I've just made a Fusion Drive on my MBP 2012 and restored data from the Time Machine. Unfortunately, right now I read information that the best place for SSD is the main bay of HDD not the optical bay. So I want to replace SSD to the main bay and HDD to the optical bay.
My question is: it's possible without reinstalling the system?
I'm asking because I not fully understand how Fusion Drive works. When I make coreStorage and I put the names of disks (For instance,
/dev/disk1) how it determines where is the SSD and where is the HDD? By manufacture information? So it means that I can replace SSD and HDD vice-versa and it's gonna be fine or coreStorage stores information about each drive how it was determine: first - SSD -
/dev/disk0, second - HDD -
