I don't know much, and it's probably my own ineptitude, but I've never 
been able to get hdparm to work with scsi drives.  And for ide drives, 
I've only been able to get hdparm to give me read metrics (hdparm -t).

Maybe it would make sense that the only way you can measure the 
sustained write speed of a program would be to write a program that does 
a similar task?  So you might be stuck doing that?
