RS2418+ / RS2418RP+ Image

The Synology RS2418+/RS2418RP+ is a high capacity, scalable 12 bay NAS designed for small and medium sized businesses

It can support up to 24 bays when connected to a Synology expansion unit and is ideal for use as a file server or a centralised backup destination that can also be seamlessly integrated into virtual environments. Equipped with a PCIe expansion port the unit also supports a dual M.2 SSD adapter for SSD caching or a 10GbE network card for bandwidth–intensive environments. The RS2418RP+ model comes with a redundant power supply to ensure business continuity. The RS2418+/RS2418RP+ is equipped with a quad core processor and 4GB DDR4 memory (expandable to 64GB). With link aggregation enabled the RS2418+/RS2418RP+ delivers outstanding sequential throughput performance at over 1,400 MB/s read and 580 MB/s write.
