Up to now, I always tested my hds with Dr. Hardware for DOS ;-) or with some Windoze software, which also could switch on or switch off the cache due to user request. But the results with caching are not significant anyway in my opinion, because it is important, at what speed the drive can read permanently (at least for my applications, I think, other people might have other opinions...).
