If you are talking about running CM9 off of an SD card, and the 4GB worked well and the 16 GB card kept giving you problems operating, then you have discovered what many before have found. Not all SD cards are created equal. There is a whole thread here on XDA that talks about how different brand and class cards make a difference in running ROMs on the nook. Size does not really matter, but brand and class do. They have found that SanDisk class 4 cards work the best, and cheap, so called higher class cards are the worst. The nook requires cards that give good performance writing many smaller files and higher class cards like 6, 8, and 10 do not perform well at that task. I bet your 16 GB card is a higher class or some no-name brand.
