Qnap SS-839 Pro Turbo NAS


The SS-839 Pro Turbo NAS is the 8-bay, 2.5" SATA HDD network-attached storage server for business users who need a power-saving, high performance, and reliable network storage solution with professional features such as advanced RAID protection, built-in iSCSI target service, and AES 256-bit volume-based encryption.

Energy-saving and quiet design

The SS-839 Pro is the smallest 8-bay NAS in the market and can be easily deployed anywhere in the office. It is also an energy-saving storage solution with excellent cooling and low noise design. The power consumption of the NAS is only 34W in operation (in RAID 5 configuration with eight 500GB hard drives installed), which helps save your electricity expense to a large extent.

Powered by Intel Atom 1.6 GHz CPU and 2GB DDRII memory, the SS-839 Pro supports RAID 0/ 1/ 5/ 6/10/ 5 + hot spare, 10+hot spare, single, and 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-839 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-839 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.
The SS-839 Pro supports file sharing across Linux, UNIX, Mac, and Windows platforms. Versatile business applications are supported, e.g. file server, FTP server with encryption, printer server, web server, and encrypted remote replication. Also, Windows AD (Active Directory) is supported to help create an easy-to-access environment and lower the maintenance cost.
The handy LCD display on the NAS provides a speedy and easy approach for IT administrators to initialize the NAS and set up the RAID configuration without using any computer. The system information and settings are also displayed for easy management. The schedule power on/off feature is available on the NAS for IT administrators to flexibly manage the NAS server's up time according to the working hours. Also, the smart Wake on LAN is supported for convenient remote wakeup of the NAS in the local network.
