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: Sturdy, Fast USB 3.0 Backup (Compatible with USB 2.0). - I've had good experiences with portable WD HDs before, so I picked this up mostly to save disk images of the computers in my house. This drive comes with software loaded on it for you to install: a utility to test and diagnose the drive, as well as a back up software solution; there is also a "driver" for this drive, but I'm not clear what it is suppose to accomplish since Windows recognized the My Book's full capacity without it. The utility is useful, but I didn't use the back up software -- rather I downloaded the "Acronis True Image WD Edition" software from WD's website. In fact, I installed Acronis, created a bootable Acronis disc, then uninstalled Acronis. I made an ISO copy of the bootable Acronis disc backup software. Acronis WD edition only works with WD drives attached to your computer. To test this portable drive I did a full erase filling the disc with zeroes (I used the Acronis bootable disc for this). What this accomplishes is that if there is a problem the software will tell me, and any defects will be replaced by good sectors through the SMART function of the drive. This took about a day and a half. I then tried to format the drive in Windows, I could not. Windows saw the My Book as two 2TB discs -- kind of strange. (Could a RAID 0 of two 2TB discs be inside what appears to be a single HDD?) Anyway, I zeroed the drive again using the supplied Windows WD utility and it only took a moment. That reset the drive so that it was viewed as one, blank 4TB drive in Windows. I then formatted the drive as NTFS with Windows. That took about a day and a half. So, there doesn't seem to be any defects. The drive works like regular drives, no funny business, and the drive is backward compatible with USB 2.0. This is a very solid and sturdy piece of equipment. Now, WD is known to supply back doors to the NSA. I'm suspicious by nature, but don't have delusions of grandeur so as to think the NSA actually wants to spy on me. I wonder why my firewall is telling me the WD utility is trying to call out several thousands times a day. (I have my firewall block this.) So my advice is to test the drive to your content offline if you're using the WD software and only use WD software when you're offline -- otherwise firewall block it or uninstall it. The Acronis bootable disc doesn't call home and is used offline. ## 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 | #535 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 out of 5 stars 4,633 Reviews | | 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 | | Special Feature | Hardware Encryption | | Specific Uses For Product | Personal | | UPC | 088020916143 718037812021 | | Unit Count | 1.0 Count | | Warranty Description | 5 Year Dealer Warranty | ## Product Details - **Digital Storage Capacity:** 2 TB - **Hard Disk Interface:** USB 3.0 - **Connectivity Technology:** USB - **Brand:** WD - **Special Feature:** Hardware Encryption - **Hard Disk Form Factor:** 3.5 Inches - **Hard Disk Description:** Desktop - **Compatible Devices:** Desktop - **Installation Type:** External Hard Drive - **Color:** Black ## Images ![WD 4TB My Book Desktop External Hard Drive - USB 3.0 - WDBFJK0040HBK-NESN,Black - Image 1](https://m.media-amazon.com/images/I/61nP6tI7XSL.jpg) ![WD 4TB My Book Desktop External Hard Drive - USB 3.0 - WDBFJK0040HBK-NESN,Black - Image 2](https://m.media-amazon.com/images/I/71GRzHK5-HL.jpg) ![WD 4TB My Book Desktop External Hard Drive - USB 3.0 - WDBFJK0040HBK-NESN,Black - Image 3](https://m.media-amazon.com/images/I/71zGXjMHeGL.jpg) ![WD 4TB My Book Desktop External Hard Drive - USB 3.0 - WDBFJK0040HBK-NESN,Black - Image 4](https://m.media-amazon.com/images/I/71d7aE-iTqL.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.

The first I use for storing feature films, concerts etc. in my home theater room. You can store several hundred feature films in the highest quality on this product with 6TB of memory and it connects to my DVR and provides three times the memory of the DVR itself. I use a second for all music files, photos, etc. and connect that one to a MINIX media player in my home theater room. While all of these files for films, music, etc. can fit on one box for now, I am anticipating the time when I will need to split them up and since I connect them to separate devices, it made sense to divide things up and prepare for the future. The WB My Book is very effective for storage and yes, you can use it to back up computer files too. It is quick for storing and retrieving, quiet, and offers a large amount of storage. This device is normally "on" at all times since it doesn't have an on-off switch. However if you connect it to a DVR, media player, or computer via a USB cable, and shut that device off for the night, you will turn this unit off at the same time. ## Frequently Bought Together - WD 2TB My Book Desktop External Hard Drive - USB 3.0 - WDBFJK0020HBK-NESN - Western Digital 8TB My Book Desktop External Hard Drive, USB 3.0, External HDD with Password Protection and Backup Software - WDBBGB0080HBK-NESN - Seagate Portable 2TB External Hard Drive HDD β€” USB 3.0 for PC, Mac, PlayStation, & Xbox -1-Year Rescue Service (STGX2000400) --- ## 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.pe/products/1202729-wd-4tb-my-book-desktop-external-hard-drive-usb-3](https://www.desertcart.pe/products/1202729-wd-4tb-my-book-desktop-external-hard-drive-usb-3) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-04-22*
