Our editorial take on the SanDisk 256GB Extreme PRO UHS-I SDXC Memory Card
The SanDisk Extreme PRO UHS-I is one of the most visible and recommended SD cards on the market, and for good reason. It has become a de facto industry standard for photographers and many videographers, offering a dependable blend of speed, capacity, and reliability from a trusted brand. For creators working with cameras that have UHS-I slots, this card is often the first and last one they look at. It provides more than enough performance for high-resolution photography, including burst shooting, and is perfectly capable for most 4K video recording workflows.
While the Extreme PRO is a workhorse, prospective buyers should manage expectations regarding its top-end speed claims. As is common with memory cards, real-world performance inside a camera often falls short of the 'up to' speeds printed on the packaging, which are typically achieved only in ideal lab conditions with specific readers. This is not a deal-breaker, but it is an important consideration. The card is a top performer within its class, but it will not transform a UHS-I slot into a UHS-II powerhouse. For those shooting in the most demanding, high-bitrate video formats, a faster UHS-II or CFexpress card will be necessary.
- Established as an industry-standard, widely trusted card
- Excellent reliable performance for photography and most 4K video
- Great value balancing price, speed, and capacity
- Widely available and frequently recommended
- A top-tier performer in the UHS-I category
- Real-world write speeds may not consistently reach advertised maximums
- Insufficient for the highest bitrate video modes that require UHS-II or faster media

SanDisk has an Extreme card that is stated to get up to 300 MB/s, but fails to get anywhere near that spec in our testing.
On paper, the recently released ProGrade 512GB UHS-II V90 memory card is sitting right near the top of the SDXC memory card field. Banner features include a 300 MB/s read speed and a 250 MB/s write speed and, of course, the 512GB of space for all the juicy 4K RAW footage your camera can throw at it. But how does it hold up in the field? Find out by continuing to read my review.
Media cards are not very exciting, but they are a crucial part of any production and that is why I have and will continue to review them on the site.

If you're in the market for UHS-I media, the SanDisk Extreme PRO is a great card with which to start your search.
Not only would this card already have limited utility even if it worked as advertised, it doesn’t. Not even close. Not even in the same ballpark, area code, or on the same continent.
Most microSD cards are fast enough for boosting storage space and making simple file transfers, but some provide a little more value than others.
