    Hello! I am new to the forum. I plan on making a dedicated final burn alpha game console. Current romset is ~12 GB.

    I just received my raspberry pi 2 yesterday. I am very concerned with all of the sd card corruption issues I’ve been reading online.

    To help prevent this, I purchased 3 items:

    Sandisk Ultra 32 GB micro SD listed on compatibility list.

    Add a start/shutdown safely button.

    Shutdown circuit (use your own switch)

    Uninterrupted power supply to safely shutdown unit in case of power failure.

    I am going to be purchasing and modifying a generic electronic enclosure for this unit, so I need my size requirements. Do you guys think the sd format is reliable enough, or should I plan on allowing space to store everything on an external USB hard drive?



    SD cards will wear out – you can’t avoid it. cards with wear leveling will be better.

    You’re on the right track, be sure to always shut the Pi down properly. Even a single time pulling power without shutting down the Pi first will corrupt files on the SD card.

    All that said, it’s not a big deal. Once you get your installation the way you want it, just back up your SD card image.



    Thank you @Roo for your response. I could not find any info as to if the Sandisk Ultra micro SD cards had file/wear leveling. I asked Sandisk. I believe the card I purchased does have wear leveling. However, I am concerned about the support team Sandisk has. The first response to my question by them seemed like it was copied and pasted, and was incorrect.


    Photo of Sandisk conversation is well under the max file size, but does not attach to post.
