SanDisk Extreme PRO 512GB SDXC Memory Card up to 170MB/s, UHS-1, Class 10, U3, V30

Product Information

Long story short, I connected both of the cards to my Mac and copied 2GB of data to and from each of them, using a stopwatch. Extreme Dive fearlessly into aquatic adventures as our card embraces complete waterproof protection up to an impressive depth of 10 meters, safeguarding your valuable data in any watery environment Embrace data recovery excellence with our complimentary RescuePRO Deluxe software, providing comprehensive file retrieval capabilities, ensuring you never lose cherished memories or critical files Card Type:SDXC | Capacity:Up to 512GB | Read Speed:Up to 95MB/s | Write Speed:Not specified | Warranty:Lifetime (limited) | Suitable for:High-speed burst photography and video (including 4K) Conclusion

With a few differences between both of these cards, it all comes down to your needs, if you are shooting mainly video, or if you shoot mainly in a studio tethered to a computer, I would personally recommend going for the cheaper option, which is the Extreme. However, if you are concerned about the transfer rate or if you depend on burst shooting, I would definitely recommend the Extreme Pro simply because it didn’t lag during the test. Elevate your storage capacity with our groundbreaking 512GB card, accommodating hours of breathtaking 4K video or thousands of stunning high-res photos in a single, compact solution

Get faster app performance for an outstanding smartphone experience thanks to the SanDisk Extreme PRO microSD card’s A2 5 Specification. It started very fast, taking around 3 photos per second for about 5 seconds. Then it went to around 1.5 photos per second for the rest of the minute without lagging or stopping at any time UHS Speed Class was introduced in 2009 by the SD Association and is designed for SDHC and SDXC memory cards. This, again, means that both of these cards will guarantee a minimum of 30Mb/s in the worst-case scenario. If you use a UHS memory card in a non-UHS host, it will default to the standard data bus and use the “Speed Class” rating, which in this case is Class 10, instead of the “UHS Speed Class” rating, which is U3. UHS memory cards have a full higher potential of recording real-time broadcasts, thereby capturing large-size HD videos and extremely high-quality professional HD. At the end of the test, it looked like both cards were almost similar in terms of speed. However, I would recommend the Extreme Pro, as it didn’t lag or stop in the middle. Transfer Speed

Sometimes speed is what you need. The SanDisk Extreme PRO SD UHS-I card delivers the performance to capture stunning, uninterrupted 4K UHD video 1. With shot speeds up to 140MB/s 6 the card is perfect for capturing the action as it happens, without missing a beat. 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.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. Write speed up to 140MB/s. Based on internal testing; performance may be lower depending upon host device, interface, usage conditions and other factors. 1MB=1,000,000 bytes. X = 150KB/sec. [64-128GB] Up to 200MB/s read speed. Write speed up to 90MB/s. Based on internal testing; performance may be lower depending upon host device. 1MB=1,000,000 bytes. X = 150KB/sec. [32GB] Up to 100MB/s read speed. Write speed up to 90MB/s. Based on internal testing; performance may be lower depending upon host device. 1MB=1,000,000 bytes. X = 150KB/sec. Card Type:SDXC | Capacity:Up to 128GB | Read Speed:Up to 300MB/s | Write Speed:Up to 299MB/s | Warranty:Manufacturer’s | Suitable for:High-speed burst photography and video (including 4K) 4- Transcend SDXC UHS-II U3

Video Speed Class or “V Class” was created by the SD Association to identify cards that can handle higher video resolutions and recording features. This speed class guarantees minimum sustained performance for recording video. This means that both of these cards will guarantee a minimum sustained speed of 30Mb/s

Thank you!

Ultra-High-Speed (UHS) is the new generation bus interface for SD cards. Succeeding the regular high-speed specification, UHS was recently designed to support devices with higher capacity and speed requirements. Memory card speed is confusing, as it is specified and advertised in different ways. The Read and Write speeds are different, NOT the same number (the camera writes, your computer reads). To simplify things, let’s focus on the three main parts of the ranking.

When you're shooting where the action is, the CFexpress Card Type B unleashes the RAW performance of your gear. With read speeds up to 1700MB/s and write speeds up to 1400MB/s, you'll get low latency during high-speed recording and an enhanced workflow efficiency that's far beyond anything existing SanDisk cards deliver.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 After you are done with your photos, you need to copy them to start the editing process. As you know, shooting in 4K video or RAW files takes up memory faster and file sizes are much larger. Have you ever waited for hours to finish copying your files? Also, keep in mind that the host device can greatly affect the transfer speed of a storage product. Speed Class is a minimum speed based on a worst-case scenario test, which means that both of these cards will guarantee a minimum of 10Mb/s. Compared to high-megapixel photography, video doesn’t need as big of a data pipe because the video format is a smaller “fixed stream” that uses only a portion of the data pipe. Also, your camera’s specifications should state the minimum Class Rating required.
