They were not really benching ssds they were benching the raid controller cache.We know the 1880ix (in raid 0, no parity needed), can deliver 2600-3000 MB/sec from other benchmarks I have seen using SSDs.
Why they even bother posting cache benches in the storage section is beyond me since it just seems to spread misinformation about what certain raid controllers are really capable of with actual drives and not cache.
