I' sorry I am having one of those brain dead days. So instead of descriding right myself take a look here this should help better than I am. http://www.sql-server-performance.com/statistics_io_time.asp But Logical should be as low as possible and scan count should be kept low but is not as critical as logical reads, so high scan count with a lower logical should perform better.
