External hard drives are vital for efficient data storage, particularly in professional settings. SanDisk’s Extreme PRO with USB4 features rapid data transfer speeds, robust protection with a silicone cover and aluminum casing, and impressive portability. It offers easy compatibility with various devices, supports high-speed transfers ideal for video editing and gaming, and includes security options. While priced around 300 euros for 2TB, alternatives like the Corsair EX400U and Samsung Portable SSD T7 offer budget-friendly options for users with less demanding needs.
External hard drives have become essential tools in our daily lives, offering an efficient and secure means to store substantial amounts of data. This is especially true in professional environments, where powerful models are sought for tasks like video editing, gaming, and backup solutions.
SanDisk’s Extreme PRO with USB4 is designed to cater to these needs, boasting quick and effective data transfer capabilities. This drive not only serves as a high-performance storage option but also safeguards your data with a sturdy silicone cover and aluminum casing, making it suitable for various settings. In this review, we will evaluate whether the product lives up to SanDisk’s promises.
Design and Build Quality
The Extreme PRO stands out due to its durable and compact construction. With a robust aluminum exterior encased in a shock-resistant silicone layer, it is perfect for users on the move. Notably, this drive is water-resistant according to IP65 standards and has successfully withstood spills during testing. Weighing in at just 172 grams and measuring 140 x 68.7 x 11.9 millimeters, the 2-terabyte model is designed for portability.
The compact design ensures easy handling, while the silicone shell adds an extra layer of protection against impacts. Additionally, the SSD is equipped with a small loop for attaching a carabiner, eliminating the need for an extra bag.
User Experience and Compatibility
Using the SSD is a breeze; it requires no additional software installation and is ready for data storage or transfer as soon as it’s plugged in. It seamlessly connects to older devices sporting USB 2.0 ports in USB-C format. The hard drive also supports Thunderbolt 4, making it compatible with devices like the 2021 MacBook Pro (16 inches) and the 2023 Mac mini.
Formatted in the exFAT file system, the SSD is compatible with both Windows and macOS. In our tests, we had no issues connecting it to an iPhone 15 Pro Max, where it was instantly recognized within the iOS file system, making it a versatile extension of internal storage. However, the included USB-C cable could be longer, as it measures just 30 centimeters.
Portability and Durability
External storage devices are now available in various sizes, but the Extreme PRO USB4 excels in portability, easily fitting into bags or backpacks. During our tests, the silicone cover successfully absorbed impacts, as it survived falls from about 2 meters onto asphalt without showing signs of damage.
Its water resistance further enhances its utility during outdoor activities, ensuring that it remains functional even in wet conditions. For instance, users can confidently place the SSD near cooking areas in camper vans without fear of damage from splashes.
The Extreme PRO USB4 is also a strong candidate for office environments, like home offices, where it can be utilized for system backups in Windows Backup or via Time Machine on Mac systems.
Performance and Speed
Thanks to its USB4 technology, the SSD offers impressive speed that surpasses many contemporary models. SanDisk claims read speeds of up to 3,800 MB/s and write speeds reaching 3,700 MB/s. However, our tests showed a maximum write speed approximately 600 MB/s slower on an iMac with an M4 chip. These figures can vary based on the testing software used, and performance may improve with different benchmarks on Windows machines. To achieve peak performance, a device equipped with USB4 or Thunderbolt 4—like the Asus Zenbook A14 or a MacBook with an M4 chip—is recommended.
During our tests, transferring a ten-gigabyte file took only 12 seconds, while a traditional mechanical hard drive, such as the Toshiba Canvio Flex, needed around 1 minute and 20 seconds for the same task. This efficiency makes the Extreme PRO USB4 suitable for professional applications, including 4K video editing and high-resolution photo work.
Security Features and Data Management
For users concerned about data security, the SSD offers an option to set a password through the SanDisk Security application, which features 256-bit AES hardware encryption to protect against unauthorized access. This security measure is commonly found in modern SSDs, and it can be configured on both Windows and macOS platforms.
SanDisk claims that files on the SSD can be managed using the proprietary Memory Zone app for iOS and Android devices. However, our tests revealed that the app is only compatible with select USB-C and Lightning sticks from the manufacturer, necessitating file management through the operating system on other devices.
Energy Efficiency and Noise Level
The Extreme PRO USB4 draws power directly from the USB-C port, eliminating the need for an external power supply. Its energy consumption is dependent on usage levels, increasing during heavy data writing tasks. Thanks to USB4 technology, this SSD boasts improved energy efficiency compared to older standards.
Since the drive relies on flash memory and lacks moving parts, it operates silently. Unlike traditional hard drives, it produces no operational noise or vibrations, making it an excellent choice for noise-sensitive environments.
Ideal Use Cases for the Extreme PRO USB4
This SSD is highly recommended for individuals who require high-speed data transfers. Photographers, videographers, and content creators working with large 4K or 8K files can directly access their projects from the SSD without delays. SanDisk also backs this product with a five-year warranty, which is longer than many competitors’ three-year offerings.
Gamers can also benefit, as the SSD serves as an external storage solution for video games. Its compatibility extends to PCs, Macs, and modern gaming consoles like the PlayStation 5 and Xbox Series S/X. However, those who only need occasional backups or do not require ultra-fast transfer speeds may want to consider more affordable USB 3.2 SSDs.
Cost and Alternatives
As of our testing, the 2-terabyte Extreme PRO is priced around 300 euros, while the 4-terabyte model retails for nearly 470 euros. For those seeking a more budget-friendly USB4 SSD, the Corsair EX400U is a viable alternative, though it is not as durable and lacks hardware encryption.
For users without USB4 or Thunderbolt 4 devices who do not need the Extreme PRO’s maximum speeds, considering a USB 3.2 SSD is wise. The Samsung Portable SSD T7, which offers data rates of approximately 1,000 MB/s, is an excellent choice, priced around 100 euros for one terabyte.
