The right memory card can mean the difference between unlocking all of your camera’s best features and being stuck with slow frame rates or low-res video and photos.For recording 4K 30p video and shooting bursts of photos at up to 8 frames per second, the Lexar Professional 1800x v60 UHS-II SDXC card is your best option. In our tests, it delivered consistently excellent read and write speeds, and it’s more affordable than any other card we assessed in its class. If your camera is older or your needs are less demanding, you can save some money by opting for the SanDisk Extreme V30 UHS-I (128 GB).If, on the other hand, you need to capture faster bursts or shoot more demanding video resolutions or bit rates on a Sony camera, we recommend the Nextorage A1 Pro (160 GB) VPG400-rated card. If you own a camera from Canon, Fujifilm, Leica, Nikon, Panasonic, or any other brand that uses Type B, you should go for the SanDisk Extreme Pro (256 GB) card.
