I don't think you'll get close to 20MB/s.

For OpenBSD you'll get the best speeds from a card which supports
multi-sector IO (6MB/s or so?). The Sandisk cards I've seen do,
many others are 1-sector only and a lot slower on OpenBSD (2MB/s
or so; looks like DMA is disabled in those cases - I'm not sure
whether that's necessary, and doesn't apply to all OS, but it's
the way it is at the moment).

I've been buying 2GB cards recently, 1GB weren't much cheaper
and 4GB cost a lot more (this probably varies according to local
conditions!).
