SplitdriveCWin... is a term used to describe a Windows-oriented disk layout in which the operating system’s boot and system files are kept on a separate drive or partition from user data and applications. In this arrangement, Windows may be installed on the C: drive while data, programs, or backups reside on a second partition (such as D: or E:) or on a different physical drive. The approach can also involve redirecting system folders or user profiles to another volume to maintain data separation from the OS.

Common configurations include installing Windows on a solid-state drive or a dedicated C: partition and storing documents, media, and other data on a larger HDD or on an additional drive. Users can achieve this by shrinking the C: volume during or after installation to create new partitions, moving user folders (Documents, Pictures, Desktop, etc.) to another volume, or employing symbolic links to point specific folders to locations on a separate drive. Some setups also use multiple physical drives to physically isolate the OS from data.

Benefits of this layout include easier system reinstalls and imaging, since the OS can be targeted without touching personal data; reduced risk of data loss if the OS becomes corrupted; and potential performance gains when the OS runs from a faster drive while data resides on a slower one. Drawbacks can include increased setup complexity, the need for careful partition and boot management, possible boot issues if the boot or system partitions are misconfigured, and the overhead of maintaining backups across multiple volumes.
