Is the Card Only 48 MB sec Maximum Read / Write Speed
I see the specification list this card as 48 MB sec maximum Read and Write speed but the SanDisk website and this Model of the same card listed on Amazon; SanDisk Ultra 128GB Ultra Micro SDXC UHS-I/Class 10 Card with Adapter (SDSQUNC-128G-GN6MA) [Newest Version; have the specs as up to 90 MB sec Read / Write. What is the difference in the cards? Is this BestBuy Card UHS-3 and slower?
