3.3 HDD Installation
3.3.1 Selecting HDD Model
Adopt the certificated professional HDD models to ensure the stable running of the system and
the reliable data storage. It is highly recommended to purchase the enterprise-class hard disks,
e.g., Seagate Constellation™ ES, Western Digital WD RE3 and WD RE4 series hard disk. The use of
non-enterprise-class hard disks for establishing RAID may cause instability of the system, thus
leading to the data damage. In case of hard disk failure, please replace it with the functional one
immediately so as to prevent the data loss or performance degradation.
Please refer to the List of Compatible HDD Models of our company for recommended HDD
models.
In order to avoid damages during transportation, it is recommended to package and transport
the hard disks separately from the chassis of network storage system.
