Please Help!!!!!!!!!

I have 2 Hitachi SATA drives in a RAID0 configuration on an 865 PE platform. In an effort to improve performance, I'd like to learn how to do the following:

1. Turn off write verify.


(Some SCSI hard drives/controllers may have write verify on; this feature checks that the data written matches the data on the disk by reading and comparing it. While this function is very important for data integrity, the performance hit is large)

2. Turn on write cache.

(Commonly, the write cache may be off (i.e. write through mode). This is done to protect the data in case of power/system failure by making sure it is always written to disk synchronously. Again, this feature causes a performance hit so enable only if necessary)

Thanks!

Anyone?

I may be wrong, but if your harddrives are SATA why are you worried about a SCSI setting?

Don't know how to turn on write cache. But if you go to device manager and check the properties for the drive. Can see if it's enabled.

Thats because the controller shows up as an Intel 82801ER SATA RAID Controller in Device Manager. The text in italics are from the Tips in Sandra 2004 - but after giving these li'l tips, there's no attempt at an explanation of how to get around to it.

Change your hardware SCSI options in the bios. Change your windows write cache options in your device manager in your drive controller options; there should be a check mark setting. Recommend you enable your cache for performance.
