New RackStation units for High-end Storage

The 2U 12-bay RS3621RPxs and RS3621xs+, and the 3U 16-bay RS4021xs+ are designed for SMBs that require high-performance general-purpose storage. Synology’s newest devices provide a reliable platform for data-intensive applications such as large-scale backup, ISCSi SAN storage, on-premises collaboration solutions, and video surveillance deployments.

“These xs and xs+ series units are versatile, high-capacity units for SMBs and enterprise deployments,” said Julien Chen, Product Manager at Synology Inc. “Their built-in redundant power and Intel® Xeon® processors make them ideal for handling mission-critical data in applications such as large-scale video surveillance, business file servers, backup tasks, office productivity software suites, and as cost-effective virtualization storage,” Chen added.

All three units offer significant performance improvements compared with prior generation units.1 The RS3621RPxs delivers 68% higher, the RS3621xs+ delivers 50% higher, and the RS4021xs+ delivers 21% higher random read IOPS than their respective predecessors.2 The units’ two PCIe Gen 3.0 8x slots enable upgrades with compatible 10GbE NICs3 and/or NVMe SSD cache.3

HAT5300 series HDD for Synology Systems

Synology HAT5300 enterprise SATA hard drives come in 16TB, 12TB, and 8TB models, and are optimized for high-performance and maximum reliability from their Synology deployments. Extensive validation testing for HAT5300 series HDD ensures seamless interaction with Synology systems and DiskStation Manager. The drives are engineered to provide highly stable, high-capacity storage for Synology storage systems, with the added benefit of automatic firmware updates provided through DSM.

“The HAT5300 enterprise hard drives are great for business-critical data that require capacity, reliability, and cost-effective performance,” said Peggy Weng, Product Manager at Synology Inc. “During development we tested the three SKUs for more than 300,000 hours4 to ensure that they deliver absolute dependability for our customers,” Weng said. “We’ve created highly-optimized drives that our customers can rely on to work perfectly with our systems and seamless DSM integration.”

HAT5300 drives deliver up to 274 MB/s sustained data transfer and with DSM-specific optimization, are up to 23% faster in sustained sequential read performance in demanding multi-user environments compared with other similar-class drives.5 With automatic firmware updates through DSM, HAT5300 drives always benefit from the latest firmware enhancements while reducing the work needed by system administrators. Backed by a 2.5 million hour MTTF rating, workload support of 550 TB per year, and persistent write cache technology, HAT5300 series drives are built to excel in 24/7 enterprise environments.

  1. Comparisons conducted against prior-generation RS3617RPxs, RS3617xs+, and RS4017xs+ units.
  2. 4K iSCSI random read IOPS using an aggregated 10GbE connection. Performance figures are achieved in the Synology lab 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.
  3. Compatible NICs include the E10G17-F2, E10G18-T2, E10G18-T1. For the latest compatible devices, check the compatibility list.
  4. Among the HAT5300-8T, HAT5300-12T, and HAT5300-16T drives, 300,000 hours of hard drive tests have been conducted with Synology devices to maximize the compatibility of these drives with Synology devices.
  5. Performance testing was conducted by Synology using 12 drives on an SA3600, configured using RAID 5, against similar class drives (Enterprise) with IOMeter (64KB blocks). Results are for reference only. Actual performance may vary depending on workload, testing methods, and how devices and software are configured.
