Synology Plus Series 3.5 Inch SATA HDD
Synology Plus Series Storage for an Always-On NAS Synology Plus Series hard drives provide CMR storage for compatible Synology systems used for shared files, computer backups, media libraries and other everyday NAS workloads. The range combines a 3.5-inch SATA interface with drive firmware management through DiskStation Manager, helping you keep storage maintenance within the same system you use to manage your files. Choose the capacity that fits your NAS model and storage pool. Performance, power and operating limits vary by capacity. Check the exact part number before adding drives to an existing array. Highlights CMR recording: conventional magnetic recording for NAS write workloads. Designed for continuous operation: a storage range for compatible home and small-office Synology systems. Capacity-specific performance: speeds up to 7200rpm and maximum sustained transfer rates up to 295MB/s. Integrated maintenance: supported drive firmware updates through DSM without removing the drive. Three-year limited warranty: manufacturer coverage starting from the purchase date on the receipt. Key Features Storage Matched to Your Synology System Plus Series drives are intended for supported Synology NAS configurations rather than a universal fit for every NAS, server or expansion unit. Match the complete drive model and capacity to the system's compatibility information, including any DSM or drive-firmware requirements. When expanding a storage pool, allow for the selected RAID or SHR layout and existing disk sizes. Raw drive capacity is different from usable storage after formatting, system use and redundancy. Larger replacement drives may require a supported expansion procedure before their extra capacity becomes usable. CMR for Daily Shared Storage Conventional magnetic recording is used across the Plus Series. This suits the repeated writes involved in shared folders, scheduled backups and multi-user access. Synology validates the drives with its storage systems and reports over 500,000 hours of cumulative compatibility and stress testing for the range. A drive's workload rating covers data read, written and verified by the host. It is not a daily transfer guarantee or a substitute for choosing a suitable NAS and storage layout. The 8TB option carries a 300TB/year workload rating; the other listed capacities are rated for 180TB/year. Performance and Capacity for Shared Storage The range offers spindle speeds up to 7200rpm, cache up to 1GB and maximum sustained transfer rates up to 295MB/s. These headline figures describe the top of the range rather than every capacity. Select the capacity you need and allow for the usable space required by the storage pool. Cache, drive construction, acoustics and power demand also differ by model. Allow for these requirements when planning cooling, noise-sensitive placement or a larger storage pool. Network speed and NAS processing can limit real-world transfer rates below the drive's own maximum. Keep Firmware Maintenance in DSM On supported Synology systems, DSM notifies you of available drive firmware updates and provides an integrated update workflow. This avoids removing drives for maintenance with a separate computer and keeps the process alongside the NAS storage-management tools. Drive health monitoring and redundant storage help with maintenance, but neither replaces a separate backup. Keep an additional copy of important files outside the main storage pool and test that it can be restored. Summary Synology Plus Series HDDs suit compatible Synology NAS systems that need CMR storage, continuous operation and integrated firmware maintenance. Select the exact capacity and part number supported by your system, then plan the storage pool around its usable capacity, workload and backup requirements.

Key Features
Storage Matched to Your Synology System
Plus Series drives are intended for supported Synology NAS configurations rather than a universal fit for every NAS, server or expansion unit. Match the complete drive model and capacity to the system's compatibility information, including any DSM or drive-firmware requirements.
When expanding a storage pool, allow for the selected RAID or SHR layout and existing disk sizes. Raw drive capacity is different from usable storage after formatting, system use and redundancy. Larger replacement drives may require a supported expansion procedure before their extra capacity becomes usable.
CMR for Daily Shared Storage
Conventional magnetic recording is used across the Plus Series. This suits the repeated writes involved in shared folders, scheduled backups and multi-user access. Synology validates the drives with its storage systems and reports over 500,000 hours of cumulative compatibility and stress testing for the range.
A drive's workload rating covers data read, written and verified by the host. It is not a daily transfer guarantee or a substitute for choosing a suitable NAS and storage layout. The 8TB option carries a 300TB/year workload rating; the other listed capacities are rated for 180TB/year.

Keep Firmware Maintenance in DSM
On supported Synology systems, DSM notifies you of available drive firmware updates and provides an integrated update workflow. This avoids removing drives for maintenance with a separate computer and keeps the process alongside the NAS storage-management tools.
Drive health monitoring and redundant storage help with maintenance, but neither replaces a separate backup. Keep an additional copy of important files outside the main storage pool and test that it can be restored.
