I am glad that Samsung Galaxy S III supports micro SD card up to 64GB. So I can have excuse to buy 64GB SanDisk Ultra microSDXC UHS-I Card (Class 10) and put on it. 64GB SanDisk Ultra microSDXC UHS-I Card (Class 10) can achieve speeds up to 30 MB/s (30MB/s read speed; write speed lower), has class 10 speed rating and UHS Speed Class 1 (U1) enabled. Besides, it is also water-proof, temperature proof, X-ray proof and shock proof. How does it perform? Let’s find out…
64GB SanDisk Ultra microSDXC UHS-I Class 10 Card manages to get read speed of 40 MB/s sequentially. 10MB/s over the 30 MB/s set by SanDisk. Cool… However, the sequential writing speed is much much lower at 13.92 MB/s. But still fulfills as a class 10 card.
As expected, Samsung Galaxy S3 micro SD card slot is not UHS-I enabled. So 64GB SanDisk Ultra microSDXC UHS-I Class 10 Card performance is lower on Samsung Galaxy S3. Only get 17.94 MB/s sequential reading speed and 9.35 MB/s sequential write speed.
64GB SanDisk Ultra microSDXC UHS-I Class 10 Card is a nice addition to your smartphone. It has high reading speed. This will surely shorten file transferring time.
