Synology hard drives are the result of deep co-engineering with leading drive vendors and refined through real-world deployment scenarios. The firmware is intelligently tuned for NAS workloads, with adaptive behaviors that optimize performance in RAID environments. It offers more efficient handling of RAID parity gaps, reducing latency and improving sequential throughput.
- Performance testing was conducted by Synology using 12 drives on an RS2423RP+, configured using RAID 5, against similar class drives (Enterprise NAS/NAS) with FIO (1 MB blocks). Results are for reference only. Actual performance may vary depending on workload, testing methods, and how devices and software are configured.
- Performance testing was conducted by Synology using 8 drives on a DS1821+, configured using RAID 5, against similar class drives (Enterprise NAS/NAS). Results are for reference only. Actual performance may vary depending on workload, testing methods, and how devices and software are configured.
- Based on actual Synology support statistics over the past few years, the use of validated drives results in nearly 40% less storage-related issues and faster issue diagnostics and resolution. The average firmware update time for Synology drives is based on tests conducted using an RS2821RP+ unit fitted with 16 Synology HDDs. For 3rd-party drives, the average update time was calculated by multiplying the time required for updating a single drive installed on a RS2821RP+ unit by 16.
- Model specifications are subject to change without advance notice. Refer to website for the latest information. Product images are for illustrative purposes only. Actual product may appear with different labeling or housing, which do not affect the performance characteristics of the product.
Please note: Mean Time Between Failure (MTBF) is not a certified estimate of product life; it is a statistical value related to mean failure rates for a large number of products which may not accurately reflect actual operation. Actual operating life of the product may be different from the MTBF.
