SDHC should be OK (must be 32GB or lower?)
I just ran AndroBench on my internal SD Card with fsync disabled - I'll run it on my Sandisk UHS-1 Class 10 64GB SDXC in a minute
As you can see they are approx the same as the external data setup gives the same benefits as internal + fsync without the dangers of disabling fsync.
would a reinstall possibly fix this?
how I plan to reinstall..
reboot to recovery, advance wipe everything (same options, will not do anything about fsync)
then reinstall cromi 5.3, go back to home
then flash 5.3a patch, then reboot
would that be okay? i am scared to brick my device.. or how should i go about it? i have copied my files to my computer and do not have many apps, i use my tablet solely really for studying.. so a total wipeout really wont bother me..
BTW I tried the benchmarks without fsync disabled and got very similar to yours so it looks like the card controller is rubbish on the transformer as well. But the rom should feel zippy even so.
If you want to wipe your data2sd partition you'll need to run the mount zip first.
Why don't you just try a nice clean install on internal first - let's get that up and running.
