Does anyone own a 633x micro SD card and can do some tests?

Hi,

i am interested in buying the I3 Surface Pro 3. Due to the 64GB SSD i want to use a Micro SD for storage. I will use one of the very fast Micro SDs (Sandisk Extreme Pro or Lexar High Performance for example).
I am not sure if the micro SD reader in the Surface Pro 3 is able to reach the highest transfer rates. Is anyone able to do some benchmarks with a 633x UHS micro SD with 64GB?

That would be nice!

Unfortunately I have not found any SP3 owner reporting anything about this card

I use Samsung Micro SDXC Pro 64GB (up to: 90MB/s read, 80MB/s write): http://www.samsung.com/sg/consumer/memory-storage/memory-card/microsd-card/MB-MG64DA/APC

With large files it reached 84MB/s read and 68MB/s write, with many small ones it drops down to 10MB/s. I left exFAT format.

I purchased the Lexar 64gb 633x micro sd card, and used it in my SP3 with 128GB version, but the speed was okay, and not spectacular. I end up returning it and upgraded to SP3 256GB because I wanted to get 8GB Ram as well. Sorry I don't have the transfer speed between the Lexar and onboard ssd drive, but I did ran the ATTO Benchmark from the SP3.

Thank you very much! The Surface is capable of using high speed micro SDs. I will wait for the first reviews of the I3 version, I think it is a true alternative.
