Using hdparm, (I realize it's maybe not the best hard drive benchmarking tool, but it is the one most people have available) and I get the following results doing hdparm -tT /dev/hde /dev/hde: Timing buffer-cache reads: 128 MB in 0.78 seconds =164.10 MB/sec Timing buffered disk reads: 64 MB in 1.73 seconds = 36.99 MB/sec I may be misunderstanding what you are saying, but my performance seems pretty good to me.
