What I’m worried about is that once one drive fails, then I won’t want to replace it because I want to go full SATA. But then that would mean my NAS storage would shrink and loose data.
That means that I have to replace all drives to data at the same time, and if I have lots of data on the hardware said SAS drives. How do I transfer all that data to the new drives ?
Any ideas? The best I can think of is to have 2 pcie cards one with the raid and another data. But how would they share the data if the SATA is not in the hardware raid pool.









Do you recommend SAS over SATA? What would I do of I wanted to move to SATA drives and already having data on the hardware raid? How would I transfer all that?
