With the newest version of Android, Froyo –aka Android 2.2, many of you might wonder.. when should i move an app to SD? Well lets explore a little deeper into this very question by examining some of the advantages and disadvantages of apps to SD.
- Virtually unlimited install of applications (depending on how big your SD card is + your internal storage)
- You can speed up your system again. When internal storage is holding a lot of applications, your system can start slowing down because yaffs (androids internal file system – yet another flash file system) starts slowing down when it has to go through pages and pages to do reads and writes.
- Could be slower than internal memory. Internal memory and cache is always known for its speediness. Apps to SD can make your applications perform slowly–this is usually only an issue on lower class cards (the development community recommends only using apps to SD on a class 6 SD card)
- Apps not available while phone is mounted to your computer. When you mount your SD card to your computer to add/remove/edit files, your applications that are currently on your SD card will not be available for you to use.
- Life of your SD Card shortens. It has been proven that using apps to SD can shorten the life of your SD card. micro SD cards aren’t made to withstand that many reads/writes in its life. With all the reads and writes that are required to run an android application from the SD card, the life of your SD card could shorten.
Despite the disadvantages, if you follow a few certain guidelines you can benefit from using apps to SD. Here are some of the situation where you should benefit from using apps to SD.
When should you move an app to sd on froyo?
- When you have an application or game (that isn’t deeply integrated into the OS) that isn’t one of the following: Widgets, Input methods (keyboards/voice input), Account Managers, Device administrators, Live wallpapers, and Live folders.
- When the application is too big for your internal storage. Applications such as Google Earth (~30MB) take up a hefty amount of your internal storage, moving those to your SD card can make it so you can enjoy those larger applications and still have your needed applications (widgets, etc) to still fit in your internal storage.
- Games that you don’t play too often. Moving your games that you won’t be using while you’re mounting your phone are a great candidate for being moved to SD.
