You can 1) pay for software that can resize the partitions on the fly, or 2) backup your data partition, delete it, extend the C: partition into the Unpartitioned Space, then create a smaller data partition with the remaining space, then restore your data.
Try to use aomei partition assistant lite version, it's the free server partition manager. It has the resize partition to allocate your space, check the detailed guide with video. But you will manage the partition with operating system, you'd better to make a system backup image before resizing partition.

as a backup....
Depending on the raid 1 size, get a SATA drive, hang off the onboard SATA interface, clone to it as a working backup.
