Transcend's Ultimate 64GB SDCX Card

If you are a camera enthusiast that is looking for a new memory card you should be looking for a Ultra-High Speed Class 1 (UHS-I) card to get the most from your camera. When you are shooting in 'burst' or 'continuous' mode your camera's internal buffer usually runs after a bit and you have to wait for the camera to catch up. Since you can't easily increase the buffer of the camera the only thing you can do is get a really fast memory card that allows the data to be written to the memory card from the buffer as fast as possible. The fastest memory cards today are UHS-I memory cards and on UHS-I supported devices, the cards should allow the camera to take more shots per burst and increase the frame rate (fps). UHS-I rated cards have speeds of up to 104 MB/s and when you see the logo on a product, you know it is one of the fastest SD cards available today. Today, Legit Reviews will be looking at the Transcend Ultimate 64GB SDXC UHS-I Memory Card that is available online for $62.66 shipped.

Transcend Ultimate 64GB SDXC Memory Card

This memory card is called Secure Digital eXtended Capacity (SDXC) since it features a capacity over 32GB and below 2TB (2048GB). Any card that is under 32GB is considered a Secure Digital High Capacity (SDHC) card. The Transcend SDXC Ultimate line is only offered in capacities of up to 64GB, so this is as big as you can go. Transcend does offer a larger 128GB SDXC Class 10 card (TS128GSDXC10) for $109.99, but it is not UHS-I rated and is speed rated at up to just 22MB/s read. The Transcend 64GB SDXC Ultimate UHS-I card that we have today is rated at up to 80MB/s read!

Final Thoughts and Conclusions:

If you are looking for are looking for a 64GB SDCX memory card you won't have any issues finding a card. Newegg alone currently sells 51 different 64GB SDXC cards and of those 30 are USH Speed Class 1 rated.  The Transcend 64GB SDXC Ultimate card that we are looking at today isn't the fastest available, but it is up there when it comes to performance and the price is reasonable compared to some of the other cards available. The Transcend Ultimate 64GB SDXC UHS-I Memory Card that is available for $62.66 shipped on Amazon or $54.95 shipped from B&H. We can't find any other 64GB SDXC UHS-I card rated at 80MB/s read and 40MB/s write for under $55 shipped! It's tough to stand out when there are so many cards available in the market, but Transcend offers a pretty good bang for the buck and that is the key selling point about this card.

Our performance testing found that the rated read and write speeds were right where they were advertised to be. The write speed of 40MB/s is solid and means for faster shot-to-shot camera performance. Write performance is very important to photography professionals, especially those that do continuous burst mode shooting or do high dynamic range (HDR) imaging. We used this card on a number of fairly high-end cameras and found no pause or hesitation when taking high resolution pictures as the camera wasn't waiting on the memory card to finish writing!

At the end of the day the Transcend 64GB SDXC Ultimate memory card was found to be a good deal for the price and it is also backed by a lifetime warranty if anything should happen.
