You administer a SQL Server 2008 instance. You plan to deploy a new database that has the following capacity requirements: 275 GB for the database data file; 50 GB for the transaction log file. The storage array has six 100-GB disk drives available for the database. The disks are attached to a redundant array of independent disks (RAID) controller that supports RAID levels 0, 1, 5, and 10. The write performance of the transaction log needs to be maximized. The database and transaction log files must be protected in the event of a drive failure. You need to design the storage system. Which storage configuration should you use?（）A、A single RAID 5 volumeB、A single RAID 10 volumeC、A RAID 0 volume and a RAID 5 volumeD、A RAID 1 volume and a RAID 5 volume
