I have a drive that is failing in my RaidZ2 pool. The general consensus seems to be that WD Red disks should be preferred. However, I have a server supporting SAS. Am I safe to connect a SATA drive to that? The thinking seems to be yes, but I wanted to confirm that this makes the most sense.
My current disk is a 2TB drive. Does replacing it with the same size make the most sense? Or should I replace it with a larger drive to use with a new pool when I upgrade later? For instance, my current pool is 9x2TB, but I may go with something like 6x4TB or 6x6TB in the near future (likely based on the best value at the time).
Lastly, Amazon has 2 flavors of the WD Red drives. It looks like the difference is that one is 5,400 rpm and the other 7,200 rpm. The 7,200 rpm are quite a bit more expensive, and from the hardware guide it sounds like the recommendation is 5,400 due to lower heat and questionable performance enhancements of a 7,200 rpm drive. However, all of my current drives are 7,200 rpm. Would this make a significant difference?
