Phoronix: AHCI vs. IDE Linux Performance Benchmarks

Hitting OpenBenchmarking.org this weekend are some interesting benchmarks comparing performance of AHCI vs. IDE modes under Linux from an AMD Fusion system...

For an evolution of a standard it sure looks dissapointing from those benchmarks

It is too bad that libata maintainer Andre Hedrick recently committed suicide.

Ouch...who's stepping forward to take his place, as this is an important library?

I suppose this is a typical 5400 rpm HDD so it's kind of expected that it doesn't make much difference. Try the same thing with a fast SSD and see if the results are the same.

I agree with that

You've got it backwards. For slower drives, NCQ should help a lot, as heads won't have to seel as much. However, in my experience the difference is no noticeable.
For SSDs, NCQ means nothing.
Other AHCI improvements are not about speed (afaik).

I don't know. Perhaps Jeff Garzik?
