Hello, and a good day to you all.  I am about to order a new server for my 
job, and I was wondering about the raid controller option. 

The box is going to used for running a very busy database. 

I have the option for
Intel SAS RAID Controller   or 		
Intel SAS RAID Controller w/ Portable Cache Module  (Add $450.00) 

I am planning on running 2 drives as raid 1 for the OS (Slackware), and 3 
drives as raid 5 for the database. 

What is the benefit of the Portable cache module.  I am not concerned about 
the price, just if this is something I should consider. 

Any thought would be great. 

Thank You!!!
