Storages
There are ram, flash memory and sd card. Generally, ram is the fastest and sd card is the slowest.

Common partitions

• splash1
• boot
• kernel
• recovery
• system
• essential software
• For example, CyanogenMod is installed to this.
• Generally speaking, this is write-protected.
• cache
• data

Complaints about desktop environments on Arch Linux

GNOME
Though I installed gnome in accordance with official wiki on Arch, GDM did not started properly. I could not find a solution.

MATE
It took long time to load components after log-in. I cound not find a solution.

KDE
It worked well. But it is very feature-rich to me.

XFCE
It worked well. WFWM has the ability to tile a window automatically when it is moved to the edge of the screen by resizing it to fill the top half of the screen. This was annoying to me. But finally I got a solution from XFCE wiki on Arch website.
