Volume Write-Back Cache for RAID1 Tags: NAS / RAID Cache Hard Drives Storage Last response: December 8, 2009 4:23 AM in Storage Share simonjshaw December 7, 2009 11:38:01 AM Is it recommended to enable volume cacheing for a RAID 1 volume with hard disk caches already enabled? This is in the context of Intel ICH 8/9/10 Sata RAID and SBS2008 with UPS backup.

The point of it is speed at the cost of some data integrity. Your battery backup should help avoid that. With raid 1 there is some benefit, but the raid 0 and 5 see the most gains. http://blogs.techrepublic.com.com/window-on-windows/?p=... Take a look. Can't find your answer ? Ask !
