· USB cable · Manual 2 RAID Function What is RAID? RAID (Redundant Array of Independent Disks) is a set of technology standards for teaming disk drives to improve fault tolerance and performance Why RAID? Increased data protection. If in an unfortunate event where a drive fails, the same data is preserved on the mirrored drive. Intelligent array controllers can apply different types of RAID for different hard disk drives. Increased overall network system data capacity. Increased I/O read/write efficiency.
3. Install the hard drives and turn on the power. 4. Format the drives. 5. Done Note: Changing the RAID mode will require you to re-format the drivers. Make sure to backup all existing data first! ※ Normal Mode (Non-Raid): Normal mode is the default setting of HDD enclosure, and will not use any RAID mode. In Normal mode, both of the two hard disks inside the enclosure are in an independent operation state, and also will be identified as two separate drives in the system explorer.
will be lost. ※ RAID0 (Striping): A RAID0 array divides data into two parts respectively in the two hard drives. The theoretical storage speed of the array is twice that of a single drive, and actual capacity equals twice the size of the smallest capacity hard drive(between the two hard drives). The deficit of a RAID0 array is that if any hard drive fails the entire RAID array will not be restored, and the data will be lost.
※ RAID1 (Mirroring): A RAID1 array mirrors data written to the two hard drives equally. The capacity of the array is equal to the smallest capacity drive in the array. Storage speed is same as a single drive. The advantage of RAID1 is that if any hard drive fails the other drive will still carry all data written to the drives. Its deficit is that the maximum capacity of the array is equal to the smallest drive in the array..
3 System Setup 3.1 Hard Drive Assembly The drives can be installed at any position, there is no specific order required.
Step 3: Insert the HDDs to the 7+15P SATA connectors on the PCBA.
Step 6: Fix the back panel by four screws Step 7: HDD Installation completed
3.2 Connect to computer 1.Connect one end (type B) of the USB cable into the B USB Port of your HDD enclosure. 2.Connect the other end of the USB cable (type A) into any active USB port of the computer. 3.Connect the power supply to the enclosure and power up the enclosure 4.Let the OS search and install the driver automatically. 5.Use the disk management tool(PC) or disk utility(MAC) to create a new partition and format the drives 6.Open “My Computer” to see your external hard drive ready to use.
3.3 Files Backup Application Please consult the help of application software for the backup application installation and operation. 3.4 Replacing Hard Drives When one drive fails, the HDD LED will display below state: If HDD1 Fails: LED1 off If HDD2 Fails: LED2 off If one drive fails and the RAID mode is set to RAID0 or JBOD,the data will be lost and the system can not be accessed again until the drive have been replace. 1. Check the HDD LED state and replace the faulty drive.
3. For RAID 0 and JBOD, restart the system and then format the drives again. 4. For Non-RAID (Normal Mode),simply format the new drive. Note: We recommend not turning off the power during the rebuild process but if the process is interrupted,it will continue rebuilding the data as soon as the power is turned back on. FAQs: Q: Can I use external USB hub? A: Yes, USB hub works in the same way as the computer USB ports Q: My computer doesn't have USB 3.0 port, Can I use USB 3.0 host adaptor? A: USB 3.
