Bob and Larry,

In reviewing the minutes from the SCSI Working Group Meeting on March 10,
we noticed the proposal for making TTD obsolete.  We have found TTD 
to be very useful for providing high performance in our RAID controllers.  
TTD provides some significant advantages, as described in the attached note 
|from Will Renner, a software engineer at Digi-Data.  Other alternatives 
do not provide the same capabilities.

Therefore, I would like to request that TTD not be made obsolete, but rather
that TTD remain an integral part of the SCSI standard.

Thank you for your consideration.
