Great forums, I have been reading them for a few days now.

I am planning to set up a raid 6 using the hardware raid controller, HighPoint RocketRAID 3530 PCI-Express x8 SATA II (3.0Gb/s) Controller Card. The card has 256 mb DDR 533 ram and I will use it in a PCI express x8 slot. It is able to control 12 drives. I want to give win 7 its own drive as raid 0 or raid 1. I have not decided on the 0 or 1 yet. Anyway, should I use the raid card to set up the seperate raid for the OS or use the Mobo controller? I know that the raid card is more reliable than mobo raid, but can I expect it to be as fast? My machine is pretty fast now using just Samsung F3's as the C drive in a raid 1 configuration.

Mobo is Gigabyte 890FXA-Ud5 with the following storage interface:

South Bridge: 1. Support for SATA RAID 0, RAID 1, RAID 5, RAID 10 and JBOD
2. 6 x SATA 6Gb/s connectors supporting up to 6 SATA 6Gb/s devices

GIGABYTE SATA2 chip: 1. 2 x SATA 3Gb/s connectors supporting up to 2 SATA 3Gb/s devices
2. Support for SATA RAID 0, RAID 1 and JBOD
3. 1 x IDE connector supporting ATA-133/100/66/33 and up to 2 IDE devices

JMicron JMB362 chip: 1. Support for SATA RAID 0, RAID 1 and JBOD
2. 2 x eSATA 3Gb/s connectors (eSATA/USB Combo) on the back panel sup- porting up to 2 SATA 3Gb/s devices

Also can I load the programs on the Raid 6 ( d: ) and expect at least the same speed that I have now?


MOBO Processor is AMD 1055T
Ram Is G Skill 8gb
4770 512 radeon graphics

Thanks in advance for any help

The onbaord will probably perform equally as well since you would be using RAID 1 or RAID 0, this would not bethe case with a parity RAID such as 5 or 6 where XOR calcs need to be done since the highpoint controller has a dedicated processor. I would use the onbaord controller running RAID 0 and then image this colume to your RAID 6 array. This will give you optimal performance as well as good redundancy. If this was a server I'd say use RAID 1.

Tokencode,
That sounds like a very logical solution. If i load all the programs on the raid 6 with the OS on a seperate drive, do you think that i will see much of a loss in performance?

Thank you
