Thank you, i'm not expert about these things. Can u plz tell me if there any other better option than ahci/raid? Also can u plz tell me why not should i use raid? By googling i see that raid have advantage of adding redundancy and data protection to clustered drives, should i ignore this advantage of raid? Forgive me if my questions are stupid.
OK, RAID.

RAID 1 is mirrored. Data mirrored across 2 or more drives, for physical drive redundancy. Not 'data protection'.
But you get 1x the size of the smallest drive, and the performance of the slowest.
With your two drives...500GB SSD and 1TB HDD, yoiu get a 500GB volume that runs at the speed of an HDD. Totally not what you want.

A properly configured RAID 1 might be helpful if you were hosting a webstore, and any actual unscheduled downtime = actual lost sales.
A RAID 1 would let the system limp along until such time (the next day) as you can schedule downtime to replace the failed drive, fail over to some other temp backup, and rebuild the array.

Such a system ALSO needs an actual backup of the data. RAID 1 does nothing for your data.
For instance...if your system were affected by a ransomware virus, that RAID 1 does nothing. Many large companies and govt organizations are finding this out.

Better options?
Your actual data is much better protected with an actual backup routine.
In need, you slot in a new drive, and recover from the backup that ran last night. Little if anything is "lost".

AHCI.
Ignore anything "RAID" related.
