Tech-Hounds.com has posted part 2 of their "The Quest for Lagfree Gaming" article series

In part 1, we concluded that if you want to play new games at the highest detai, you better be prepared to buy both a high end graphics card and at least 2 GB of memory (assuming you already have a fast enough processor). Having 2 GB of memory not only eliminates most memory related stuttering, but also offers faster load times as well. But it won't solve all stuttering. In part 2, we take a more focused look on storage related stuttering - mostly the ones due to level loads and game saves. It's obvious the hard drive is the bottleneck, so we threw in two 80 GB Maxtor Diamond Max Plus SATA hard drive and configure them as one 160 GB RAID array. The results we got were pretty interesting, RAID 0 do offer some tangible benefits (performance, load times and save times) but it looks like our RAID array is not fast enough to provide stutter free gaming.
