Upgrading My Storage

Hey guys I just recently purchased the "Firecuda" hybrid drive for my ps4.

I am curious if there is certain steps that are needed to install the PS4 OS onto the SSD portion of the hybrid drive or if the drive will automatically use the OS on the SSD portion of the drive.

I am a little confused on exactly how the hard drive will work but I am assuming the drive will just allocate the most frequently used programs or games ect onto the faster portion of the drive.

Thanks for the help!
