Alan Johnson, LSI's Customer Manager, outlines a demonstration that pits 6Gb/s SAS drives head-to-head with 12Gb/s drives. One of the greatest benefits of the jump to 12Gb/s SAS is the enhanced throughput enabled by the protocol. However, a doubling of throughput doesn't always equate to a doubling in performance. In this test, the performance enhancement adds up to a whopping 5x improvement.
Testing with a MySQ_ database and the TPC-H benchmark yields a 15 user workload, but the use of 12Gb/s HST SSD800MM (Product evaluation here)creates a large jump up to 80 users. This increase also comes along with a noticeable decrease in latency, while also preserving data protection within a RAID 5 configuration.
