Seagate 1TB Barracuda, Rated Good Health but High Read Error Rate & Seek Error Rate..

I recently switched to an old seagate 1tb barracuda HD after one of Western Digital Drives in my RAID 0 setup failed. I've run quite a few HD test's and they all say the drive is running fine (HDSentinel rates the drive at 100% health/performance & it pass seatools tests), but the read error rate seems very high to me. So i'm just wondering should i be concerned or is this normal drive behavior?
