Stringent validation testing and NAS-class reliability ensure consistent performance in high-uptime and multi-user environments.
Highlights
- Reliable Always-On Operation
Backed by 1 million hours MTBF and 180 TB/year workload rating - Tested for Maximum Reliability
Stringent validation and up to 300,000 hours of testing ensure reliability in Synology systems - Seamless Firmware Updates
Firmware updates can be performed directly in Synology DSM - Reliable Recording Technology
Conventional magnetic recording (CMR) technology offers consistent performance
Engineered for endurance
Synology Plus Series HDDs are backed by a 1 million hour mean time between failures (MTBF) rating and 180 TB per year workload rating, up to three times the limit of conventional desktop hard drives. Over 300,000 hours of compatibility and stress testing ensure smooth operation even under multi-user workloads.
Convenient Firmware Updates
Users are automatically notified when firmware updates become available for Synology Plus Series HDDs and can update drives seamlessly from DiskStation Manager (DSM) on their Synology storage system, eliminating the need for third-party tools and disk removal for firmware updates.

- Definition of capacity: Hard drives defines a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 = 1,073,741,824 bytes and therefore shows less storage capacity. Available storage capacity will vary based on file size, formatting, settings, software and operating system. Actual formatted capacity may vary.
- “3.5-inch” is the form factor of HDDs. They do not indicate the physical size of the drive.
- Mean Time Between Failure (MTBF) is not a guarantee or 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.
- Workload is defined as the amount of data written, read, or verified by commands from a host system.
- The warranty period starts from the purchase date as stated on your receipt of purchase. Learn more about our limited product warranty policy.
