When using Linux software RAID, I was thinking that, from a
performance perspective, the southbridge/SATA controller is probably
one of the most important components (assuming a reasonable CPU).
Is this a correct generalization?
If it is, has anyone done a study or benchmarked SATA controller
performance? Particularly with consumer-grade hardware?
I haven't been able to find much info about this on the web; the
Tech Report seems to consistently benchmark SATA performance:
AMD SB600: http://techreport.com/articles.x/13832/5
AMD SB700: http://techreport.com/articles.x/14261/10
AMD SB750: http://techreport.com/articles.x/13628/9
Intel ICH10: http://techreport.com/articles.x/15653/9
nVidia GeForce 8300: http://techreport.com/articles.x/14993/9
My (over) generalization of the above is that SB600 is to be
avoided, and performance ranking is Intel/nVidia over AMD.
But this is just one set of benchmarks and obviously they used
Windows and therefore Windows drivers, so my simplification really
isn't fair.
Thoughts?
