2015年10月に購入し、Macbook Pro13 Mid2012にて使用していましたが、8ヶ月ほどで急に接続が途絶えたりとアクセスが不安定になってきました。 そこで修理を依頼したところ、「良品との交換」となり、アメリカからそれが送られてきました。 その後しばらくは問題なく使用出来ていましたが、交換から2年10ヶ月ほど経過した2019年4月に、突然アクセス不能となってしまいました。 市販のディスクユーティリティー等を試してみても認識できず、内部に保存されてあるデータは結局取り出すことができませんでした。 異音やアクセス不安定などの症状があれば新しいHDに交換するのが常識ですが、そのような前触れ無しにいきなりアクセス不能となってしまうようではWD社のHDを再び使用する気にはなれません。

I confess to not having spiked it in via the usb 3.0 yet, however the unit appears 100% and should perform as robustly and reliably as all my other WD products, NONE OF WHICH (Western Digital only) I HAVE EVER EXPERIENCED A PROBLEM WITH!! I can only say this about Western Digital products - others hard drive manufacturers like Samsung hard drive division (since bought by Seagate, which subsequently was then bought by Western Digital) have in past proved dismally unreliable, and customer service was lacking in my several experiences with these brands, as well. G-Tech, now owned also by WD, proved the worst ever experience, worse even that the dismal Samsung and the dismal Seagate. And it wasn't even about the products, which are ok. It was the executive attitude there at G Tech in California toward us global consumers (distrustful, arrogant, smug and self-satisfied, and blatantly outwardly hostile) that gave me the utter creeps, as I experienced a certain executive at that company (G Tech) who was downright sleazy and paranoid when I dealt with her on a matter related to their product line - I own 4 G Techs, but would never bother with that brand no matter who owns them now, as the company's core team as represented by this key marketing employee has demonstrated some lousy attitude toward customers, I discovered. Lady Marketing exec at G Tech, if you read this you know who you are and you simply suck as a brand builder and aren't half as smart as you think you are, you smug wonk. I will never forget that B%^$#& executive at G-tech and I hope her bosses threw her to the curb by now like yesterday's trash, for she is indeed a true brand liability. She knew so little about the technology she was representing as a Marketing head, and it was via her that I realized how far we consumers are being conned on pricing for these basic peripheral, and how little we are respected and valued by the executive team that gets paid the nice salaries there at G Tech. Get over yourself lady Marketing head at G Tech, you know who you are and yer shi^ ain't that special. She reminds me of the scumbag cd music execs at the big name music studios from an earlier era who were disdainful of both consumers and the recording artists as well – just give them their go^da8n money and everyone be damned... G Tech execs are just not likeable people, I discovered. They have issues. Moving on... WD is the reliability leader in the external hard drive realm. So assuming this WD unit performs as it should (which I have no doubt it will), I will comment on the speed of the Amazon transaction itself... It was expedited with great efficiency and precision. Yet another win for Joe Consumer, as this unit was at a "great" price point. Now if this general product category would only begin to lower its prices and keep them there, I would be thrilled. As it is, one has to be patient until such a deal as this price point makes its appearance. I feel these hard drives are generally selling here in Canada for more than is necessary for WD and the others to turn a profit, and I wish they would rethink their pricing strategy to enable consumers to avail themselves more of this technology with less concern for the high prices. More units sold (greater economy of scale) will net WD great profits and will benefit consumers simultaneously, as opposed to socking it to us with these (on average) $250-$300 per 6TB drive prices... this reminds me of the way the cd was used to exploit / extort the western consumer into parting with more cash than was necessary to purchase a simple prerecorded cd. The vinyl album pricing (moderate expense) soon enough gave way to the duplicitous collusive industry pricing of the cd industry, which became something of a rip-off. With external hard drives, they don't need to go for the kill price to succeed, but these consolidated hard drive manufacturers (and WD owns quite a few recognized hard drive brands under its umbrella). In my opinion, the industry jacked hard drive prices some years ago complaining their manufacturing infrastructure in Thailand was compromised due to destructive typhoon. OK, boys that ship has sailed long ago and you have your Porsches parked in your garages and your new home renos done now, so lay off on the overheated prices for these pretty basic pieces of modern technology that will in some few years essentially be obsolete tech. OK I'm done now. But WD does make a great hard drive regardless, so buy WD as they have earned this loyalty.

El precio está muy bien. EL paquete tardo un poco en llegar pero sin ningún problema. Lo único malo es que como casi todos los WD, su diseño de plástico puede llegar a hacerlo un producto fragil. Es importante saber que si planeas estarlo moviendo de un lugar a otro, conviene comprar un disco portátil que ademas no requiera un eliminador de corriente como este. Fuera de eso, el producto es bueno, con mucha capacidad y velocidad, es USB 3.0
