Hi,
two SAS HDD ,with RAID1,and another SATA HDD with no RAID
This Might be a issue for the Performance as per the RAID Level or u need to Check by updating the HDD Firmware Offline of both the SAS HDD
| RAID Level | Performance1 |
| RAID 0 | Fastest read Fastest write |
| RAID 1 | Better read Slightly degraded write |
