I don't really have any useful advice, but I have a 16gb in my Storm and i have zero performance issues with it and the sucker is almost full of music and movies.
Maybe it's scanning all of that music/movies? The sd card shouldn't effect the storm's performance except when scanning the card and that shouldn't take that long anyways.
Only problem I have with the 16 GB card is that I need a bigger one!
I think amavit might have called it. The larger the card and more stored on it, the longer it takes to scan. While the card is scanning the phone may be a little sluggish. Did you give it a minute or so or did you just reboot right away?

That must have been it. She's flying nicely once again this morning.
There is thread somewhere here describing the same issue with 16GB cards. That's why I decided to get 8GB as this one is not slowing down my BB and works well...
There is no issue with 16gb cards after the first scan, which can take some time. And this is not just a storm issue, but it is the same on the all the BB. Have a little patience and all will be fine.
