The ASUS one doesn't have its own RAID controller nor PCIe switch onboard. It relies on the motherboard-provided PCIe bifurcation and if using hardware RAID, it'd use AMD's built-in RAID solution (but I'll use software RAID via Linux dm/md). The HighPoint SSD7500 seems to have a proprietary RAID controller built in to it and some management/monitoring features too (it's the "somewhat enterprisey" version)
