I am not too familiar with RAID and would appreciate some input on my basic questions: To set up RAID, does it need a special RAID controller? Can it be added on or must it be built-in and supported on a motherboard? Say I have a HP laptop, which obviously doesn't come with RAID. If I buy 2 identical SSD and want to do a mirror (RAID 1), how do I go about getting a RAID controller for a laptop? Are there software-based RAID? Is it possible to do a third-party, aftermarket RAID set up on a laptop?
