While I was testing random read/write performance on the X25-M G2, it seems that my controller (ICH9R) might be the thing holding me back. Now that SSDs have destroyed the random IO barrier, we start to run across interesting limits that hard drives can't ever hope to reach. Anyone have information about limits (bandwidth, latency) for these controllers? Single drives, RAID, anything. Trying to do some detective work here.
