I got the Roku 3 and I'cant find the info in the book that came with it saying what size and type of micro SD cards it supports. I'm getting ready to order some stuff from amazon and figured may as well throw in a memory chip to save on shipping. Dose any one know what is and what not compatible.
EDIT: Formatting in a computer is also a waste as the Roku will format the card for itself.
There are more reasons one would want a larger sdcard than for games. There are channels such as Vudu that allow you to download movies or shows that you own or rent. Reasons one would ever wish to do this are those that have slower internet, such as my In-laws who live far out of reach of cable or like speed Internet services. I bought them a roku because there tv options were very slim. Since they have slower side dsl they can rent a movie or buy on vudu and stream in sd just fine..but if they wish to watch something in HDX the file size is far larger. They can simply download it when busy with other things and then watch it at their convenience without streaming at the much higher quality. The larger cards makes it so one can keep more than a few movies downloaded if they may watch them often.
