What is the current highest disk performance chipset?

[sirus]

Hi there,

I am looking into converting my hard disk storage to Linux RAID and would like to upgrade my motherboard, but I wanted to ask phoronix users what is the current overall best chipset for high disk performance and Linux. I am currently running an AMD AM2 nforce4 motherboard and the performance is moderate.

Here are some PTS results:

http://www.phoronix.net/phoronix-test-suite/remote-graph/graph-remote.php?g=BAR_GRAPH&t=IOzone&s=Write%20Performance&n=3.291&u=MB/s&i=nForce4;&v=58.92;&p=HIB&x=1.0.5

http://www.phoronix.net/phoronix-test-suite/remote-graph/graph-remote.php?g=BAR_GRAPH&t=IOzone&s=Read%20Performance&n=3.291&u=MB/s&i=nForce4;&v=866.67;&p=HIB&x=1.0.5

Here is a quick hadparm -Tt test:
/dev/sda:
Timing cached reads: 2418 MB in 2.00 seconds = 1210.55 MB/sec
Timing buffered disk reads: 228 MB in 3.03 seconds = 75.34 MB/sec

Thanks for any advice.

Sincerely,
sirus

If you can afford it go with a hardware raid solution and a raid 10, look into the Areca or 3ware cards. I have a 3ware 9550sxu 8 port with 8 500GB 7200 drives in a raid 10 (and it is mind numbingly fast). Fakeraid will suffer greatly on IO performance when your system is under heavy load.
