In case anyone else wants to use ORION on Windows, I finally figured out how to get it to work. Apparently you have to specify an actual Oracle datafile, not just a directory or empty text file. I put "C:\oracle\oradata\orcl\example01.dbf" in my mytest.lun file, and then ORION worked, giving me the following command-line output:  

C:\Program Files\Oracle\Orion>orion -run simple -testname mytest -num_disks 1 ORION: ORacle IO Numbers -- Version 10.2.0.1.0 Test will take approximately 9 minutes
Larger caches may take longer    

And the following results in mytest_summary.txt:  

ORION VERSION 10.2.0.1.0   Commandline:
-run simple -testname mytest -num_disks 1
 

This maps to this test:
Test: mytest
Small IO size: 8 KB
Large IO size: 1024 KB
IO Types: Small Random IOs, Large Random IOs Simulated Array Type: CONCAT
Write: 0%
Cache Size: Not Entered
Duration for each Data Point: 60 seconds

Small Columns:,      0
Large Columns:,      0,      1,      2

Total Data Points: 8  

Name: C:\oracle\oradata\orcl\example01.dbf Size: 157294592 1 FILEs found.  

Maximum Large MBPS=9.01 @ Small=0 and Large=2 Maximum Small IOPS=52 @ Small=2 and Large=0 Minimum Small Latency=20.45 @ Small=1 and Large=0

I've not used it myself, but Oracle has a tool called ORION for testing I/O systems by creating a simulated database workload. It might do what you want. You can get it from OTN: http://www.oracle.com/technology/software/tech/orion/index.html
