Good to have it confirmed.
It is so true that different hardware yields different performance, but a composition of modern components will generally give equally good or very close results. Different chipsets have different qualities and thus varies slightly in performance.
Then there is differences in driver versions can also make a measurable difference, along with modified CPU clock speed (overclocking), or bus clock speed.
In general it is Intel SATA 6Gb/s that provides the better performance for SSDs.
