Deployment Recommendations for Application Request Routing

For optimal performance, it is recommended that the cache drive location be a physically separate drive than the system drive. It is also recommended that the cache drive location be a high RPM drive (15K RPM) for better performance. If you have only one physical drive, it is still recommended to separate the system drive from the cache location drive. You can partition the same physical drive into multiple volumes using Disk Management under Server Manager.
