I bought the WD raptor 10000 RPM 150GB drive but it scores only 75 on Xbench1.3 and the WD disc WD2500AAJS that came standard with the macpro scores 84. Is there a better benchmark or am I missing something?

Try this and let me know too how much difference you see. I distrust Xbench or to qualify my statement, it does not tell me meaningful and resourceful results.

XBench is about as reliable as Fox News. Kinda fun to watch but you know you're not really getting the truth ;x

Don't worry about it.

Though, the WD1000 isn't exactly the fastest drive out there (hasn't been for a long time); the 10K RPM spindle speed doesn't guarantee you'll have (relatively) high transfer rates given its relatively low (compared to today's drives) areal density.

The perpendicular recording technology enabled much higher areal densities and helped to significantly improve speeds; the new terabyte drives are good examples of that.
 
Interesting.

I ran the AJA test on by 160 GB Boot RAID disk that's comprised of an 80 GB slice from my Seagate 1 TB drive, and an 80 GB slice from one of my Seagate 750 GB 7200.11 drives. The file system cache was Disabled.

Write: 201.5 MB/s
Read: 206.0 MB/s

Which is almost exactly what xBench gave for the Sequential Uncached Write (4K blocks), and the Sequential Uncached Read (256 blocks). Those two particular categories are the highest numbers I get using xBench.
 
I completely forgot that I posted this back in November.
Since then I have purchased 2x 1TB samsung drives running software raid 0.
Results using the AJA benchmark:
WD1500ADFD raptor write 78MB/s, read 82MB/s
seagate ST3500630 500GB write 47, read 74
samsung 2x 1TB raid 0 write 207MB/s, read 215 MB/s
