If you googled this you already know the TF201 doesn't have the greatest performance in terms of IO. However there is some good news. There have been tweaks made that you can apply now as well as there is some indication that ASUS and Devs are coming together to put down some fantastic numbers in this arena.
This means the overall speed of the TF201 should be greatly improved. I wouldn't imagine top throughput speed to be amazingly greater but SQLite should be much faster. About 10X or more.
