The Sandisk Extreme 1TB is an outlier, a one-of-a-kind, one that will satiate, even temporarily, the thirst for massive storage capacity that a growing audience demands. Professionals that require storage on the go will love the flexibility and the performance of this card; price is likely to be a minor factor in their decision process especially when you factor in the time saved from shuffling lower capacity cards around. 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). For 64GB-1TB ONLY: A2 performance is 4000 read IOPS, 2000 write IOPS. For 32GB: A1 performance is 1500 read IOPS, 500 write IOPS. Results may vary based on host device, app type and other factors. In theory, the Micron C200 is the only competitor to the Sandisk Extreme 1TB; the problem is that there are none available anywhere. Clearly there is a supply issue with Micron and we’re not sure why. Two smaller players (Silicon Power and Integral) have confirmed that they will launch 1TB microSDXC cards in 2020 but unlike Sandisk or Micron, they don’t control the production of the memory chip that goes inside the card. Drone operators will also appreciate the fact that it can be operated during extreme weathers and temperatures. Dashcam users may want to consider a memory card with higher endurance like the SanDisk MAX Endurance series which promises to last up to 120,000 hours of recording.
From SanDisk, the brand professional photographers worldwide trust to handle best shots on their toughest assignments. 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. 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. The Extreme Pro will appeal to a particular niche, one that craves for speed and wants something that is portable and can withstand more than a few bumps. It comes with a five-year warranty and its size and weight will turn it into a favourite storage companion especially with the hardware encryption. 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.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. Since 1982, PCMag has tested and rated thousands of products to help you make better buying decisions. See how we test. 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
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.] Get powerful NVMe™ solid state performance featuring 2000MB/s 2 read/write speeds in a portable drive that’s reliable enough to take on any adventure. 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 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 Extreme Pro leverages our lightning-fast in-house NVMe technology to dramatically increase transfer speeds to up to 1050 MB/s 6 and fully saturate the USB 3.1 Gen 2 interface. 6 So you’ll be able to edit right from the drive – providing full-frame editing with little interruption while saving you time and keeping your computer’s internal storage free.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. 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.) Compatible device required. Full HD (1920x1080) and 4K UHD (3840 x 2160) support may vary based upon host device, file attributes and other factors. See www.sandisk.com/HD 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. 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.
