If you are really newbie in Linux - I can advice you to try FreeBSD. By default FreeBSD (as of version 3.2) is much less aggressive in caching and buffering. I never saw Linux greedy caching/buffering working good - it always has some stupid edge cases when it is easier/faster to power-off/power-on/fsck system, rather than to get to console and kill offending process. But sure - Linux's throughput is much higher that in *BSD. Benchmarketing.
