SD* card only comes in only one form factor* (aka physical size), so the "size" you're referring to is storage size. And yes it does, smaller sizes are usually faster. But is it fast enough to not get a larger size? No, if you find a good price on larger size, get it because you might need extra space for maps. What's important is the speed rating of the card. Higher the Class**, the better the "performance." Also my experience tell me to not fill the card to full capacity, stop at around 90%.

* I'm assuming you're referring to SDHC for 4GB or higher
** The Class rating is a guideline not a certification, so one manufacture Class 10 might be slower than another at Class 8. I recommend sticking with name brand that you find reliable and beware of counterfeits. Case in point, Samsung EVO; if it's originally from Samsung, it's one of the best card but there are many chinese counterfeits on ebay.
