True, but it's also not as reliable on SSD's as people think, because they will tend to run out of write endurance nearly simultaneously. Still protects you from actual failures, which is nice, but, far from bulletproof. Not as much of an issue with HDD's, but, you also need many HDD's to achieve the real world performance of even a single SSD and that gets expensive in terms of drive cost and power usage.
