   Interesting my DTC controller seems to be slow also. I started using
   a benchmark program Coretest. It on a Vertex V150 it reports 280K/Bytes/sec,
   23ms random track access, and 6ms track to track access, under MSDOS.
   I just ran the same benchmark on a friends PC with and OMTI RLL controller
   with a CDC and it reports 720K/Bytes/sec 23ms and 4ms. Opps forgot to mention   my DTC is also RLL. The OMTI could format 1 to 1. That's about 5x increase
   in data throughput at approximately the same price. Does anyone have any
   benchmark tests to measure disk IO on SCO Xenix? Also has anyone used 
   RLL with SCO Xenix? If so what controllers and/or drives. Any help would
   be appreciated.
