SanDisk Extreme PRO 128GB SDXC Memory Card up to 170MB/s, UHS-1, Class 10, U3, V30

Product Information

Rated UHS Speed Class 3 (U3) and Video Speed Class 30 (V30) 2, the SanDisk Extreme PRO SD UHS-I card lets you capture sequential burst mode shots without missing a beat.

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. 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 SD cards are flash memory, which means they have no moving parts and instead rely on electronic chips to store data. While they don’t require power to store data, they can be damaged via water, fire and physical pressure. Some companies offer bespoke 'tough' versions that can withstand these elements, even remaining safe in extreme temperatures, so it's worth looking for those if you're going on an adventure. It is not just cameras that use microSD cards, of course. And one of the most popular devices to use this memory type at the moment is undoubtedly the Nintendo Switch handheld console, and its baby brother the Nintendo Switch Lite. The slot in memory is not only great for expanding the number of games you carry, but also for taking screenshots and videos of your victories and adventures. One of the most obvious ways to differentiate between memory cards is how much storage they have. A 16GB card might be fine for an afternoon wandering around your local wildlife reserve, but videographers looking to shoot all day could get frustrated with having to constantly swap over cards.Our stand-out best SD card is the Transcend SDXC UHS-II U3. With a Class 10, V90, U3 and UHS-II rating, we thought it would be fast enough to capture almost anything modern devices could throw at it, but we weren’t expecting the speed results we got. For my first test of the 64GB SanDisk Extreme PRO 300MB/s SDXC UHS-II, I popped it into the 45.7MP Nikon Z 7II and set the camera to shoot at its fastest rate (10fps) with the focusing set to manual to rule out any focusing delays. When the camera was set to record 14-bit uncompressed raw files I was able to capture 38 images in a continuous sequence - putting it on par with the PNY X-Pro 90 SDXC UHS-II card and ahead of the Manfrotto Professional SDXC UHS-II card.

Full HD (1920x1080) and 4K UHD (3840 x 2160) video support may vary based upon host device, file attributes, and other factors. See: www.sandisk.com/HD

ProGrade Digital also has a 160GB Type A card you can buy, but it's not as readily available as this Sony equivalent, and is only marginally cheaper. Delkin has Type A cards coming soon though, so hopefully prices will start to fall further. XQD Actual transfer speeds under our testing churned out a write speed of 33MB/s and read speed of 82MB/s; not too bad, but the write speed is close to the minimum V30 classification on the label, so that's worth bearing that in mind if write speeds are important to your work. The cards are different colors depending on the capacity - so red with a Nintendo Mushroom icon for 128GB, yellow with a Super Star for the 256GB, and teal green for the 512GB card. You don't need these customized cards, as any microSD card will work in your Switch – but you will earn kudos points for brand loyalty. As an evolution of the XQD format, CFexpress is one of the best memory card formats around. However, it's currently only available with a limited number of high end cameras (mostly from Canon, Nikon and Panasonic). However, it's worth noting that the release of the Sony A7S III brought a somewhat confusing split into two different variants of CFexpress cards. Up until this point, all CFexpress-compatible cameras used CFexpress Type B cards (yes, 'B' does come before 'A' in this case!). Meanwhile, CFexpress Type A cards are smaller and slower. Crucially, Type B and Type A cards aren't interchangeable, so a camera such as the Nikon Z7 won't be able to accept a CFexpress Type A card.
