The RackStation RS815RP+ 4-Bay NAS Server from Synology is a reliable, high performance network attached storage solution for SMB environments seeking strong performance that is essential for their data transmission needs. This unit has four drive bays, each of which natively supports 3.5" and 2.5" SATA III 6 Gb/s and SATA II 3 Gb/s hard drives and SSDs. Should users need to expand the overall capacity of their RS815RP+, the optional RX415 expansion unit offers an additional four drive bays that are identical to those offered by the RS815RP+. Additionally, should power to the NAS be interrupted, the RS815RP+ comes equipped with a 250W redundant power supply.
The Rackstation RS815RP+ is powered by a 2.4 GHz Intel Atom C2538 Quad-Core processor, which will allow you to run multiple functions simultaneously. The built-in 2GB of DDR3 RAM will allow quick access to frequently-used files and programs  and may also be upgraded to a total of 6GB by installing a 4GB module into the available memory slot. Network connectivity is achieved via the 4 x Gigabit Ethernet ports with failover support, which helps to provide redundancy in the case that a LAN connection malfunction occurs on one port. In addition, link aggregation, powered by four LAN ports, helps to increase connection speeds beyond the limits of a single network port or cable.
The RackStation RS815RP+ runs on the DiskStation Manager (DSM) operating system, which offers helps simplify managing your RS815RP+, as well as accessing and sharing data. Synology's Package Center also lets users download and install add-on packages that are designed for individual or business needs. A variety of RAID modes are supported, which help provide users with data redundancy, speed, or a combination of both. Supported RAID modes include RAID 0, 1, 5, 6, 10, Basic, Synology Hybrid RAID, and JBOD.
The RackStation RS815RP+ operates on 100-240 VAC at 50/60 Hz and includes an accessory pack and two AC power cords.
