- 01A lightweight format for the tightest carry-on luggage.The first notable feature of the WD My Passport SSD is its lightness. Weighing only 45.7 grams, it is one of the lightest drives on the market [1]. Its dimensions of 100 x 55 x 9 mm allow it to fit into a pocket or the narrowest compartments of a camera backpack. This is a valuable asset when cabin baggage weight restrictions force drastic choices, allowing you to carry multiple backup drives where a traditional drive would quickly exceed the allowed limit. The metal casing provides appreciable structural rigidity despite its thinness. Western Digital offers this model in a range of finishes, from classic gray to blue, red, gold, or silver, making it easier to distinguish the drives when managing complex data flows. In tropical climates, this metal structure acts as a passive heat sink, protecting the integrity of the components against slowdowns during extended copying sessions at the end of the day.
- 02Performance and Security: The NVMe Engine Under the HoodBeneath its minimalist design, the WD My Passport SSD incorporates NVMe technology to meet the demands of modern workflows. It boasts sequential read speeds of up to 1050 MB/s and write speeds of up to 1000 MB/s [1]. These performance levels are optimized for a connection via the USB 3.2 Gen 2 interface at 10 Gb/s, ensuring the smooth operation required for processing large files from the latest high-resolution sensors. For an underwater photographer, these figures translate into valuable time savings when offloading memory cards after a dive. The bus-powered design simplifies installation by eliminating the need for external power, as the drive operates directly from the USB-C port of a computer or tablet. Data security is ensured by hardware-based AES 256-bit encryption, which can be activated with a password, providing added peace of mind for those who transport professional images around the world [1].
- 03Protection and limitations: strictly for use out of the water.The WD My Passport SSD is not an all-terrain device in the strictest sense. Unlike some ruggedized models, this drive does not have any official certifications against dust or water ingress [2]. This lack of waterproofing requires strict precautions on a boat, where ambient humidity and salt are natural enemies of any unprotected electronics. Therefore, using a hermetic transport case, such as a dry box, or a waterproof pouch is essential whenever you leave the dry area of the vessel. In terms of physical resistance, Western Digital states that it offers protection against drops of up to 1.98 meters [1]. This value is reassuring for everyday handling, such as an accidental slip from a workbench, but it remains below the standards of rugged drives. The metal casing, while solid, will show scratches more easily if transported without protection in contact with other metal accessories.
- 04Compatibility and accessories: ready for the field.The drive comes with a USB-C to USB-C cable, which is compatible with most modern laptops and tablets. Western Digital also includes a USB-C to USB-A adapter. While convenient for connecting the drive to older machines, using this adapter mechanically limits performance to older USB standards, which can halve the data transfer rates. The limited 5-year warranty offered by the manufacturer is a positive sign regarding the expected durability of the internal components [1]. In the external storage market, such a warranty period is typically reserved for premium products, which further instills confidence for heavy use during extended trips. This is a valuable feature for users who cannot afford hardware failure in the middle of an expedition.
- 05Who is this SSD for?The WD My Passport SSD is primarily aimed at underwater photographers for whom the total weight of the bag is the biggest concern. Its performance-to-weight ratio is excellent, making it an ideal candidate for air travel where every kilogram counts. It easily fits into a jacket pocket while offering the responsiveness of an internal drive, allowing you to process your images directly from the external storage device. It also serves as a very useful secondary backup unit for storing the copy you keep with you, while a more robust drive provides the primary backup that remains in the cabin. For those who prioritize compactness and speed in a controlled environment, the My Passport SSD performs its task effectively. By providing it with the moisture protection it doesn't have inherently, you'll have a reliable tool capable of keeping up with the fast pace of daily downloads.
Questions about the Journal
Is the WD My Passport SSD waterproof?
This model does not have any IP certification for water or dust resistance. It is necessary to keep it in a waterproof housing or a dry bag during dives to avoid any contact with splashes.
Can it be used directly with an iPad Pro?
The USB-C connection and bus-powered design allow for direct use with an iPad Pro. This setup makes it easy to download photos in the field without needing a laptop.
Does the metal housing get very hot?
The aluminum enclosure dissipates the heat generated by the NVMe components. While it may become warm to the touch during large data transfers, this is normal and helps maintain stable transfer rates.
