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

Product Information

Consistently fast read speeds and large capacities make this a good choice for recording video at higher resolutions. 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. 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.

Pricier than rivals, this Lexar card offers consistent read and write speeds fit for both sports shooters and 8K filmmakers. Next on our list is the Extreme Pro SDXC UHS-1 from renowned SD card manufacturer SanDisk. As part of a team of manufacturers that came together to introduce standardization of the SD card market, we’re getting a good, reliable card at a decent price.We test microSD cards in a high-speed USB microSD card reader, connected to a laptop via a USB 3.2 Gen 2 Type-A connection. We use a combination of the CrystalDiskMark and AS-SSD benchmarks to test both sequential read and write speeds and random read/write speeds. 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. For the average photographer who needs a rugged SD card for a reasonable price, this PNY option is a hard one to beat. Available with up to 1TB of storage capacity, this is a versatile and good value card for a wide range of stills and video shooters. The best microSD cards to buy in 2023 1.

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.Card classifications like V30 or U3 are just categorizations of these speeds. There are three main classes: Speed Class (denoted with a number in a circle), UHS Speed Class (a number in an open beaker-like icon), and a Video Speed Class (V followed by a number). The numbers indicate the minimum writing speed when put under data transfer. Speed class is categorized into Class 2 (a minimum write speed of 2MB/s), Class 4 (4MB/s), Class 6 (6MB/s), and 10 (10MB/s). Choosing the best one for your camera depends on your camera's resolution, buffer size and burst shooting speeds. An additional clue is the UHS Speed Class rating, which is U1 or U3. U1 means it can write a minimum of 10MB/s (like Class 10), while U3 pushes the write speed up to a minimum of 30MB/s. More interested in shooting video? The Video Speed Classes are V6, V10, V30, V60, and V90, with V6 suitable for standard definition video recording and V90 capable of 8K video capture. 4K UHD video recording will require a minimum of V10 ideally, and HD video can utilize V6 or below at a push.
