Synology introduces RS2421+, RS2421RP+, RS2821RP+

Synology has launched its new 12-bay RackStation RS2421+ and RS2421RP+, and 16-bay RS2821RP+, built to excel in large-scale infrastructure backup, business-level file serving, and private cloud services, according to Product Manager Julie Chen.
“The RS2421(RP)+ and RS2821RP+ units are high-performance storage solutions aimed at SMB customers,” she said. ”Abundant storage capacity, upgraded performance, and redundant power make these units perfect as dependable file servers. They also support essential remote work applications, such as Synology Office, Synology Drive, and Synology Chat — our file sharing and productivity solutions that keep workers connected and company data accessible.”

The new RackStation units boast performance improvements over their predecessors. The RS2421(RP)+ purportedly delivers 103% higher random write IOPS and 161% higher read IOPS, while the RS2821(RP)+ delivers 115% higher random write IOPS and 162% higher read IOPS.


The RS2421(RP)+ and RS2821P+ can be fitted with a dual-port Synology 10GbE or 25GbE NIC to improve network throughput, or with a Synology M.2 adapter card and fast NVMe SSDs to create an SSD cache, a method to boost random read/write IOPS of hard drive arrays without occupying standard drive bays.


The rackmount units support up to 32 GB of DDR4 ECC memory. By attaching an RX1217(RP) expansion unit, drive bays can be expanded to 24 bays for the RS2421(RP)+ and 28 for the RS2821RP+.

The DiskStation Manager (DSM) operating system runs on all Synology NAS devices, connecting them to an ecosystem of solutions. Hyper Backup lets users back up NAS data to the cloud and other destinations, while the Active Backup Suite provides a backup of Windows clients, servers, file servers, and virtual machines. Synology Drive, Chat, and Office enable collaboration between
remote workers by providing browser-accessible office applications, file sharing, and chat functionality.

Surveillance Station transforms RackStations and other models into all-in-one surveillance solutions supporting up to 40 cameras. Certified integration with VMware, Windows, and other virtualization platforms facilitate the management of VM storage.
The RS2421+, RS2421RP+, and RS2821RP+ are available from Synology resellers at manufacturer’s suggested retail prices of US$1,799.99, $2,399.99, and $3,299.99, respectively. They’re covered by Synology’s three-year limited warranty.
