A class 4 is considered plenty for smart phones and similar electronics. Though our phone, as most newer phones, can take up to a class 10. Higher the class - the better the transfer speeds.
Class 10 is supposed to have a minimum of 10mbps and a high of 22mbps. In general the class numerous indicates minimum transfer speed. The better the brand, the better the sustained read/write speeds. Though class speed does not mean it will not go over the high end of it's transfer rate. Some class 6's (6mbps min transfer speed) have topped out around 30mbps. Again, the better the brand, in general, the better the 'past minimum' speed performance.
Though class 10 cards are a bit more expensive, and not obviously practical, unless you were getting it for having the OS run on it, like cm7 :), but even then, as most people don't have their cm7 running on a class 10 sdcard and no one is complaining about slow performance.
I'd recommend putting the money towards a lower class 64gb card. As long as you format it with fat32, and ideally 32bit sectors, the phone will recognize it, giving you a stupid amount of available storage.
