Hey Everyone,

I recently discovered the wonderful program 'Directory Bind' which basically lets you redirect a directory from /sdcard to somewhere else.
(i.e. you external memory card!) This is fantastic since some games (Like Bard's Tale) consume a gig of /sdcard space and apps2sd doesn't work.

I also discovered that 'sd tools', whch allows you to test read/write to a directory allows specifying any directory, so can select a directory in /sdcard and test the internal memory speeds.

I noticed, for my Lexar Class 10 card (LSDMI32GBSBNAR), I got 10 MB/s write, and 20 MB/s read.
For my Note 1, the internal memory has only 5.4 MB/s write, but 47 MB/s read (!!!!)

I am now very curious how the memory speeds of the Note 2 are, and also what the speed of the SD interface of the Note 2 is.
But it's nice to get confirmation that games/whatever should load considerably faster if you keep them on internal memory.

It's an xda app:

http://forum.xda-developers.com/show....php?t=1410262

Some notes:
1) First: Go into settings -> default data path and change it to: /mnt/extSdCard/
It is currently the old ICS directory of /sdcard/external_sdcard


2) Simple Instructions:

First, find a big directory with your data.
Run DiskUage, select 'Storage Card'. Note the directory pattern, i.e. Android/data/com.ea.deadspace_na

Menu -> add new entry
Menu -> data transfer assistant
Find the directory you used above.
Hit 'Add'.

Hit the disk to activate the mount. It should turn green.

Now rerun DiskUsage.
A) You should see a new 'disk' which corresponds to the directory you just moved.
B) Check 'Storage Card'. You probably need to 'Rescan'. You should have more memory now.

Now try playing the game or whatever you just moved.

You would not believe it but finding your post here has saved me hours of anguish! The one flaw I found in the Note II was the crazy storage problem. Now resolved. Thank you so much!

By the way, I highly recommend, before doing a nandroid/CM backup, to turn off the binds.
Since the data is already on your external card, there's not much point in backing it up again.

Not to mention: if you do a restore you might exceed your internal memory.

Hello there

Is there any application besides Directory Bind that does the same operations in a more user-friendly way?
Thanks a lot
