Question : Problem: Difference nVIDIA RAID and Silicon Image SATARAID5

Hi,
I just put together a computer and I would like to install OS. Before instaling OS i am trying to configure RAID(first time configuring RAID). I have MSI K8N Neo4 motherbord with 8 Serial ATA/ contectors. My question is what is the difference between the two RAID - nVIDIA  and Silicon image RAID. Which is better? .. and if i am correct some of the serial  ATA/conectors are designed for nVIDIA RAID and others for Silicon image RAID, why?
Thank's

Answer : Problem: Difference nVIDIA RAID and Silicon Image SATARAID5

NV RAID (Software)
• Supports up to 4 SATA and 4 ATA133 Hard drives
- RAID 0 or 1, 0+1, JBOD is supported
- RAID function available for ATA133+SATA H/D drives
if you want to make raid with ata drives use the nvidia raid controller,you can make
raid 0 -stripped,quick but not secure
raid 1 -mirroring,secure but much more slowlier
raid 0+1 - combination of the both previos two,
JBOD-just a bunch of disks
read this:http://www.bytepile.com/raid_class.php
http://www.pcguide.com/ref/hdd/perf/raid/levels/jbod.htm
also the nvraid supports sata II ,so up to 300MB/s data transfer


Silicon Image's SATARAID5™ (Software)
• RAID 0 or 1, RAID5, RAID10, and JBOD groups are supported
• Support up to 4 SATA devices connected to a single controller
it's only for s-ata drives but from what i know silicon image makes the best controllers for s-ata and s-ata raid solutions
and supports only s-ata I up to 150MB/s,theoretically much slowlier ,but i'm not quite sure what kind of performance and stability this controller is  able to show,perhaps it's better than the nvidia one,cuz s-ata II is still no standart,all th especs are theoretical values,which doesn't mean that this expresses the reality
both of th e controllers can do raid0 ,raid 1,raid 1+0 so if you want to go for s-ata it's upto you which controller you will choose
