How reliable is the sd format in general?

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.

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.
