Performance of dual SCSI HD system

By inwookcho ·
I was told that adding a slower SCSI drive on a chain with a fast SCSI Drive will effectively slow down the performance of the fast SCSI Drive.

Is this true?

thanks

Performance of dual SCSI HD system

No, the slower drive will only go as fast as it is capable, but a faster drive will go as fast as the SCSI controller will let it.

Take a look at http://scsifaq.org:9080/scsi_faq/ for more info.

Hope this helps.

If you are using an LVD (ultra2, U160, U320) and connect a slower drive ( ultra ) on the LVD bus it WILL pull the bus down to the slower speed. This does not occur on slower busses (ultra wide, narrow). See adaptec.com for full explaination.
