Confused on perfmon stats....

Here is the deal.
Buffer Cache Hit Ratio is consistently above 98% BUT my IO seems to be going
nuts too (High).
Doesnt this seem kinda ironic ?
thanks
GAJNot really. You could be writing data out at a high rate. Also, Buffer
cache hit ratio includes hits from prefetch, so if read-ahead is working,
the cache could be loaded before the query actually needs the information.
Cache hit ratio is only one number to look at to determine the health of a
SQL server.
