Hello, I have two wd 3GB hdd and 2 120GB OCZ drives. I want to setup the hard drives as a raid 1 and have the OCZ drives as their cache. Can I do this with HyperDuo Plus technology? If so, please advise me how to do this?
It is possible, but not advisable, and here's why.
You can create two HyperDuo virtual hybrid drives on a single Marvell 88SE9230 chipset like the SI-PEX40057. Each path running at a max 500MBps.
Next, you would need to create a mirrored volume for your RAID1; but, this can't be done by the controller, since the controller is managing your HyberDuo configuration, thus would only be doable through the OS in a software-RAID.
This is probably not the best idea.
