The SS-439 Pro houses four reliable and low power 2.5″ SATA hard drives with the total storage capacity of up to 2TB. It is particularly designed for business users who are looking for a network storage solution of high data security for data backup and numerous powerful server applications. The SS-439 Pro is an energy-saving server with low heat output and low noise level.

Powered by Intel Atom 1.6 GHz CPU and 1GB DDRII memory, the SS-439 Pro supports RAID 0/ 1/ 5/ 6/ 5 + hot spare, single, JBOD, Online RAID Capacity Expansion, and Online RAID Level Migration. To meet the demand for high security data protection of the business users, the SS-439 Pro supports AES 256-bit volume-based encryption. The encrypted disk volumes of the NAS must be unlocked by the encryption password to be accessed, which eliminates the fear of confidential data leakage if the hard drives or the NAS were stolen. The SS-439 Pro can serve as a NAS and an iSCSI target server. The built-in iSCSI target feature provides an affordable IP-SAN (Storage Area Network) alternative. Also, the “Virtual Space Allocation” (Thin Provisioning) feature is provided which allows you to flexibly allocate the capacity of iSCSI LUN (Logical Unit Number) at the beginning regardless of the physical volume capacity.
