[TIP] Defrag phone storage - Sony Xperia P, U, Sola, Go

Hello Everyone !
Last week i was trying different ways to mount our phone storage ( internal as well as card ). What im about to share is the result of some experiments done at that time.
This is not a guide exactly, as many of us know the steps done here, but still, i take no responsibility of any type of problem you face.Please ask for help if you need.
for more information : Read this.
When i checked my internal storage, it was 72% fragmented !!!
so i thought may be there are others who haven't formatted internal/external storage for a year or above, thus leading to heavy fragmentation.
here it is :
method 1: (also applicable for card storage)
take backup of all data and format. That should solve it !
method 2:
i recommend using 360 security app(with root access) first.
let the app scan your phone, it will find app cache, trash and user data in your phone. but first uninstall unused apps and delete some data that you don't need. you can always copy it back if you need it.
clean all, including empty folders (it will increase simplicity of your storage).
How to Mount Internal Storage as USB DRIVE :
1. Reboot into CWM
2. Connect phone to a windows PC (prefer win 7)
3. Go to "USB mass storage"
4. Select mount sd card.
5. You should see your internal mounted as removable mass storage drive.
6. Enjoy unrestricted access to your internal drive.
--------------------------------------
All right guys, i dont know much about the ssd, but if it is not necessary (even at > 50% of frag-level ), please tell me.
Thank you !

And here I am, thinking that we are using the EXT file system. :|

at least Samsung uses ext4, i think Sony does that too ...

Samsung uses their own filesystem in the newer devices.
And I think Sony uses ext4. But the thing is why would we need defragmentation if it's ext4. The files aren't accessed as in windows. Of course that windows will find disk errors and that there is a need if defrag. But the way Linux works, do we really need that?

---

file access is not the issue. i think the way ext4 manages writes makes all the difference.
ext3/ext4 avoid fragmentation of data and the way they store data, they can easily manage new read/writes without decreasing performance.
but even ext4 gets some issues, i found after some googling that when free space is less than ~15%, ext4 does not get enough room to swap things around. that fragments the drive heavily, thus the issues.
in that case, defragmenting might do some good.

Oh yeah, on low space. Well on my U from 4GB I usually have around 2.5GB free so I guess I'm safe for now.
Btw the fragmentation usually shows losing performance when accessing libs and stuff. But that doesn't apply to us.

i had only 500mb free some time ago, so i did defrag the internal at that time(72% fragmentation), but now i have 3 gb free ! :highfive: .so its same for me ...no need !

Internal storage (/sdcard) uses FAT32 file system, the data partition uses ext4 file system.
I know that defragmenting a flash drive is useful only to cause more wear and tear.

---

Are you all insane? You can't defragment flash drives!
That slows it down and eventually will ruin it.

If sdcard uses fat32, then it should be defragmented....otherwise its fine...
One doubt though, internal is named sdcard too....
You mean external storage, right?

so we shouldn't need to defragment internal or card.... Right?
Well I wasn't aware of this...

Internal storage use FAT32 filesystem, external storage use FAT/FAT32/exFAT.
Both are flash drives and shouldn't be defragmented.
