These results don’t come unexpected. The hard drive RAID array is faster when it comes to high throughput just because there are up to eight drives. However, the two SSDs manage to sustain their 530+ MB/s throughput level constantly, while the drives drop to 430 MB/s.
Peak write transfer rates look amazingly high due to the controller’s caching abilities. Look at average and minimum results for realistic numbers.
Interface performance reflects the storage subsystem’s ability to maximize the impact of the integrated RAID cache memory. Effectively, this number is good for analysis but expect to see it in real life.
