Re: poor disk performance with vista and dell xps gen 4 raid 0
Just to clarify a point, when you say drivers for the nVidia - are you
referring to the Video card or the Chipset and the Video card. They
are a different set of drivers.
Normally, a RAID controller has a setup similar to BIOS setup. A
certain keypress at boot when the controller POSTs (Power on
Self-Test) takes you into the setup routine. From here you should
be able to see devices connected and parameters about them.
SATA Mode II (300 Mbps) should run at a UDMA mode of 5 or
greater. Using DiskSpeed32 the array should test at around 80 Meg
per second. (Average). Especially if the drives use perpendicular data
orientation.
Sorry I can't provide more exacting help, but there are just too many
variables at play that can affect/impact disk performance.
