NVRAID vs Intel Matrix Storage

[Megalomaniac]

has anyone seen any benchie or know how do the two compare in terms of CPU usage and perfomance?
(raid 5)

I would avoid matrix raid, the performance is not going to be all that spectactular, and it doesn't really compare to raid 5 in my opinion, also it's proprietary format so if something does go wrong and you can't get ahold of an intel card that handles it, you're out of luck anyway.:

Matrix RAID is a feature that first appeared in the Intel ICH6R RAID BIOS. It is not a new RAID level. Matrix RAID utilizes two physical disks. Part of each disk is assigned to a level 0 array, the other part to a level 1 array. Currently, most (all?) of the other cheap RAID BIOS products only allow one disk to participate in a single array. This product targets home users, providing a safe area (the level 1 section) for documents and other items that one wishes to store redundantly, and a faster area for operating system, applications, etc.

Here is a great wiki link on raid techs: http://en.wikipedia.org/wiki/Redundant_array_of_independent_disks
