I have computer with 3 hdds. One is ssd, 2 others are hdd. I want to install Debian 10 to all 3 disks as one big system.
What do you mean by "one big system" ? One big filesystem ? Why ?
What to use, raid or lvm?
If you are concerned with performance, do not mix SSD and HDD in an LVM group or a RAID array (except RAID 1 with --write-mostly as already mentionned).
If you are concerned with disk fault tolerance, use RAID with redundancy (not RAID "linear" or RAID 0).
Note that you can set up LVM on top of RAID.
