Kingston Class 10 UHS-I Ultimate Card 64GB

Memory cards are continuously increasing in capacity and performance, which is a good thing. 64GB of memory may be a laughably high capacity to some of you, but when you realize that our devices are producing more data than ever before, it’s not as big as you might think. Our digital cameras take photos as well as HD videos and to capture all that data, we need big memory cards to store them. We also need fast memory cards to get the best performance out of our cameras. The Kingston 64GB SDXC UHS-I Ultimate memory card is such a card, boasting speeds of up to 60MB/s read and 35MB/s write.

The 64GB Kingston UHS-I Ultimate memory card is rated at 60MB/s read and 35MB/s write. When I benchmarked the card in CrystalDiskMark using a UHS-I card reader over USB 3.0, it scored a speedy 92MB/s read and 49MB/s write. For comparison, I also benchmarked a Transcend 16GB Class 10 card, which I use in my Canon DSLR and is very popular on Amazon. That card scored 23MB/s read and 17MB/s write.

In real-world use, shot-to-shot wait times seemed shorter and I was able to take more burst shots before performance eventually slowed down.

Kingston SDXC Ultimate

All the acronyms on SD memory cards can be a bit confusing. If you’ve been keeping up, you know that SDHC stands for “high capacity,” while SDXC stands for “extended capacity.” Extended capacity cards tend to be bigger than SDHC cards. The important thing is to make sure your device is compatible with the memory card you buy.

So what is UHS-I? UHS-I stands for “ultra high speed interface.” SDXC UHS-I cards are the way to go if you’re looking for the best performance out of a high capacity card. UHS-I is the newest technology and unless you have a very new camera, your camera’s card reader may not support UHS-I. Make sure to check with your camera manufacturer for compatibility before you pick up the UHS-I card. However, the Kingston Ultimate is backwards compatible, so even if your camera doesn’t support UHS-I, as long as it still supports SDXC, you’ll still be able to use it.

The Kingston 64GB SDXC Class 10 UHS-I Ultimate (SDA10/64GB) memory card is unquestionably fast and big. Its performance may be overkill for some users, but if you’re looking for high performance at a very reasonable cost, you should strongly consider the Kingston Ultimate memory card.

Available from Amazon.com for about $63.
