WD My Passport Wireless SSD Overview
So, what is the WD My Passport Wireless SSD, and how does it differ from its predecessors? In a nutshell, the WD My Passport Wireless SSD is an external hard drive that has a built-in SD card slot, wireless capability and an integrated battery in order to be able to back up attached media without needing constant external power, or a computer to connect to. It is a built to be a rugged device that can survive quite a bit of abuse, including occasional bumps and drops (it is not water or dust-proof though). When compared to its predecessors and as the name suggests, the WD My Passport Wireless SSD is the first of its kind to feature SSD drives instead of conventional spinning hard drives, which makes it not only significantly faster (up to 390 MB/sec read speed), but also much more reliable in the long term for backup needs. It features a powerful 6,700 mAh battery that can be used to either power up the device (with up to 10 hours of continuous use), or to function as a power bank to provide charging to other devices such as smartphones and tablets.
Let’s take a look at the detailed specifications of the WD My Passport Wireless SSD.

As you can see, the WD My Passport Wireless SSD is a pretty expensive device, especially if you go for larger capacities. Personally, I would not recommend to buy the 250 GB model, since you are paying almost a dollar per GB, which is extremely expensive, even for an SSD drive. I would skip the 500 GB version as well (60 cents per GB) and would either get the 1 TB model (50 cents per GB) or the 2 TB model (40 cents per GB).
Charging WD My Passport Wireless SSD
Charging the device is pretty easy – you can either use the provided 2.4A wall adapter, or connect the device to a USB port of any device that can provide power. Once power is connected, the four LCD indicator lights will blink and provide information on how much charging is left to do. Each bar represents roughly 25%, so if you see three bars light up and the fourth one flashing, it means that the charge is currently above 75%. Once the battery is fully charged up, all four LED lights will stay lit up. Obviously, if you want to be able to charge the device faster, it is better to use a more powerful charger that can provide sufficient amperage.
Below is the layout of all the ports and buttons on the device:
As you can see, there is a dedicated power button, along with an SD / Battery button that is used to check battery level, or start copying the contents of an inserted SD card. The micro USB 3.0 port is used for charging and connecting to a computer, whereas the USB 2.0 Type A port is used for connecting external storage / media card readers, as well as powering up portable devices.
Setting up the WD My Passport Wireless SSD was a breeze. After the unit got fully charged, I pressed the power button to start it up, and while it was starting up, I installed the “WD My Cloud” app from the App Store. After firing up the application, I let it find my home wireless access point, and went through the process of connecting to it. After the device joined my network, I got a notification to register the device:
The app checked if I had the latest firmware update (which I did), and I was already running the latest and greatest firmware 1.04.17. As always, it is a good idea to update to the latest firmware release, as it might address bugs, as well as add more camera support in the future.
Once the unit is set up on your wireless network, you can connect to it through its web interface. If you are a Windows user, you can try opening up the URL http://mypassport and if you are a Mac user, try http://mypassport.local in your browser. If you know which IP address the device pulled from your network, you can also access the web interface directly by typing the IP address:
It is a very clean, user-friendly interface through which you can access WiFi settings and Admin, Hardware, Media, Support and Firmware sections. There are a number of important options in those tabs and you might want to go through each one individually. For example, you will find quite an important setting called “Import Mode” under “Media”, which allows you to either copy everything from an inserted SD card, or only copy new files. This way, if you still have space in your card and you want to keep shooting to it, you don’t have to duplicate data each time you insert the memory card.
For those who like being able to stream content from the device, you can also install the Plex Media Server. Since I have no plans on streaming content from mine and I only want to use it to backup my memory cards in the field, I skipped through this process.
Below the setup tabs you will find a nice summary of what’s going on in the device. The chart, along with the information to the right of it, will display how much content you are storing on the device, grouped by type. To the right of that, you will find a battery level indicator, below which WiFi information is also provided. Lastly, you will find the model of your device, along with the firmware on the bottom of this screen.
To access files on the device, I would recommend to connect it directly to the computer (see below), since it will take forever to do the same over the wireless network. However, if you do insist on going this route by mapping the device over the network, you will need to install the SMB 1.0 protocol, which is not a secure way to transmit data, but it will certainly do the job.
Mobile Device Media Content Auto Backup
While going through the setup process, I was asked if I wanted to automatically back up photos and videos on my iPhone. I thought it would be a good idea to give it a shot, but this turned out to be a pretty bad idea at the end. While the setup process was easy, as soon as syncing data from my phone got kicked off, it completely froze the WD My Cloud app and crashed it a number of times. I had to manually stop the process, disable auto backup, then wipe the added media files out afterwards (my iPhone HEIC files weren’t recognized anyway). During this process I experienced a number of bad bugs related to the app, one of which was the “File not found” error, which kept on showing up after I marked images for deletion. It turned out that the app wasn’t quick enough to sync with the changes that were taking place on the device, causing these errors. Here are some screenshots:
After going through this pain once, I never attempted to back up my phone again.
One of the features of the WD My Passport Wireless SSD is ability to install cloud services from different providers to the WD My Cloud app. For example, if you have a Dropbox account, you can install the Dropbox service and browse through your Dropbox content. The screenshot below shows the different cloud service options that are available to add:
Unfortunately, as cool as adding a cloud service might sound, I did not find it to be of much use for a number of reasons. First of all, these are simply ways to connect to cloud services, nothing more. Adding a service will not make the WD My Passport Wireless SSD act as a client, so you will need to manually copy folder contents from your cloud provider to the device before you can access them in the field. Second, I found the process of copying data from a cloud provider to be painfully slow, something I could easily avoid by just plugging it directly into my computer. Lastly, if I were to do this in the field without access to WiFi, trying to copy anything from the cloud would eat up quite a bit of data. Because of all these issues, I ended up disabling cloud services completely.
If you find yourself wanting to sync up your data to the cloud via Dropbox or some other service, your best bet would be to connect the drive directly to your computer, then configure your desktop client to sync with the folders on the device.
RAW File Support
What’s nice about the My Passport-series devices, is that you can preview RAW files from many different cameras when using the WD My Cloud app. The software is able to read thumbnails from RAW files (using the embedded JPEG thumbnails in RAW files), so you can preview images from both SD cards and the built-in storage. Many camera brands and models are supported from a number of different manufacturers, including Nikon, Canon, Sony, Pentax, Fuji, Panasonic, Olympus and others. The full list of supported cameras is provided here. Interestingly, even some medium format cameras such as the Fuji GFX 50S and Hasselblad X1D-50c are supported, which is great!
Inserting / Removing SD Cards and Backing Up Data
Inserting and removing SD cards is a pretty straightforward process (it works just like doing it on a camera), but there are a few things one should keep in mind. When going through settings, if you enable the “Automatic Import” option under “SD card”, inserting the memory card will automatically kick off the backup process. By default, the option is not enabled, which means that you would first have to insert a memory card, then press the “Battery / SD” button on the side of the device to start the backup process. If the backup process starts, you should wait until the copy process fully completes before attempting to remove the card. Ideally, you should first “Eject” the card through the WD My Cloud app or through the web interface, just like you would on your computer to make sure that there are no active transfers taking place. Otherwise, you risk potentially corrupting the memory card and losing data on it.
Once the SD card backup starts, you will be able to monitor the copy process by checking out the progress bar in the WD My Cloud app. Keep in mind that the same four LED lights on the top left side of the unit that are used to check the charge progress are also used during the SD card backup process. Once the backup is done, all four lights should be lit up and the Wireless SSD light should stop blinking. Below is a screenshot of the WD My Cloud app, showing the copy progress during an SD card backup:
If you made an error and you want to terminate the transfer process, you can touch the “Stop” button to the right of the progress bar. Again, make sure to properly eject the drive before physically removing the card to prevent card corruption.
While inserting and removing memory cards, I encountered a few bugs with the unit. Occasionally, the unit would not recognize an inserted memory card. Simply removing and re-inserting the card worked out, but it is certainly something you should keep in mind, especially if you have the “Automatic Import” option enabled. I ended up disabling that option and decided that it would be better to kick off the backup process manually, which reduced chances of my data not getting backed up.
Use as a Power Bank
Personally, I love the option to be able to use the WD My Passport Wireless SSD as a power bank. Since I often end up taking a power bank with me when traveling, I can now skip it and bring this gadget instead. The only thing I don’t like is the size – at about twice to three times the size of an equivalent power bank, this is not a small device to carry around, and it takes up more space in the camera bag. I wish WD came up with a way to split My Passport Wireless SSD into two separate units: one that has the SD card port, SSD drive and other input/output ports, and the other one only sporting the power bank, with one input and one output ports. If done right, the two could then be connected together in a simple snap-in / snap-out way. This would have been a great solution, since it would have given the option to the end user on how they want to transport the device and what part(s) they want to take with them. For a laptop user, having a built-in SSD with an SD card slot would be sufficient, since power could be provided through the USB port. For a photographer wanting to skip a laptop, it would make sense to bring both the main unit and the power bank. Oh well, perhaps in the next version!
Connectivity Concerns – I/O Ports
Speaking of USB ports, I was disappointed that Western Digital is still pushing standard USB Type A and micro USB ports when the whole world has been transitioning towards USB Type C. This means that MacBook users (as well as PC users with only USB Type C ports) will still have to use adapters to connect to My Passport Wireless SSD, which is unfortunate. Instead of connecting the device via micro USB 3.0 for charging and computer connectivity, WD should have used USB Type C to do both.
What really baffles me, however, is the fact that WD used a USB 2.0 Port for external drive and memory card reader connectivity. I am not sure if it was done due to specific chipset limitations, but come on – who on earth is using USB 2.0 on a modern device? This essentially means that if you use other type of media such as XQD, CFast or SD UHS-II, you will be stuck with unbelievably slow transfer rates! See some notes below on abysmal transfer rates when using an external memory card reader…it is pretty bad!
Connecting to Computer
While it is possible to use the WD My Passport Wireless SSD wirelessly at all times, that’s not the route you want to take if you want to be able to copy anything fast to or from the device. To reach the benchmark numbers provided below, you will need to plug the included USB cable into the device (with the micro USB 3.0 end), and plug the other USB Type A end into your computer.
Once plugged in, the device will automatically turn off WiFi and switch to mass storage device. By default, the file system is formatted for NTFS, so if you are a Mac user, you might want to reformat the drive in APFS file system, so that you can read and write to the device.
If you do not want to connect to the device and you want to charge it up instead, simply eject the media, and the device will switch to charge mode automatically.
Benchmark – CrystalDiskMark
For some reason, Western Digital only provided maximum read speed for the drive in its technical specifications, which was advertised at “up to 390 MB/sec”. I benchmarked the WD My Passport Wireless SSD using CrystalDiskMark and it turned out that the advertised speed is in fact pretty darn accurate – I was able to reach around 387.4 MB/sec of sequential read speed. Interestingly, the write speed was also pretty similar – I was able to get 384.9 MB/sec sequential write speed. You can see the results for yourself below:
This means that you should be able to get pretty fast speeds when copying large files (such as video files), but if you are dealing with many smaller files (such as JPEG or RAW images), expect to get slower speeds, which is quite normal. While the above numbers are not groundbreaking, especially when compared to modern M.2 NVMe drives (see NVMe vs SSD vs HDD), they are pretty decent. Western Digital uses SanDisk SSD drives within the device, which makes sense, considering that WD owns SanDisk.
Benchmark – SD Card Backup
While I was pretty unhappy about how slow Gnarbox backs up images from SD cards, I wondered how WD My Passport Wireless SSD would do in comparison. When I copied approximately 53 GB of data to Gnarbox, it took a total of 45 minutes and 27 seconds, something I was very unhappy about, as it only took around 11 minutes to copy the same data to my computer. I popped exactly the same card into the WD My Passport Wireless SSD and started the timer. I am happy to report that it performed significantly faster, at just 14 minutes at 31 seconds – about three times faster than the Gnarbox. That’s pretty impressive, considering that my computer was only three and a half minutes faster.
Battery use was also managed very well – the device went from 100% to 92%, which is great, considering how much data was moved. This means that I could essentially back up about 500 GB of data on a single charge!
Benchmark – External Media Card Reader Backup
As I have already pointed out above, it is unfortunate that WD features a slow USB 2.0 interface to connect other storage and media card readers. Just to see how the speed of USB 2.0 would compare to a backup process using the built-in SD card reader, I connected my Lexar USB 3.0 memory card reader to the device, then inserted the same 128 GB card with 53 GB of data, to see how long it would take to copy this data.
Unfortunately, the results were very disappointing – it took a total of 34 minutes and 12 seconds to back up the same data, something it was able to do at less than half the time with the built-in SD card reader. You can only imagine how painful it will be to transfer files from XQD, CFast and other fast media types…you will need to wait a while for the process to finish. On the positive side, the transfer process was still faster and the battery discharge was still far more efficient compared to what I had previously seen on the Gnarbox. I transferred the same 53 GB data twice and managed to back up another full 32 GB SD card and I still had 79% battery life left, even with the device powered on for quite a while during the process of writing this review.
It is exciting to see manufacturers like Western Digital create efficient and portable backup solutions for photographers. While I previously did not consider the WD My Passport-series devices for my backup needs when traveling, the latest Wireless SSD version is something I would certainly consider for my own needs and recommend to other photographers. It is a solid, rugged device that can withstand occasional bumps and drops; it is capable of doing very fast data transfers as a portable storage device, thanks to its SSD storage; its built-in SD card reader can transfer files from SD cards very quickly; its battery lasts a long time and can be used as a power brick to charge up other devices, and the WD My Cloud app works fairly well on iOS devices and is capable of previewing RAW files from many different cameras.
However, the device is far from being perfect. Aside from its large and bulky size, my biggest gripe is with the I/O ports that Western Digital incorporated into the unit. With all modern devices going with USB Type C connectivity, it was disappointing to see micro USB 3.0 and USB 2.0 Type A ports on this device. While the former is something many of us can certainly live with, those who are planning to use the device to back up data from external memory card readers will be sorely disappointed with the performance of the latter. This basically makes the device only useful for those who exclusively shoot with SD cards, which is rather disappointing to see. If Western Digital found a way to incorporate more memory card readers (XQD, CFast, SD and microSD) without adding to the size of the device, or provided a much faster USB 3.0 / 3.1 or Thunderbolt interface to connect external media card readers, it would make the WD My Passport Wireless SSD a far more practical device for the masses. Lastly, I would love to see the next iteration with sealed doors, so that it becomes a truly rugged, waterproof and dust-proof device.
