if you're into that kind of stuff...

I spent the last couple of days doing a pretty thorough write-up of performance testing the Nvidia MCP-5x RAID controller, the Promise TX-2300, and both FreeBSD and Linux software RAID arrays.



The full article has even more pretty pictures, raw data if you want it, methodology, notes, and commentary. (Protip: both FreeBSD and Linux will double drive throughput - or better - if you tweak their read-ahead cache settings... even using a single vanilla drive, much less a RAID array.)
