The SanDisk 128GB Extreme PRO SDXC UHS-I Memory Card offers read speeds up to 200MB/s, as noted in the manufacturer's product description. This is supported by SanDisk's QuickFlow Technology, which is designed to speed up data transfer.
Our research suggests that many folks are happy with how quickly they can read and write high-res photos and 4K videos using this card. That being said, there are some who have mentioned that it doesn't always hit that 200MB/s mark, depending on their gear and what's being transferred.
In terms of professional reviews, they generally back up the manufacturer's speed claims, emphasizing the card's reliability in handling fast-paced tasks like 4K video shooting and burst photography. If you're looking at getting the most out of this card, it might be worth pairing it with the SanDisk Professional PRO-READER SD and microSD for optimal speed performance, though keep in mind, that's an extra purchase.
Overall, if you need a card that's built for speed and stamina, especially in demanding shooting situations, this one is definitely a solid choice.
