The actual unit is in Brand New Condition.
It's been in my AC closet sealed since October 2022.
I purchased two of these units and am selling this one with upgraded components which are used.
The upgrades will be preinstalled for you and tested by powering up the unit using the 480GB SSD with DSM already installed.
I will confirm that the cache is present and will test each of the four (4) 1Gbit ports and the 10Gbit port to my network. I will than factory restore the unit, seal and deliver.
Used Upgraded Components:
- Synology E10M20-T1 M.2 Adapter 10 Gigabit Ethernet Card
- 2x SNV3400-400G 400GB NVMe Cache
- Synology 2.5" SATA SSD SAT5210 480GB (SAT5210-480G).
"The RS2421(RP)+ and RS2821RP+ units are high-performance storage solutions aimed at SMB customers," said Julien Chen, Product Manager at Synology Inc.
"Abundant storage capacity, upgraded performance, and redundant power make these units perfect as dependable file servers," Chen said. "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."
More than twice as fast
The new RackStation units boast significant performance improvements over their predecessors.1 The RS2421(RP)+ 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.2
Customize for your business requirements
The RS2421(RP)+ and RS2821P+ can be fitted with a dual-port Synology 10GbE or 25GbE NIC3 to improve network throughput, or with a Synology M.2 adapter card and fast NVMe SSDs to create an SSD cache,4 a cost-effective 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.5 By attaching an RX1217(RP) expansion unit, drive bays can be expanded to 24 bays for the RS2421(RP)+ and 28 for the RS2821RP+.

Synology Drive, Chat, and Office enable fluid 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.7 Certified integration with VMware, Windows, and other virtualization platforms ensures painless management of VM storage.
- Comparisons conducted against prior-generation RS2418(RP)+ and RS2818RP+ units.
- Performance figures are achieved in Synology labs with optimized network and configuration settings. Actual performance may vary in different environments. For full details on the test setup, please visit the Synology performance page.
- Compatible NICs include the E25G21-F2, E10G21-F2, E10G18-T2, E10G18-T1. For the latest compatible devices, check the compatibility list.
- NVMe SSD cache can be enabled via the Synology M2D20 or E10M20-T1 SSD cache adapter cards with SNV3400/3500 NVMe SSDs installed.
- Maximum memory upgrades allow for a greater number of simultaneous connections, more hosted virtual machines with Virtual Machine Manager, larger volume sizes, and other enhancements. Please check the datasheet of the device for more details.
- Supports LFF (3.5") or SFF (2.5") SATA drives. Drive compatibility is dependent on Synology's compatibility list. The capacity of all three units can be expanded using a single Synology RX1217(RP) expansion unit, purchased separately.
- Surveillance Station includes two free camera licenses. Connecting more cameras or devices requires additional licenses.
