My first recommendation is to stick with blockio due to the raid5
write hole possibility when using software raid.

what windows version, and if not server2008, did you align the
partitions? (there's a 2003 and a 2008 R2)

dd is going to use the initiator OS's cache, make sure your test file
size is 2x the ram in the initiator, if not the target too.

Also xfs is much better at dealing with large files than ntfs.  Best
apple to apples test is going to be on raw unformated partitions

I'm not familiar with BST5.  I typically use iometer for both OS's.
