E isso seria um ataque ou software baseado em hardware?
O design que você "desenhou" acima, realmente não teria nenhuma melhoria significativa com o RAID ... Se alguma coisa tornar sua configuração mais complexa, então ela precisa ser. Estas são apenas unidades de 320 Gb ...
Este artigo, link Vai para o benchmarking de um setup similar, e basicamente o burst read tem um aumento de 50% +, mas a leitura sustentada tem apenas uma diferença marginal ... No geral, para as atividades sustentadas apenas uma diferença de ~ 5% ...
So, does RAID0 really increase disk performance? Yes, definitely. In our tests RAID0 doubled the average transfer rate of our hard disk drive.
How this disk performance increase reflects on overall system performance? It will depend on the kind of application you run: programs that make a lot of disk access will be the ones most benefited, of course. On PCMark05 this increase was between 4.44% and 8.82%, while on SYSmark2004 the best result was on Communication batch, where we saw a 15.25% performance increase. On this same program, Office Productivity performance was increased up to 6.52%, while we saw a performance increase up to 8.52% on 2D Creation batch.
