Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions. See how we test.

Whether you’re trekking through snowy mountains or filming in the middle of the desert, this drive won’t let you down. 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. As for IOPS - what is the point of testing the device outside of its designed enclosure if it is forever going to be used in the enclosure? I can test portable SSDs' IOPS perfectly fine as they come. They are not going to be used as internal SSDs, only as portables. So, comparing the performance without the bridge chip they come with is irrelevant. And again, I've already reviewed the internal devices as linked above. ;) On a positive note, the drive comes with two 9-inch cables: USB-C-to-USB-C and USB-C-to-USB-A. That's better than an awkward converter dongle. 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.Ruggedized design with a forged aluminum body to protect the SSD core and dissipate heat. Plus, a durable silicon rubber coating seeks to deliver higher impact resistance with its IP55 rating for water and dust resistance. 1

There are plenty of external storage solutions out in the market, but very few of them will be as durable as the Extreme Pro Portable SSD. It’s got great transfer speeds to keep you going, plenty of storage, and comes in a variety of storage sizes. TB3 is more popular then USB 3.2 2x2 which is impossible to find in notebook and very rare in Desktops. The Extreme Pro is IP55 water and dust resistant and rated to withstand a two-meter drop, though we feel that is a very conservative rating. At 85 grams, the Extreme Pro has a solid and weighted feel to it. That, along with the smooth rounded silicone-coated edges, conveys an apple-esque quality. seanwebster said:At that point you wouldn't be testing the actual portable SSDs as they are, you would just be testing the performance of the internal SSDs in that one enclosure. Thus, comparing just the underlying storage alone. You can't compare the performance or thermal characteristics of these portable SSDs without using the default enclosures and bridge chips.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. 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.] 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.
