Take a look at this thread discussing read/write times from hacked Nooks: (link to follow in next post)
Their theory is that the higher sustained w/r speeds of class 6 & 10 cards is meaning less compared to the quicker small random r/w speeds of higher quality Sandisk cards even if they are class 2 or 4.
I would imagine that if they are right about the small random r/w speeds being more important, that this would also apply to using A2SD+ since it moves the dalvik cache to the SD card. What do you guys think? Sound logic or snake oil?
Their test samples are too small to take worth a grain of salt, but I tested my Sandisk Class 2 and its .4 MB/s write time is faster than all of the class 6 & 10 cards they've posted. So...I'm going to take the plunge and see how A2SD+ works on my phone.
@NorthernNoel, I'd love to know what speeds CrystalMark reports for your 32GB class 2 card that isn't working well. (5 iterations, 50MB, 4K QD32 scores)
