SATA I/O Performance
Although storage performance and USB 2.0 throughput has decreased a bit when compared to the ICH9, there is some noticeable improvement in I/O performance as you will see on the following pages. This means that ICH10R is capable of performing more storage I/O operations per second than the predecessor ICH9R.
RAID 0 I/O Performance
Intel managed to increase RAID 0 I/O performance by a considerable margin. ICH10R is quicker than other chipset controllers in most of the benchmark runs.
