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 desertcart 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. Review: How to save $40 on a 6TB WD Caviar Green hard drive - I was intrigued when I saw this "6TB external hard drive" selling for $183 when the cheapest "bare" 6TB hard drive that desertcart 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 "desertcart Prime" sticker on it. I was pleasantly surprised, since I'm not an desertcart 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 desertcart for ... $40 MORE! There is no difference whatsoever between the drive in my hands and the one shown on the desertcart 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. ## Features - Included WD Backup software makes backing up what's important to you easy and fast - Easy to use WD Backup software makes protecting what's important to you easy - Downloadable version of AcronisTrue Image WD Edition software offers system-level backup for complete protection - Compatible with Windows(R) File History, included on Windows 8 and Windows 10 - Password protection with hardware encryption keep your private stuff private - USB 3.0 for fast data transfer rates ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E3RH61W | | Additional Features | Hardware Encryption | | Best Sellers Rank | #460 in External Hard Drives | | Brand | WD | | Built-In Media | Desktop Hard Drive, USB Cable, AC Adapter, WD SmartWare Pro Software, Quick Install Guide | | Cache Memory Installed Size | 4 | | Color | Black | | Compatible Devices | Desktop | | Connectivity Technology | USB | | Customer Package Type | Standard Packaging | | Customer Reviews | 4.5 4.5 out of 5 stars (4,634) | | Data Transfer Rate | 5000 Megabits Per Second | | Digital Storage Capacity | 4000 GB | | Enclosure Material | Aluminum | | Form Factor | 3.5-inch | | Global Trade Identification Number | 00718037812021 | | Hard Disk Description | Desktop | | Hard Disk Form Factor | 3.5 Inches | | Hard Disk Interface | USB 3.0 | | Hard-Drive Size | 4 TB | | Hardware Connectivity | USB | | Installation Type | External Hard Drive | | Item Weight | 2.3 Pounds | | Manufacturer | Western Digital | | Media Speed | 625 MB/s | | Model Name | My Book | | Model Number | WDBFJK0040HBK-NESN | | Number of Items | 1 | | Specific Uses For Product | Personal | | UPC | 088020916143 718037812021 | | Unit Count | 1.0 Count | | Warranty Description | 5 Year Dealer Warranty | ## Product Details - **Brand:** WD - **Color:** Black - **Compatible Devices:** Desktop - **Connectivity Technology:** USB - **Digital Storage Capacity:** 4000 GB - **Hard Disk Description:** Desktop - **Hard Disk Form Factor:** 3.5 Inches - **Hard Disk Interface:** USB 3.0 - **Installation Type:** External Hard Drive - **Special Feature:** Hardware Encryption ## Images ![4TB My Book Desktop External Hard Drive - USB 3.0 - WDBFJK0040HBK-NESN,Black - Image 1](https://m.media-amazon.com/images/I/61nP6tI7XSL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Will this work with the Xbox One?** A: I use this on my Xbox One and it works awesome. It has a faster drive speed than the on board drive for the Xbox, so I get faster load times. Not joking, I'm usually the first in the server on BF1, so I get a tank to start almost every game. **Q: can I eat this?** A: Sir/Ma'am, You may eat this and anything else that you desire.. **Q: Is this product compatible with time machine** A: You'll need a time machine if you want to buy this hard drive for a decent prize. 6 years ago I purchased this 4TB hard drive for $114. Today, the exact same hard drive is on sale for $169.99. So much for advancements in technology. **Q: Does this work with Apple Time Machine after formatting it to Mac?** A: I don't know that it does. When you go to the website you can select whether you need info related to either a PC or a Mac. My original answer related to Time Machine which is incorporated into the Mac OS. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Another solid WD product *by J***E on October 19, 2013* I purchased this drive largely based upon a specific need for a USB 3.0 product with 4TB of storage.

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! ## Frequently Bought Together - WD 4TB My Book Desktop External Hard Drive - USB 3.0 - WDBFJK0040HBK-NESN,Black - WD 20TB Elements Desktop External Hard Drive, USB 3.0 drive for plug-and-play storage - WDBWLG0200HBK-NESN - WD 1TB My Passport, Portable External Hard Drive, Black, backup software with defense against ransomware, and password protection, USB 3.1/USB 3.0 compatible - WDBYVG0010BBK-WESN --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/1180537-4tb-my-book-desktop-external-hard-drive-usb-3-0](https://www.desertcart.tn/products/1180537-4tb-my-book-desktop-external-hard-drive-usb-3-0) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-04-23*
