Thanks everyone for the help so far. Fast forward this to today
I ordered the Areca ARC-1212 RAID card; I got an open box version which was $100 less than retail with full warranty, accessories, from a reputable shop. I will probably put that $100 I saved on the ARC-6120 battery for the write cache. I also ordered the miniSAS backplane from MaxUpgrades, so at the end of the week, I should be good to go and ready to rock.
Now of course there is something I have not yet considered, but it looks like I need to. Unfortunately, I don't have time to fully reinstall and configure my desktop machine. Is it possible for me to simply transfer the "software" RAID 10 I have already set up to the Areca card and set the same 2 drives as the stripes to mirror the other 2 drives?
Basically my current drive configuration is [a][a]==stripe== for RAID 10. When I move it to Areca card it will be in the same configuration, do I need to reinstall everything? The reason I bought the card now, is because when I do find the time I will reconfigure everything into RAID 5, but again at this time I don't have time for a full reconfiguration.
Of course all this worry is fruitless if I can just clone my RAID10 into the RAID5?
Can I just run the Install DVD, run Disk Utility, make an image of my primary RAID to an external drive, redo the entire array into RAID 5 with the Areca card, restore from the cloned image to the new RAID 5, and be good to go?
nanofrog: Where is the list that says what drives I should use?
Regards.
