RAID-1 System

The hard drive inserted into the upper drive bay can be operated independently, as a single drive. By changing the setting of the switch on the front, users can choose between this option and automatic mirroring (the default mode), which requires a second drive in the lower bay.
For our test, we used two Western Digital drives, model WD800JB. Mirroring begins right after activating default mode, or after inserting the second drive. In our case, the setup process took about 75 minutes. During that time, we could still use the system, but performance was slightly reduced. If there's a load on the system during the rebuild process, the rebuild is noticeably slowed. Unfortunately, the priority level of the rebuild process cannot be adjusted.
Duplicating Hard Drives
Users who have to regularly create a complete copy of a hard disk drive will really like the ARAID 2000, as the mirroring process described above is perfectly suited for this purpose.
