There are maybe a dozen nearly identical choices on Amazon right now. This one (which I have not personally used) supports SDHC and SDXC cards as well as UltraDMA IDE modes, so it ticks the necessary boxes. It’s so light that I wouldn’t expect the adapter to slide out of the port - those 44 pins have some friction.

If 10 MB/s write speeds of a class 10 card aren’t fast enough for you, there are 30 MB/s, 90 MB/s, and even 260 MB/s cards. The read speeds of these cards will all be much faster than their write speeds.
