"According to SanDisk, the 32 GB and 64 GB models provide read speeds up to 80 MB/s and write speeds up to 50 MB/s. The 16 GB model provides read speeds up to 80 MB/s and write speeds up to 30 MB/s"
nothing to see here. SanDisk Extreme Pro microSDHC have 95Mb/s read and 90Mb/s write
I really could care less about this as much as I want larger capacity on these cards. At CES and other tech expos; it has already been shown that they can put 2TB on MicroSDEC cards. I am running android devices that support the EXFAT format and we should have seen at least 128,256 and 512gb versions of these cards already.
Sandisk is just soaking up suckers with these low capacity cards.
too bad the galaxy s4 is the only phone that supports the uhs-1 transfer speed. So in every phone but that 1 even g note 2 it will be 15MB/sec transfer rate.
