SanDisk Ultra 64GB SDXC Memory Card, Up to 120 MB/s, Class 10, UHS-I, V10

Product Information

The Transcend did superbly in its speed tests, excelling the claimed write speed (180MB/s) with a whopping 224MB/s, but falling slightly short on the read speed with 224MB/s. Overall, that makes this card an impressive buy at a reasonable cost. This card is ideal for high resolution, rapid-fire stills photography and 8K video, with 4K and HD video being recorded comfortably, too.

SD cards for 2023: top memory cards for your camera The best SD cards for 2023: top memory cards for your camera

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. The Sony SF-G Series Tough UHS-II stands out from the crowd by bringing some extra ruggedness claims. It comes with a premium price, but that isn't surprising considering its build. Branded as dirt, dust, water, and grime-proof by Sony, it’s also purported to be 18x stronger than standard cards thanks to a unique resin-moulded design, which can be felt easily in the hand. It also has a noticeable protective protrusion at the rear. Despite being rated faster than the Lexar 1000x, the Lexar Professional 1066x actually uses the slower UHS-I interface. This turns out not to be a big deal, though, as we still measured sequential read speeds of up to 157MB/sec and write speeds of 80MB/sec on our 64GB sample, with the faster 128GB to 512GB versions capable of over 120MB/sec. In our real-world tests, we found that the read and write speeds fared significantly better than other cards in its class. It only dipped 19MB/s shy of the claimed write speed at 241MB/s, making it ideal for larger data transfer such as 4K or 8K video recording, with the read speed only lagging slightly behind at 253MB/s. For stills, this would benefit sports and wildlife photographers, or indeed any discipline that requires rapid bursts of high-resolution photographs. It'll also work nicely for filmmakers needing to capture 4K and 8K on cameras, as it’s one of the fastest in this guide, as shown by its V90 classification.The best microSD cards to buy in 2023 1. Integral Ultima Pro Premium High Speed: Best-value microSD card at higher capacities You’ll pay more for its durability, but this Sony SD card is built tougher than most and also delivers solid read and write speeds. For added peace of mind, the card comes with a warranty direct from SanDisk giving you a lifetime guarantee should any fault arise (and by lifetime, they mean 30 years). Not bad, considering we probably won’t even need SD cards that far into the future. It didn’t match claimed speeds in testing, but this is still a fast, reliable card for pros who are happy to pay for performance.

SanDisk Extreme PRO 64GB SDXC Memory Card up to 170MB/s, UHS

Our SanDisk Extreme SD UHS-I V3 tests saw write speeds live up to its claims, matching them almost exactly at 71.6MB/s. But as with most other cards on this list, the read speeds leave a bit to be desired, coming in at almost half the claimed speed, 71.6MB/s. All can be forgiven, though, bearing in mind the extremely low cost of these cards, especially while still offering such high capacity to users at up to 256GB sizes. These standards cover the speed of the interface between the microSD card and your device (or memory card reader), as this can also limit the maximum speed of data transfers between the two. UHS-I has a maximum speed of 104MB/sec, and you’ll usually see a Roman numeral “I” beneath the U1 logo. UHS-II takes that up to 156MB/sec (with data transferring in both directions) or 312MB/sec (with data transferring in only one direction). 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. For the average photographer who needs a rugged SD card for a reasonable price, this PNY option is a hard one to beat. With the right card reader, the Professional High-Speed version of the Ultima Pro can be a serious speed demon. With Integral’s own high-speed card reader, we were disappointed with its 99MB/sec and 88MB/sec sequential read/write speeds, but in a third-party high-speed reader, we saw read performance leap to 173MB/sec, with sequential write speeds of 139MB/sec. That write speed is the fastest we’ve seen from a UHS-I card.What’s more, this card comes into its own on random read/write speed tests. Here, we saw the fastest performance we’ve seen from a microSD card, reaching speeds of over 12MB/sec. Other cards from Lexar, Kingston and Samsung are catching up, but this is still the speed king for app and game performance. Given that it’s only slightly more expensive than the basic Ultima Pro, that makes it one of the top options for smartphone or Switch use. Consistently fast read speeds and large capacities make this a good choice for recording video at higher resolutions. While the higher capacity cards increase in price exponentially, the 633x appears in sizes as small as 16GB, making it suitable for a wide range of photographers and videographers alike who require all kinds of capacities for casual or professional use. We found its write speed to be a little slow compared to other UHS-I cards in this class range, but it’s good value for money and the V30/U3 class listing means it’s still suitable for up to 4K UHD video recording. Matching the claimed read speeds almost exactly at 254MB/s, the 1667X does well when compared to the claimed transfer speeds. Write speeds did drop by about 20% to 101MB/s, which is similar to or better than other cards in this roundup. Consistency, fast speeds and a limited lifetime warranty make the 1667X a very desirable option for creatives who need to capture scenes at higher resolutions.

On top of this, most cards now have a “V” (for video) rating, going from V6 all the way to V90, indicating write speeds of 6MB/sec to 90MB/sec. You need a V30 card to shoot 4K video at speeds of 60 to 120 frames per second, while V60 is the base level for shooting 8K video at 60fps. V90 is theoretically capable of handling 8K video at up to 120fps. However, given that only a handful of professional-grade cameras can offer that, and that they tend to use the larger CFexpress 2.0 cards for storage, this isn’t what you might call a must-have. We think the best SD card for most photographers is the Transcend SDXC UHS-II U3, thanks to its incredible transfer speeds and impressive durability. That said, a more affordable alternative is the SanDisk Extreme Pro SDXC UHS-I, while the PNY Elite Performance SDXC is ideal for buyers on a budget. Offering supreme write speeds and impressive durability at a decent price, this is an ideal card for shooting high-res stills or 8K video.

Sequential speeds matter most for copying large files and sustained data transfers, as they do when streaming 4K video to a phone or tablet, or recording 4K video from an action cam. Random read/write speeds are more important if you’re running apps or games from a microSD card installed in a smartphone or handheld gaming device.

SanDisk Ultra 64GB SDXC Memory Card, Up to 120 MB/s, Class 10

On the face of it, the SanDisk Extreme Pro seems overpriced. This U3, V30, UHS-I card is significantly more expensive than the Samsung and Integral competition at most capacities, and when tested on our SanDisk ImageMate Pro card reader it wasn’t any faster, at least on sequential read and write speeds, which were 96MB/sec and 85.4MB/sec respectively. Thanks to the UHS-II technology in the 2000X, we can rely on this card for fast read and write speeds. Though slightly more expensive than its competitors, the Lexar name is known for reliability and consistency in performance when it comes to memory cards.You don't have permission to access "http://www.argos.co.uk/browse/technology/mobile-phones-and-accessories/microsd-memory-cards/c:30154/capacity-(gb):64/" on this server.
