Probably the reader/card combo, mostly reader. I did some testing of
read speeds, in MB/sec.:
2GB 4GB
Reader UII ExIII
-------------------------------------
Built-in in desktop 2.6 2.6
Old All-In One 5.6 5.6
NEW All-In One 10.0 20.4
Super Power 10.3 10.8
CF=>IDE=>USB 9.8 22.3
You can see that the bottleneck varies between reader and card. Looks
like your 10-12 for an Ultra II is card limited, as expected.
