Intel10R southbridge chips come with Intel hybrid raid...

call matrix mode. it's able to do stripping and clonning with just 2 hard drive.


I have been looking for a review, But i haven't had a luck.


Any one using this? Pros cons?

"RAID 0+1" means something different from Intel's Matrix RAID -- it takes a minimum of 4 drives.

http://en.wikipedia.org/wiki/RAID

Intel's RAID can do some flavor of "0+1", but it's not the same as "Matrix RAID".

Matrix RAID is like partitioning your HD into two parts, and then making different RAID arrays of the two parts across all the drives. It has similar issues to partitioning -- basically that any access across a partition involves a seek, and access patterns which hit both parts come with a heavy performance penalty.

So if you're thinking of getting "really fast" drives and still being able to access "pretty secure" data at the same time, it's not going to work out -- when you're accessing the "secure" data, access time on the "fast" part takes a big hit. However, if your access pattern puts the bulk of access on the "fast" part and the "secure" part only rarely, or if the accesses across are well-separated by time, then it can work out. Things might work better if you keep a separate drive dedicated to the OS. That's at least easier to set up and maintain.

I'm using it with 4 of the WD6400AAKS drives. It's almost as fast as a pair of the drives in RAID 0 and will rebuild the array in short order when required. I had a disk go down, stuck a new one in and in a matter of a few hours I was back to normal.

Would I do it again? I dunno, seems like overkill for a home system that I run nightly back-ups on anyhow.
