Windows 10 supports RAID. This OS is compatible with hardware RAID and can also create software RAID. To create a software RAID, you just need to: Press "Windows + R" keys and type "diskmgmt.msc" in run box to open Disk Management. Right click the whole disk to convert it from basic disk to dynamic disk. Right click unallocated space and choose "New x Volume"("X" can be "Striped", "Mirrored", or "RAID-5"). Follow the wizard to select disks, and set volume size, drive letter, file system, and cluster size.
