It might be really simple but figured I';d ask, if in fact further clarification can be given. typhoon% iostat 1 tty da0 da1 acd0 tin tout KB/t tps MB/s KB/t tps MB/s KB/t tps MB/s us ni sy in 0 21 0.00 0 0.00 0.00 0 0.00 0.00 0 0.00 1 0 1 0 do drive specifications generally contain KB/t information or statistics? I currently have an IDE drive that has the capacity to do 128KB/t and a SCSI drive 64KB/t. Are these stats in fact showing me that there is a limitation with the SCSI drive? Are my file transfering capaibilities less with the SCSI drive? I suppose what do I need to look for in the spcifications when choosing new drives so this does not happen again? - Noah To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
