Notes:
- Performance testing was conducted by Synology with 10GbE NICs installed. Actual results may vary depending on system configuration, testing methods, and other environmental variables. Check the performance page for specific details on the testing environment.
- Network adapter cards, expansion units, other PCIe add-in cards, and storage drives are sold separately. Refer to the compatibility list for compatible devices.
- Redundant power only available in the RS2421RP+ model.
- SSD cache can be enabled by using compatible 2.5″ SSDs in drive bays or without occupying drive bays by installing Synology SNV3500 M.2 22110 NVMe SSDs using M2D20 or E10M20-T1 adapter cards, sold separately. The RS2421(RP)+ does not support SNV3400 NVMe SSDs.
- Pictured is a single SNV3500 installed in an E10M20-T1.
- Users have reported total data size reductions of more than 50% when backing up multiple systems with deduplication technology enabled.
