general SD card read/write problem

[Dmitry Shalnoff]

Hello Everybody,

I have a periodically appeared problem with SD card writing/reading functionality. I has several cards to try and found some correlation with size and speed type of the card. '

Problems are appers when I'm trying to write intensively on the card. Usually on the next boot I found filesystem corrupted and cant' mount card anymore till I fsck it (with predictable files damage) or reformat. 

generally it's looks like 16GB cards almost 100% cases have problems. 
and as I suppose 4 class cards more prone to problem than class 6. 

Question is simple: Is my suspicions are correct (concerning class and card size)? what is general recommendations? Who has any good/bad experience with different types of cards?  

I know about this topic http://wiki.openmoko.org/wiki/Supported_microSD_cards , but it's doesn't looks like relevant tutorial to buy fail-safe SD and obviously this problem doesn't rely on brand name too. 

thank you beforehand for any help,
Dmitry
