Fusion drive: replace SSD and HDD vice-versa
I did the trick by Trent Fitzpatrick's recommendation. Everything works. Speed doesn't changed. Probably it's because I've just made a Fusion Drive and there need some time, probably it doesn't affect at all. But Write 120mb/s and Read 380 mb/s really slow for Fusion Drive I guess.

I'll wait some time and if speed doesn't will change I guess I'll replace SSD and HDD again because HDD tray has some shock protection.
