This is an idea I just thought of regarding HDDs that act up with certain RAID controllers. Bear with me while I explain it. I have the ARC-1220 controller and 4 Samsung HD103UJ drives. They aren't playing nicely together.
All other HDDs I have found are more expensive. And the Samsung drives perform well - better than most according to a review I read. So keeping the Samsung drives is attractive.
And I did not find any non-RAID PCI-Express x16 sata controllers with cache at a good price.
So I'm thinking of how to keep these parts and get the best bang for my buck.
Here is the new idea:
I could set the drives as pass-through drives (or maybe JBOD) in the controller BIOS and then use Linux's software RAID.
Initially I rejected this idea because it seems stupid to have a nice RAID card and not use it fully. But now would like to find out more...
Will the I/O requests benefit from the controller's cache memory in a setup like this? How could I expect a setup like this to perform compared to a more typical setup with the ARC-1220?
I would probably have to use RAID-10 instead of RAID-5, so that will cost me some space. Will Linux's software RAID-10 perform better than Areca's RAID-5?
