Overview

Eight bays unlock more parity options, higher throughput from more spindles, and a longer runway before re-platforming.

This class of NAS suits teams with growing datasets, media workflows, and multi-user access.

Who should buy the DS1825+

Pick this model when you need capacity and concurrency without jumping to rackmount gear.

• Studios with active projects plus long term archives
• Small businesses with several users accessing the NAS at once
• Buyers who want snapshots and replication with longer retention

Spec planning checklist

A short plan avoids rebuild surprises and performance bottlenecks.

• Capacity targets for one and three years with 20 percent buffer
• Drive model short list and acoustic targets
• NVMe cache or SSD volume policy and when to add it
• Network path including 2.5 GbE or 10 GbE and switch ports
• UPS size, rack or shelf placement, and airflow

Storage layout patterns

Choose a layout that balances rebuild risk, performance, and cost.

• RAID 6 with NAS HDDs for strong protection and predictable cost
• RAID 10 for faster random I/O at the expense of usable capacity
• SSD volume for hot assets; HDD array for bulk capacity

Networking and performance

Plan the end to end path. Throughput depends on NICs, switch backplane, cabling, and client adapters.

Avoid half upgradable chains. A single 1 GbE link in the path will cap transfers.

Key apps and use cases

Limit app sprawl and focus on proven value.

• Synology Drive for team sync and sharing
• Active Backup for Business for endpoint protection
• Hyper Backup for offsite copies to a second NAS or cloud
• Surveillance Station for SME camera fleets

Backup and resilience plan

Follow the 3-2-1 rule with clear roles for snapshots, replication, and offsite copies.

• Hourly or daily snapshots for rollbacks
• Nightly replication to a second device
• Cloud or offsite copy for disaster recovery
• Test restores monthly to verify integrity

Setup tips

Update DSM, set alerts, and document the config. Label drive bays and keep spare screws and cables on hand.

FAQs

Answers to frequent planning questions.

• Do I need 10 GbE? Only when clients and switches support it end to end
• Is RAID 6 slow? Sequential throughput is usually limited by network, not parity math
• How do I keep it quiet? Pick low noise HDDs and isolate the NAS from desks
