SSD + HDD - create fusion drive or not?

[Renecek]

Hi,

have question. I have primary SSD, secondary HDD. Both disks are connected to my macbook pro. What is better? Separate disks or create fusion drive? I'm using only OSX, not windows via bootcamp etc.
If I create fusion drive, do I need to use TRIM enabler?

Thank you.

I would suggest making a fusion drive setup. Are both drives internal? Fusion will only work with 2 internal drives.

Yes, both drives are internal.

btw why I see 18 disks in terminal?

There something bad. There must be disk0 (ssd), disk1 (hdd), am I right? So how can I delete other disks please?

and another problem, if I type diskutil cs create Fusion disk0 disk1, it shows me error: could not find disk for fusion
