We devote hundreds of hours of rigorous testing to help make sure your drive is worthy of your best work — and so you know your precious files are in good hands.

For 256GB-1TB: Up to 200MB/s read speeds, engineered with proprietary technology to reach speeds beyond UHS-I 104MB/s, require compatible devices capable of reaching such speeds. Up to 140MB/s write speeds. For 64GB-128GB: Up to 200MB/s read speeds, engineered with proprietary technology to reach speeds beyond UHS-I 104MB/s, require compatible devices capable of reaching such speeds. Up to 90MB/s write speeds. For 32GB: Up to 100MB/s read speeds; up to 90MB/s write speeds. Based on internal testing; performance may be lower depending upon host device interface, usage conditions and other factors. 1MB=1,000,000 bytes. Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions. See how we test. Our tests show that the Sandisk Extreme Pro V2 performs on par with current USB 3.2 Gen 2 drives and that’s not a surprise. CrystalDiskMark, for example, hit more than 1GBps on sustained read and write speeds using default settings. The competition

Editor’s Note, August 17, 2023: As recently reported in Ars Technica , a critical mass of users on SanDisk’s forums and Reddit have reported failures of some SanDisk Extreme, Extreme Pro, Extreme V2, and Extreme Pro V2 SSDs, resulting in data loss, as well as the drives becoming unreadable/unmountable. In May, parent company WD released firmware updates for the 4TB SanDisk Extreme, as well as the 4TB, 2TB, and 1TB Extreme Pro models, plus the 4TB Western Digital My Passport, but complaints continue. We are doing our own stress-testing of the sample drives we originally reviewed. As of today, however, we no longer recommend buying any of the aforementioned SSDs, until we are satisfied the issue has been resolved. ( A class-action suit has been levied against WD surrounding issues with these drives.) We have left our original review in place here for reference.] We tested the Sandisk Extreme Pro 1TB external portable SSD using a Dell Latitude 7490 business laptop which is equipped with a Thunderbolt 3 port. Note that the Extreme pro Portable SSD v2 includes support for hardware encryption via the Sandisk SecureAccess application.

Save time storing and transferring data with the forged aluminum chassis that also acts as a heatsink to deliver higher sustained speeds. USB 3.2 Gen 1 (a.k.a. the old USB 3.0), typically good enough a ceiling for older external SSDs with SATA-based silicon, caps read and write speeds for external SSDs at about 550MBps and 500MBps respectively. While you can use the Extreme Pro V2 drive with any of these interfaces, buying it without provision for a Gen 2x2 interface would be like buying a Corvette for runs to the grocery store. UHS Speed Class 3 (U3) designates a performance option designed to support real-time video recording with UHS-enabled host devices. Video Speed Class 30 (V30), sustained video capture rate of 30MB/s, designates a performance option designed to support real-time video recording with UHS-enabled host devices. See www.sdcard.org/consumers/speed. We tested the Sandisk Extreme 1TB with a microSD card reader, on our Dell Latitude 7490 laptop. However, performance, as always, will depend on what card reader you use.

For those looking for an even faster microSDXC card, there’s the Sandisk 1TB Extreme Pro microSDXC card; it is far more expensive but almost doubles the read speeds to 170MBps and is fast enough to record in 8K or for your action camera. You will need a compatible reader to make the most out of it though. Final verdict The Extreme PRO® SSD works with PCs and Mac™ computers right out of the box and connects with USB Type C and Type A, 3 making it easy to start and keep working in almost any situation. From SanDisk, the brand professional photographers worldwide trust to handle best shots on their toughest assignments. You will need to have a compatible host device to make the most out of this Extreme Pro v2. Sadly, we didn’t have anything at hand to test its claimed performance. We suspect that a lot of potential customers will buy the drive and expect read/write speeds of up to 2GBps (as per the numbers on the box).

So you’re left with a conundrum: Buy a storage device that promises to be extremely fast but only in certain circumstances or get one of the many rugged USB 3.2 Gen 2 drives available for significantly less but will work with far more devices. Capture fast-action photos or shoot 4K UHD video 2 with write speeds of up to 140MB/s. 8 The SanDisk Extreme PRO microSDXC UHS-I Card lets you shoot more and faster. SanDisk provides a generous five-year warranty, which we have also seen on other Western Digital products such as the 2020 version of the My Passport SSD. (WD is SanDisk's parent company.) The same holds for laptop users (Windows, Chromebooks or MacBooks) that want an easy and cheap way to increase the internal, local storage capacity without resorting to swapping the solid state drive (and resorting to the dreaded process of disk cloning). Adding 1TB to a laptop with 128GB storage can now be done in seconds!

The small and light form factor of the Extreme PRO® SSD means it couldn’t be easier to keep your content with you whether you’re crossing town or traveling to an international location.
