No doubt you know that Vista's I/O
performance is not (yet) up Windows XP levels. Microsoft released a patch
last month to fix the problem. Tech Hounds took a look whether or not the patch
helped or not.
Originally, we set out to compare various RAID and AHCI SATA controllers and
what kind of performance we can expect with Vista. But problems during
testing lead us elsewhere - this article. These preliminary testing clearly
shows that kind of comparison is just not possible right now - something is
still definitely broken with Vista's I/O performance.
