RAID 1 Mode (default) 1) Insert two brand new hard drives into MR2020 . 2) As RAID 1 is composed of two hard drives, it can be referred to as disk mirroring, each data will simultaneously be written in two hard drives and the data in two hard drives are exactly the same . Whenever one of the hard drives is failed, the system is still able to work normally. Once the failed hard drive is replaced by a new one, MR2020 will start auto-rebuilding. The computing method of RAID 1 hard disk capacity:【total capacity】= 【minimum capacity of hard drive】 Ex: 2 × 500GB HDD=500GB 1 × 500GB HDD+1× 200GB HDD=200GB 3. RAID 0 Mode 1) Insert two brand new hard drives into MR2020 . 2) The RAID 0 combines two hard drives to work as a large hard drive which provides the efficient read/write performance. The computing method of RAID 0 hard disk capacity: 【total capacity】= 【hard drive number】x【 minimum capacity of hard drive】 Ex: 2 × 500GB HDD=2 × 500GB=1000GB 1 × 500GB HDD+1× 200GB HDD=2×200GB=400 GB Hardware Installation 1. Unlock the hard drive tray lock. 2. Press down the button for hard drive clamp. 3. Pull out the hard drive tray kit. 4. Install a 2 . 5” hard drive on the hard drive tray. 5. Secure screws from the screw kit in 4 positions. 6. Refit the hard drive tray into the MR2020 . All Messages Displayed on the LCD 1. Booting MR2020-2S-S2R v3 RAID-1 v121105 1 2. Normal Operation 3. Drive Failed 4. Rebuild (After inserting new hard drive. it will start auto-rebuilding 10 seconds later if there is no command made.) 7. Install device into one of the CD-ROM bays with screws from the accessory kit. Then properly connect SATA cable and DC cable from your system to the device. 8. Power on your system after hardware installation is completed, and your operating system will automatically detect the hard drives from booting. Then follow the steps from your operating system to partition and format the drives when necessary, device will be ready to use once the format is completed. LED Instruction | Power On | ALARM LED

FAQs

What is the factory default RAID mode for MR2020-2S-S2R v3.0, and can it be changed?

The factory default is RAID 1. Change the RAID mode only by entering the RAID Mode screen and confirming with “Yes”; otherwise press “ESC” to skip.

What is the default password for the RAID mode setting screen?

The default password is 0000.

How do RAID 1 and RAID 0 differ in data behavior and capacity calculation?

RAID 1 mirrors data across two drives, so the system continues operating after one drive fails and auto-rebuilds after replacement. Capacity uses the minimum drive size for RAID 1, while RAID 0 combines drives for a larger capacity using drive number times the minimum drive size.
