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!!!
