A company installed a new server to manage its electronic image storage. They have two distinct image sizes： 2KB and 16KB. Two distinct arrays are created on a ServeRAID adapter. The first array will store all of the 2KB images， and the second array will store all the 16KB images. The RAID stripe size was left at the default size of 8KB. After installation， a performance problem is identified. According to performance monitoring， 80% of the images are 16KB. Which of the following will best optimize performance？（）A、Change the stripe size on the RAID controllerB、Change the stripe size to 1024K on the RAID controllerC、Change the stripe size on the RAID controller for the first arrayD、Change the stripe size on the RAID controller for the second array
