400x UDMA7 CF card faster than 600x UDMA6 ?

I just received a Sandisk Extreme Pro, 32 Gb, 90mb/s (600x) UDMA6 [ http://www.sandisk.com/products/memory-cards/compactflash/extremepro/?capacity=32GB ] and tested it on my D300 and to my dissapointment is profoundly slower than the 32 Gb Transcend 400x (60mb/s) UDMA7 i am currently using [ http://www.transcend-info.com/products/Catlist.asp?modno=264 ]

Speed refers to buffer / moving the contents to card performance
Is that normal?
