SQL 2012 Standard - Install Path Location Help

Hello, I have a Dell PowerEdge R420 with Windows 2012 Standard and was looking to find out what the best install paths I should use for my SQL 2012 Standard 64bit. The SQL database is for a program call JobBOSS and there are only 5 to 10 users using that will be using the database. I’m going to select all of the features in the SQL setup wizard. I have a Raid 1 which is my C drive (SAS 15k 300GB) that has my OS and programs on it, I have a Raid 5 D drive (SAS 15K 600GB) that has all of my shared data. When I’m in the setup I see that there is a “Shared feature directory” path, should I leave that C: or change it to the D: drive? The next section that I can change the paths is in the “Database Engine Configuration” which I have choses for:

1. Data root directory
2. User database directory
3. User database log directory
4. Temp DB directory
5. Temp DB log directory
6. Backup directory

My question for this section is how I should choose which locations should be the C or D drive to get the best possible performance for my type of server configuration.

Thanks Ryan.
