Reply to Storing music on SD memory cards

I have a question regarding SD (Flash) memory cards -

Would saving music to an SD card in my mac book pro load songs faster than off the HD?

I have a ton of music on my HD and in iTunes and it is getting to be quite cumbersome and messy. Too much old music, samples and low quality remixes that I would like to keep, but dont want to deal with and sort through at gigs. I would like to have all of my high quality tracks that I use for gigs in folders on a 32 gb SD card. that way I have everything I need in one place. I know SSD's will load music a lot faster, but is the SD port in my mac able to load faster than the HD?

Also if anyone knows of a nice 32GB SD card (class 10) to invest in please let me know. It seems there are a ton of options, but lots have mixed reviews. My budget is about $30 shipped

Thanks guys
