Thank you, David, We are using RAID 5.
But, could I bring a point here. A RAID device is usually serves to preserve data, by creating a mirror copy of files on its hard-drives, devices. If this is true, then for a large query that requires a large temp file that would exists on its HD for a long time and in my case it takes over an hour to get the answer back. Would it not the RAID try to make a copy of the temp file, by doing so would it not prolong the return of the answer?

It also depends on what kind of RAID you are using, and how well the RAID implementation (typically the RAID controller) works. /David -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
