Also, although still respectable, the time taken to transfer images to a computer is a little longer than with some other cards. For my first test of the 64GB SanDisk Extreme PRO 300MB/s SDXC UHS-II, I popped it into the 45.7MP Nikon Z 7II and set the camera to shoot at its fastest rate (10fps) with the focusing set to manual to rule out any focusing delays. When the camera was set to record 14-bit uncompressed raw files I was able to capture 38 images in a continuous sequence - putting it on par with the PNY X-Pro 90 SDXC UHS-II card and ahead of the Manfrotto Professional SDXC UHS-II card. I’ve tested the 300MB/s version which is available with capacities of 32GB, 64GB and 128GB. The 32GB card is an SDHC device, whereas the 64GB and 128GB cards are SDXC devices.

Also, despite chalking up impressive read and write speeds of 252MB/s and 207MB/s respectively, the SanDisk Extreme PRO 300MB/s SDXC UHS-II proved to be one of the slower cards when it comes to moving files onto a computer. The shortest time I was able to transfer 100 Fine* Jpegs and 100 14-bit uncompressed raw files from the Nikon Z 7II (adding up to 9.7GB), was 2 minutes 37 seconds - that’s minute slower than the Lexar Professional 2000x SDHC/SDXC UHS-II.As usual, the SanDisk Extreme PRO 300MB/s SDHC/SDXC UHS-II cards measure 24 x 32 x 2.1mm, which means they slip neatly into a camera or card reader’s slot. After heavy use, the 64GB card that I have been using shows only slight signs of wear on the label. Use our super easy product search to filter down and find exactly what you need.

Switching to record Fine* Jpegs boosted the burst depth significantly to 65 images, but that’s someway behind what was possible with the Lexar Professional 2000x SDHC/SDXC UHS-II, Kingston Canvas React Plus SDHC/SDXC UHS-II and PNY X-Pro 90 SDXC UHS-II cards. Shooting Fine-quality Jpegs increases the burst depth again, but at 78, it’s still behind the other cards I’ve tested recently, only beating the Manfrotto Professional SDXC UHS-II card.
