Your OS system is always detecting your operation, and always moving your datas between the two hard drives. They are not moving quite silently and slowly and you can not even notice the process. I read an article about the fusion drive, it said that the datas are cut into very small pieces when being moved. So once anything goes wrong, it’s almost impossible to repair.


I'm not sure I understand your last statement. When files are written they are always ``cut into small pieces'' and distributed on the HDD/SSD/etc. OS X has cached files that are frequently read in areas that are quicker to read for many versions now and it has been quite reliable.

Good Luck,
