The U3 and V30 ratings really deliver fast read and write speeds, which makes transferring large files quick and seamless.

Review: Reliable and fast memory card for photos and 4K video - I bought this SanDisk 256GB Extreme PRO SDXC card for my A6700 and it's been a game changer. The write speeds are fast enough to handle burst photo shoots and 4K video recording without buffering or dropped frames. I've used it on several shoots, from family events to travel, and it has never failed or corrupted my footage. The large 256GB capacity means I can shoot all day and not worry about constantly swapping cards or running out of space. It also seems to handle temperature changes and occasional moisture exposure without issue, giving me peace of mind when shooting outdoors. If you need a reliable, high performance SD card for photography or videography, this one is worth the investment.
