RackStation RS1221+/RS1221RP+
Performance and Processing
Powered by an AMD Ryzen V1500B quad-core processor (2.2 GHz), the RS1221+/RS1221RP+ delivers up to 2,315 MB/s sequential read and 1,147 MB/s sequential write, with over 100,000 4K random read IOPS. It includes 4GB DDR4 ECC RAM (expandable to 32GB). Users praise its 3.6x better compute performance than the RS1219+ but note fan noise (~40 dB under load). Ideal for file servers, backups, and virtualization.
Storage and Scalability
Features 8x 3.5"/2.5" SATA drive bays (drives sold separately), supporting RAID 0, 1, 5, 6, 10, JBOD, and Synology Hybrid RAID. Expandable to 12 bays with an RX418 unit. Supports NVMe/SATA SSD cache for 16x faster IOPS. Btrfs file system ensures data integrity. Users value flexibility but note high drive costs. Perfect for SMB storage needs.
Connectivity and Features
Includes 4x 1GbE, 2x USB 3.2 Gen 1, 1x eSATA, and 1x PCIe 3.0 x8 slot for 10GbE/25GbE cards. Supports Link Aggregation and failover. Certified for VMware vSphere, Microsoft Hyper-V, and Citrix. Features AES-NI encryption, Synology DSM OS, and High Availability clustering. The RS1221RP+ has dual 350W PSUs. Users note noisy fans but reliable performance. Ideal for compact rack deployments.
