Both 3ware boards are on similar based hardware: Tyan S5120AGNF (tomcat=20
i915g), PIV 3 ghz-HT disabled, 2GB of RAM. Mylex board is installed on an=
=20
old PIII 800mhz, 768MB of RAM.
I've run bonnie on the 3 servers, theese are the results:
*3Ware 7506 4LP (ATA-RAID 5):
-Per Char- --Block--- -Rewrite-- -Per Char- --Block--- --Seek=

25536.9 98.3
None of theese servers are very busy, and the tests where performed under=

normal load.=20
3Ware 9500s performs very well, but be carefull, acpi enabled hangs the=20
server every day, and disabling it will hang it every 10 :(
If you're interested about ATA/SATA RAID you should try to get some=20
information on promise boards too. Hope someone in the list can help.
