What is special about this build is that the entire Android O/S filesystem is stored in RAM before it is booted.
What does this mean? Well, RAM is faster than NAND and SD Card which in turn will make the build supe**st too
这个版本特别的地方是整个ANDROID 系统在它启动之前会加载到RAM。
这意味着什么？RAM的速度要比NAND和存储卡快多了，随之这也会让这个版本超极的快。
恩！我说的是HD2
之前HD2多系统大家都有瞭解，简直是“遍地开花” WM6.5 WP7 ANDROID2.2 MEEGO 等等..
虽然令人期待的NAND（直刷）一直处于内测没有放出..和暴雪一样跳票N久
但现在最新的ANDROID2.3 HD2都已经可以用上了 而且已经是第四版本了
（其他所谓源生ANDROID机看到2.3简直是浮云...）

而更令人吃惊的是，现在HD2已经有一种全世界首创的新手机技术！RAM-OS技术！
啥是RAM-OS技术？
就是整个OS（操作系统）都是加载在RAM里面，而不是ROM里面
这样整个系统的速度将会变成浮云级别的快速
注意！RAM加载是比直刷更快速的加载方式~也就是说HD2运行android已经比真正的android手机更加有效率
以下是RAM-OS的介绍：
What is SuperRAM FroYo?
- It is an AOSP rom with some modifications added, but kept as close to stock as possible. The only thing that is modified is the keyboard, some menu options and the launcher.
What is special about this build?
- What is special about this build is that the entire Android O/S filesystem is stored in RAM before it is booted.
What does this mean?
- Well, RAM is faster than NAND(ROM) and SD Card which in turn will make the build supe**st too! Very fast. Very very fast!
I don't understand what NAND(ROM) or RAM is!
- NAND is a slower memory type (ROM) which is designed to hold data even after the phone is turned off. This is where your Windows Mobile operating system is stored.
- RAM is a much faster memory type which is designed to hold information on a temporary basis. After your phone is turned off, the data in RAM is lost.
- Running Android on your HD2 does not touch your ROM in any way! So when you turn off the phone and turn it back on, Windows Mobile will be loaded. No changes are made to ROM.

刚刚实测了一下，速度真的很彪悍~
android的启动时间是9.7秒！
我看没有啥机器能够达到这个数量级别了吧
