I believe Windows and pretty much everything else sees the RAID 1 setup as a logical volume... so it doesn't really know any better that it's one hard drive or two. Anyway, once you have the SSD, you'll need to do the following:
- Install the SSD in the computer and boot. Make sure it's recognized and such
- Go to Control Panel -> Administrative Tools -> Computer Management -> Storage -> Local
- On the SSD, create a 200MB NTFS partition with the label S:\
- Right click on the S:\ partition and mark the SSD as "Active"
- Clone the Windows partition into the SSD. Use a tool like Arconis Disk Image or EASUS Partition Wizard. Some programs may be okay with the partition capable of storing more than the SSD, as long as the used disk space is smaller than what's left on the SSD. Otherwise you'll have to shrink it (you can use the same tool to do so)
- Open a command prompt as an administrator
- Execute the following command:
Bcdboot D:\Windows /s S:
This is assuming D:\Windows is the Windows partition on the SSD.
- Boot from the SSD.
