Hello everyone, thank you for reading. I bought 11 new 5TB drives and they have passed initial SMART testing. Now I am running solnet-array-test-v2 on them for a couple days. There isn't any pool created and these drives are not otherwise in use, the drives are identical. Two of the drives are noticeably slower than the other nine. Eight drives da0-da7 are on a M1015 in IT mode and all are testing at or above average speeds, and three are on the motherboard of a Dell 1900 PE server (16GB ECC, Dual XEON) which the two slow ones are connected ada0-ada2 (the two abnormal drives are ada0 and ada1), I would think that this is itself the issue, but the third drive connected to the motherboard is in line or above with the others connected to the LSI M1015. See results, test still running..
Has anyone experienced this before? Is this normal or expected? I have one drive already going back on an RMA, and want to expedite that process.
