So I was earlier recommended to use raid 5. However, the write speeds are incredibly slow (30~40 mb/s) although I know that the array is probably rebuilding. I've been reading around that raid 5 is phased out, should I be worried? I literally just bought another toshiba drive today to get a raid 5 array, I don't really want to spend another 110 to get another drive for raid 1 + 0.
Is there a way to see the progress of the array rebuilding? Or should I look into a cheap raid card ~ 50 dollars. Or maybe run raid 0 with two of the drives and use the third along with another 4tb drive as a backup.
I have a z87 asrock extreme 6 board with a 4770k.
