Exteremly Slow RAID Rebuild/Verify

I recently installed a HighPoint RocketRAID 2220 RAID controller in our
IBM server. I am very concerned that something is either misconfigured
or not performing as intended. When I rebuilt the array, it took
around 60 hours to complete. I am not very familiar with RAID arrays,
but from what I have read, this is an inordinate amount of time for an
array to rebuild itself. Furthermore, I am now in the process of
running a verify process (after the array has been in use for about 2
weeks) and this is taking about 3 hours to complete. I sent an e-mail
to HighPoint and they suggested I ensure the BIOS is current and the
drivers are current. I downloaded the latest copy of the drivers, but
the O/S (Windows 2000 Server) will not allow me to install them. It
keeps telling me there is already a valid copy of the drivers installed
despite the fact I am trying to install newer drivers. They also told
me to ensure the caching was enabled. I have enabled the read ahead
caching, but not the write caching. We use the server for our database
applications and I have read it is not a good idea to enable write
caching if you are hosting databases on the RAID array. Should I be
concerned about the sluggish performance of this controller, or am I
just worrying too much? Thanks.
