Read speeds aren't as fast as UHS-1 cards

Transcend was kind enough to lend us a 64GB Class 10 SDXC card for review.  Like other SD cards with greater than 32GB of capacity, this is a next generation SD card where the letters ‘XC' stands for "eXtended Capacity".  The SDXC format allows for capacities of up to 2TB, but due to the current

Fastest sequential write speed we have seen with an SD card; Read performance also very fast; faster than any of our SD card readers are able to handle; Very large capacity for an SD card; making even a 50GB dual-layer Blu-ray disc look ridiculously large in comparison; Less than half the price of

Write performance sharply falls off with free space fragmentation; Unable to keep up with a 34Mb (4.2MB/s) real-time recording with significant free space fragmentation; Poor write performance with individual files; especially with files smaller than 10MB; Card only meets its Class 10 rating with

I'm using this card for extra storage on my lap. No problem whatsoever.

Extra storage; good price

This product just don't have the speed for HD camera. Now taken still picture it does fine.

Worked as expected. Provides lots of space for 2.5 photos + Raw data in my new Cannon SLR. Down loads to my new 2 TB portable hard wit no problems. Quite satisfied with quality and price.

I ordered this Transcend 32 GB Class 10 UHS Flash Memory Card TS32GSDHC10U1E during an Amazon Lightning deal. Prior to this purchase, I have used over one dozen memory products (CF/SD cards and USB drives) from Transcend, and have good experiences with this brand.

I have had the card for a few weeks and it has been great. 64GB is a TON of pics and the speed is dynamite for HD movies as well. Write speed keeps up with the camera, even with my less-than-professional (ahem) capabilities !

Great price, holds pictures very well. Lots of space should hold an entire expedition on one card and at an affordable price. No problems syncing it up to camera, goes right in and adapts easily.

works great.. I had problems with SanDisk.. seem they had format problem with early production runs.. I always like Transcend products..

Great marvelous woopie These super Ultra high speed cards are the real thing!!!!! They are true Class 10 and with my testing software performed true 40mb+ per second speed. Taking photographs of the stars I need the fastest cards I can buy.
