Installing Android ROM on a HTC HD2 on the SD card - Performance impact? I'm currently running Android on my HD2 using the internal memory. However I'm having terrible issues with the memory filling up and I can't seem to solve it. I considered installing Android directly onto the SD card, but was told by a friend that it would slow down the OS so bad that it would hardly be possible to use.

So my question here is quite simply; will there be much performance impact by running Android from an SD card?



Adding bounty now, due to lack of patience.

Quite a few people dual boot Nook Colors (internal vs sd card).

Take a look at this xda thread on running CM7 on the sd card (for the Nook Color) and this thread about booting from sd card performance.

In short, it really depends on the read/write abilities of the sd card you use. A crappy sd card is going to give crappy performance.

(Sorry for the specifics to Nook Color, but in general, it should be similar)
