3. Hardware Requirements and Precautions

1. Computers or servers with SATA I & SATA II & SATA III.
2. Hard drive with SATA I & SATA II & SATA III
3. You are strongly advised to set the storage mode (the default is JBOD) before using the
IR2774C-S3.
4. The product allows the user to simultaneously utilize two hard drives manufactured by different
companies. However, if the user expects better efficiency, we strongly recommend the users to
use hard drives manufactured by the same manufacturer.
5. Please make sure that the two hard drives are free from bad blocks or defects prior to installation
in order to avoid system crashes or data loss.
6. The actual storage capacity of IR2774C-S3 recognized by the system may differ from the total
capacity stated on the hard drives combined once the drives have been formatted.
7. It is highly recommended for users to back up important data contained within theIR2774C-S3
unit on a regular basis or whenever the user feels necessary to a remote or a separate storage
device. RAIDON will not be responsible for any lost of data caused during the use of the unit or
the recovery of the data lost.
8. In order to maintain optimal data security, employing hard drives equipped with Shingled Magnetic
Recording (SMR) technology for Redundant Array of Independent Disks (RAID) configurations is
not recommended.
Note :
Once the drive mode configuration has been completed, re-configuration using the same hard
drives to set the drive mode will result in complete data loss. If you must change the drive
mode, make sure to backup all data prior to the mode change.
