It will not fry your drives, if your drives got fried, I want to know.
I want serial numbers and the maker and when/where they were returned.

You are doing Ultra-66 speeds my friend.
The fastest ATA drives out that are not public yet are in 39-42mB/s.
Also SCSI can not sustain rates much better than maybe 60mB/s.

Sure I can get 100mB/s in ATA on an analizer as can SCSI do 160mB/s in
that environment.

Not until media/platter densities get to 25MB/platter with 15K RPM drives
will we see even disk IO approach 100mB/s.

I just wish people could understand that these are max-transfer rates and
that drives do not exist that can run kind of IO in a sustained rate.
