and are around 3x faster than the internal storage in my Nexus 6. They're hitting 95 MB/s read, 90 MB/s write now. Even the Moto G has that read speed. More expensive phones are much faster... http://www.anandtech.com/show/9525/the-moto-g-2015-review/3 http://www.anandtech.com/show/9525/the-moto-g-2015-review/3 Also, I wonder what SD read/write speeds are in practice.

Not quite. A more recent chart comparing them is here: http://anandtech.com/show/9662/iphone-6s-and-iphone-6s-plus-preliminary-results http://anandtech.com/show/9662/iphone-6s-and-iphone-6s-plus-... Note that everything tested is below the 90 MB/s sequential write speed of a high-end microSD except the iPhone 6s Plus. From a review, here's the numbers on the 64Gb Sandisk Extreme Pro microSD using CrystalDiskMark: Sequential Read : 95.325 MB/s Sequential Write : 90.660 MB/s Random Read 512KB : 89.314 MB/s Random Write 512KB : 75.971 MB/s Random Read 4KB (QD=1) : 7.492 MB/s [ 1829.0 IOPS] Random Write 4KB (QD=1) : 2.441 MB/s [ 595.9 IOPS] Random Read 4KB (QD=32) : 7.472 MB/s [ 1824.3 IOPS] Random Write 4KB (QD=32) : 2.380 MB/s [ 581.0 IOPS] Note that Ars Technica is using Sequential Read/Write values on 256K which is flawed. It should be larger to be accurate.
