IMO when choosing a memory card four things are important:
3) in-camera performance
4) performance with card reader
In 1, 2 and 4 SD(HC) wins by a very large margin.
For 3) it's not very clear because there are no timings for the S8000fd yet.
But the official camera specs tell a lot about the performance.
In continuous mode you can shoot pictures at 0.5 frames/s. Assuming the average picture size of a 8MP camera is 3MB, the transfer rate is 1.5MB/s (=10X).
You can record hi-res movies at 18.7 minutes per GB which is less than 1MB/s.
So I think it's safe to say that the S8000fd is built for slow cards. So card performance with this camera doesn't really matter especially because it has a pretty large buffer.
The card I was referring to is the A-Data Class 6 4GB SDHC:
Class 6 is the highest speed rating of SDHC cards. It means that the minimum sustained transfer rate is 6 MB/s which is 50% faster than the fastest xD card.
So yes, for $24 you can buy a 4GB SDHC card which is at least 50% faster than any xD card.
SD cards are indeed not created equally but look at these performance charts:
The performance differences between xD and SD(HC) are huge.
Sure, SD cards which are just as slow or even slower than xD cards do exist but I don't see any reason why you should even consider buying them. Just as I don't see any reason why you should consider buying xD cards when your camera supports SD(HC) cards which are superiour in almost every way.
