Should it really take this long?

Should it really take about 2 hours to transfer on the same drive controller but different 'channels' (PCI expansion card) 150GB of data from Drive to drive? I calculated this to be about 21MB/s, doesn't this seem a bit slow for a 200GB Seagate 7200RPM drive and a 400GB Seagate 7200RPM drive? I have a promise ATA100 drive controller.

How is the data being copied? If it's going from filesystem to filesystem, and you've got any significant number of small files, 21 MB/s isn't too bad an average. If you were copying blocks I'd be a little more worried.

Both are NTFS and these are quite large files too! Thats why I'm so worried. The data should be relatively sequential since it's not only completely and utterly contiguous but I'm copying all of the data so I dunno.

Did it take that long, or did windows think it was going to take that long at the time?

Windows can't calculate transfer times to save its life, from my experience.

I believe it would be correct due to the file being contiguous. Windows does an ok job of calculating times it takes but usually falls short due to fragmentation.
