User Experience
The portable SSD comes in a standard branded retail box. There is an image of the product on the front, and details about the product are outlined on the back. There is a side view of the drive that shows how thin the SSD is. I had the opportunity to work with the Extreme PRO’s predecessor, and its form was a bit smaller than this one. The USB4 version of this portable hard drive comes with a USB-C to USB-C cable and a small packet of information. It has a loop on the corner, which could be used to attach it to a backpack or laptop bag if the user wanted to.
One of the things I really enjoy about this hard drive is that it doesn’t require any fancy setup or software to get it started. You simply plug it in, the computer recognizes it, and you can get to work. I ran the hard drive through four different tests.
AmorphousDiskMark Blackmagic Disk Speed Test AJA System Test Lite Drag-and-Drop file transfer testEach one of these tests helps to provide insight into how quickly and efficiently the SSD transfers files and what it can be used for.
In the Blackmagic Disk Speed Test, the drive achieved write speeds of approximately 2683 MB/s and read speeds around 3095 MB/s. These results indicate full compatibility with high-bitrate video formats, including ProRes 422 HQ and H.265, even at ultra-high resolutions like 8K and 12K DCI. It also supports Blackmagic RAW recording up to 8K DCI 60p, making it an excellent choice for professional video editors and filmmakers.
In the AmorphousDiskMark benchmark, the drive reached sequential read speeds of up to 3442.89 MB/s and write speeds of up to 3222.73 MB/s. These figures highlight the drive’s ability to move large files quickly and efficiently, with strong sustained performance under heavy workloads. While random read/write speeds at smaller block sizes (such as 49 MB/s read and 56 MB/s write) are more modest, as expected for flash storage, they remain solid for general multitasking and system responsiveness.
The AJA System Test Lite provided further real-world validation using a 16 GB ProRes HQ file at 3840×2160 4K RED resolution. The drive delivered consistent write and read speeds of 2361 MB/s and 2962 MB/s, respectively, confirming its capability to handle high-resolution footage and long-duration media workflows without slowdowns or dropped frames.
With the real-world drag-and-drop file transfer test, I dropped a folder totaling 3.9 GB, containing various file types, onto the SSD. It was copied in just 58.47 seconds. This translates to an average transfer speed of around 67 MB/s, accounting for real-world variables like file system overhead, file sizes, and metadata. While this speed is lower than the synthetic benchmark figures, it reflects the kind of consistent, everyday performance users can expect when transferring diverse files. Combined with the drive’s stellar benchmark results, this real-world test reinforces its reliability and versatility in practical use cases.
Conclusion
The SanDisk Extreme PRO with USB4 Portable SSD proves to be an impressive step forward in portable storage technology. Combining blistering fast read/write speeds with rugged durability, it’s clearly designed for creators, gamers, and professionals who need speed and reliability in a compact form factor. Its USB4 interface ensures it remains future-proof and compatible across a wide range of devices, while real-world performance holds up well against synthetic benchmarks.
The drive’s plug-and-play functionality is a huge win, especially for users who want instant access without dealing with software or setup hassles. Whether you’re transferring massive video projects, editing directly off the drive, or simply backing up essential data, the Extreme PRO delivers professional-grade performance in a portable package. If you’re serious about speed, durability, and compatibility, this SSD is well worth the investment.
