Synology Hard Drives & SSDs

A

Synology-branded drives are optimized for DiskStation Manager, rigorously tested for compatibility, deliver consistent I/O performance, feature extended endurance ratings, and include a dedicated RMA process for streamlined support.

A

Consult Synology’s official Compatibility List by selecting your NAS model to view validated HDD/SSD models and firmware versions, ensuring full support for performance, caching, and data integrity.

A

Open Storage Manager, navigate to SSD Cache, select Create, choose SSD slots, configure read-only or read–write mode, set cache size, and apply—your NAS will automatically optimize frequently accessed data.

A

Choose RAID types based on your performance and redundancy needs: RAID 1 or SHR for mirroring, RAID 5/6 for balanced capacity and fault tolerance, and RAID 10 for high IOPS with data protection.

A

Use Storage Manager’s Health Info tab to view SMART attributes, temperature, wear level, and run manual or scheduled extended S.M.A.R.T. tests to proactively detect potential failures.

A

SATA SSDs fit 2.5″ bays for general storage or caching; NVMe SSDs install in M.2 slots to deliver significantly higher sequential throughput and lower latency, ideal for heavy workloads and virtualization.

A

Go to Control Panel > Update & Restore > Drive Firmware Update, click Check, and follow prompts. Firmware updates deliver stability improvements and compatibility enhancements for DiskStation Manager.

A

Select SSDs with at least 0.3 DWPD (Drive Writes Per Day) for typical home or small business use, and 1.0+ DWPD for heavy-write applications such as virtualization and database caching.

A

Mixing is technically possible but unsupported. To ensure maximum reliability, performance, and warranty coverage, Synology recommends using validated drives listed in the official Compatibility List.

A

Allocate dedicated SSD slots for read-write cache, size the cache at 10–20% of total data volume, enable adaptive fetch, and monitor cache hit rates to fine-tune for your workload.

A

Synology provides a 5-year limited warranty on branded HDDs and SSDs, covering manufacturing defects and performance failures when operated under recommended environmental conditions.

A

In Storage Manager, identify the degraded drive, power down if hot-swap is unsupported, replace with an identical or larger drive, then initiate Repair to rebuild the RAID array automatically.

A

Synology supports ext4, Btrfs, and FAT32/NTFS for external volumes. Btrfs is recommended for internal volumes for its snapshot, self-healing, and quota features.

A

Data Scrubbing periodically scans RAID volumes to verify data integrity and automatically repair corrupted blocks using parity information, reducing the risk of silent data degradation.

A

Yes, Synology SSDs adhere to industry SATA/NVMe standards. However, performance tuning and warranty RMA services are optimized when used within Synology NAS environments.

A

With a 0.3–1.0 DWPD rating, Synology SSDs typically last 5–7 years under standard NAS read/write patterns. Monitor wear level and plan replacements when endurance exceeds 80%.
