Doing socan cause a hard drive failure.NOTE: Do not mix enterprise class hard drives with entry class hard drives.Your system supports four 3.5-inch entry hard drives and enterprise class hard drives. Entry hard drivesare designed for 8x5 operating environment and enterprise class hard drives are designed for 24x7operating environment. Two hard drives are located in the removable hard drive cage and two hard drivesare located in the fixed hard drive bay.Choosing the right hard drive type depends on the usage pattern. Improper use of entry hard drives(workload rating exceeding 55 TB/year) leads to significant risk and increases the failure rate of the drives.Due to industry advances, in some cases, the larger capacity drives have been changed to a larger sectorsize. The larger sector size can have impacts on operating systems and applications.
