Changes that 15MB/Sec to 25 MB/Sec

For the last 6 months our database disk transfer rate has been at 15MB/Sec
during normal business hours.
Last we the disk transfer rate changed from 15MB/Sec to 25MB/Sec in one day
and has stayed at that rate since. The number of transactions/sec is the
same from the change 15MB/Sec to 25MB/Sec.
What could make this rate change so quickly?
Changes in index planes, larger transactions, and etc.?
Please help me with this issue.
Thanks,Hi
I would not expect this to happen on it's own. Have you checked the event
log?
I would expect the something like defragging, changing the disc layout,
moving the pagefile (or some other application that caused excess head
movement) may cause this sort of thing.
