Exactly. And additionally, enterprise SSDs are far more reliable than consumer SSDs, in a RAID-1, where both disks will get the same identical write pattern, the risk for a double failure at the same time is high. And if you have to proactively replace an SSD before it fails, then your are not using "inexpesive" disks anymore.
