Why bother with a raid controller? Doing the processing required of RAID takes essentially no processing power. You also don't need to worry about the hardware failing and leaving your disks potentially useless. I do what you do by using a LVM volume group among a couple of SSDs. Logical volumes can be any size up to the size of the entire collection. There is additional functionality in LVM that you may be interested in. I have interacted with one (the process of turning it off). The menu is usable but not as good as a simple CLI interface. It seems to mimic the most basic functionality of LVM - you create groupings of physical disks and then split them into logical disks. I would highly recommend reading about LVM to know what else is possible that these controllers likely do not or can not implement. R0b0t1.
