Key Features Quad Core CPU Delivers 389.03 MB/s Reading, 361.33 MB/s Writing Four Gigabit LAN Ports with Failover & Link Aggregation Support Scale up to 8 Drives with Synology RX415 Expandable RAM Module (Up to 6GB) High Availability & SSD Read/ Write Cache Support High-performance NAS server optimized for intensive tasks & encryption Featuring a quad-core processor & AES-NI hardware encryption engine, RS815+ & RS815RP+ (equipped with redundant power supplies) deliver the superior performance which is essential for business’s data transmission needs. The ability to expand to 6GB DDR3 RAM & scale storage up to 8 drives with Synology Expansion Unit RX415 give your business the agility to meet evolving workload demands. Quad-core CPU brings high performance Powered by a quad-core CPU running at 2.4 GHz, RS815+/RS815RP+ delivers average 389.03 MB/s reading & 361.33 MB/s writing.1 With this superior performance & a RAM module expandable to 6GB (2GB by default), RS815+/RS815RP+ is a powerful 1U NAS server for mission-critical tasks of SMBs. Ideal encrypted data transmission with AES-NI RS815+/RS815RP+ features a hardware encryption engine, which offloads encryption calculation tasks away from the main CPU. That means files & folders are encrypted on the fly without compromising the performance &9472;delivering encrypted data transmission speeds over 388.66 MB/s reading & 158.9 MB/s writing. Robust scalability up to 8 drives When your data storage is nearing its limits, RS815+/RS815RP+ can be connected to a dedicated RX415 expansion unit 2, letting you easily scale up to 8 drives for additional storage on the fly. With a RX415 connected through an e SATA cable with specially-designed locking connectors, raw capacity can be as high as 48TB.3 Quad LAN ports for failover & Link Aggregation support To ensure your business continuity, RS815+/RS815RP+ features four built-in Gigabit LAN ports supporting failover, which is engineered to provide reliable redundancy even if LAN connection malfunction occurs on one port, reducing the chance of service disruption & costly downtime. In addition, Link Aggregation powered by four LAN ports increases connection speeds beyond the limits of a single network cable or port.
