My 4T Book thunderbolt duo

My 4T Book thunderbolt duo has 2 bays which comes with 2 hard disk.

It is possible to replace one of the hard drive with a SSD instead? This means

one SSD and one hard disk.

If possible will I still be able to configure to RAID 0/1 or seperate drive?

Hello,

I have never tried this since it is not supported. Lets see what other users can share about this.
