This is interesting because I was searching for an SD Card speed topic as I was curious to know whether the Ultra High Speed SD card that I bought was worth the money or whether I wouldnt get any higher speeds than Class 10.
Now that I've stumbled on this topic it will make me want to test it each week to determine whether any corruption has occurred or loss of speed or data. I've only had it since April the 4th so far and nothing wrong has happened but I will report back here if I do find something I dont like regarding the SD card.
I tested the speed with the program Android Tuner and I'm happy with the results. The first picture is the Android internal SD card speed with associated cache sizes and the 2nd picture is the Ultra High Speed external SD card with associated cache sizes.
If anyone knows of any SD card speed topics it would be good for me to have the link, as the forum search feature doesn't let you include the letters "SD" together because it says they're too commonly mentioned.
*Duplicate of a post I made before*
I've just used it to restore system backup and ive restored at least 4 times already so there has been some reading and writing access with some large file sizes, but not sustained reading and writing access like listening to MP3's or watching videos.
So far it seems good, and I'm looking to take advantage of the read speeds of the card by installing an internal2external sd mod, so then there will be more sustained reading and writing on the card. I always use the "cache to sd card" option in Dolphin Browser.
