[Gen8 Android Development] p0rk burn:
A lot of weird issues that popup while running Uruk Droid from the SD card may actually be the result of the card itself not being able to handle the constant read/write. Even if the card is labeled a class 10 you may get worse performance than the stock. I know, I used a class 10 for a week or two and it was essentially unusable, so I moved Uruk to the internal storage.

Use this thread to post your experiences and test speeds for the various SD cards. If you can, use $auron's method for some uniform baseline, but a general description of the experience is important because some of the issues don't seem to be captured by a speed test. Of course, please list the card's make and class as well as size.

Please use $auron's method in post 3 for testing.

Perforce feeling: Ok - bit better than internal system on average, except Media Scan which takes FOREVER (may not be due to card - it has no media on it whatsoever)

I'll dig up numbers again specifically, but a previous test on the vfat partition rendered results in the mid 6MB/S ballpark if I remember correctly. Kingston is known for being a bit on the slow side of things.
