11. Synology DS225+ – WARNING: Synology Drive Restriction
+ The Good
- ”Decent
- The Bad
- ”ONLY
I must address a critical limitation of the DS225+ that affects its value proposition for small businesses. This model ONLY works with Synology branded hard drives, which significantly limits your options and increases long-term costs.
Unlike previous Synology models that accepted third-party NAS drives from Seagate, Western Digital, and Toshiba, the DS225+ locks you into purchasing Synology’s more expensive proprietary drives. This restriction has frustrated many long-time Synology users who have existing investments in third-party drives.
Even more concerning, existing drives from older Synology NAS units only work in read-only mode when migrated to the DS225+. This means you can’t expand, repair, or upgrade storage pools with your existing drives – you must purchase all-new Synology branded drives.
The 3.6-star rating (unusually low for Synology) reflects customer dissatisfaction with this restriction. The 26% one-star reviews specifically mention the drive compatibility limitation as a dealbreaker.
Hardware-wise, the DS225+ offers decent performance with up to 282/217 MB/s sequential read/write throughput. The Intel Celeron processor is more powerful than what’s found in the budget DS223. But these advantages are negated by the ecosystem lock-in.
I cannot recommend this model for most small businesses unless you’re starting from scratch and willing to accept Synology’s drive pricing. The DS223 or competitors without drive restrictions offer better value and flexibility.
Who Should Buy?
Virtually no one should buy this model given the restrictions. The only exception might be businesses that exclusively use Synology branded drives and don’t mind the premium pricing.
Who Should Avoid?
Everyone else. The drive restriction makes this poor value compared to Synology’s own DS223 or third-party alternatives.

Who Should Buy?
Businesses with 15-50 employees needing high-performance storage with growth potential. Ideal for creative agencies, video production, or any data-intensive business.
Who Should Avoid?
Small businesses on a budget who don’t need the performance capabilities. The DS423 or DS923+ offer better value for typical office workloads.
Understanding Why Small Businesses Need NAS?
A NAS (Network Attached Storage) is a dedicated file storage device that connects to your business network, allowing multiple users and devices to store, share, and backup data centrally with built-in redundancy and security features.
The business case for NAS has never been stronger in 2026. Cloud storage subscriptions that seemed reasonable when you had 50GB of data become expensive burdens at 5TB. I’ve seen marketing agencies spending $400 monthly on cloud storage that could be replaced with a $500 NAS investment.
Data security is another compelling reason. With a NAS, your data stays on your hardware. You control access, you control backups, and you control compliance. For businesses handling sensitive client information, this control matters increasingly under regulations like GDPR and industry-specific requirements.
Real-World Savings: A law firm I consulted was paying $360 monthly for cloud storage. After investing $800 in a Synology NAS with 20TB of storage, they recouped their entire investment in under 3 months. Over 5 years, they’ll save over $20,000.
Collaboration improves dramatically when files are centrally located. Version control becomes manageable. No more emailing documents back and forth with confusing filenames like “final_v2_REAL_final.doc”. Team members always access the latest version from the shared drive.
How to Choose the Best NAS for Your Small Business?
Quick Summary: Match NAS capabilities to your business size and needs. Most businesses with under 15 employees do well with 2-4 bay models in the $300-600 range. Prioritize expandability, brand reliability, and software features over raw specifications.
Solving for Growth: Consider Drive Bays Carefully
The number of drive bays determines both your storage capacity and your RAID options. More bays give you more flexibility for future expansion without replacing the entire NAS.
For businesses with 5 or fewer employees, a 2-bay NAS provides adequate capacity for documents, emails, and basic file sharing. RAID 1 mirroring protects against single-drive failure while giving you usable capacity equal to a single drive size.
Businesses with 5-20 employees should consider 4-bay models. These enable RAID 5 or RAID 10 configurations that provide better capacity efficiency alongside redundancy. You also gain the ability to mix drive sizes using Synology’s SHR or similar technologies.
Solving for Performance: Look Beyond Network Speed
Don’t get caught up in the 2.5GbE vs 1GbE marketing unless your network infrastructure supports it. Many small businesses still have Gigabit switches throughout their office, in which case a 2.5GbE NAS provides no benefit.
CPU and RAM matter more for most business workloads than network speed. An Intel Celeron processor with 8GB RAM will feel faster in daily use than an ARM-based chip with 2.5GbE networking, especially when running applications or serving multiple users.
Solving for Reliability: Brand Reputation Matters
Forum discussions consistently show Synology as the most recommended brand for small businesses. The combination of reliable hardware, excellent software, and responsive support creates peace of mind that matters when your business data is at stake.
QNAP offers better hardware specifications at similar price points but has a steeper learning curve. Asustor provides good value with HDMI output for media-focused businesses. UGREEN is a newcomer delivering impressive value but lacks the long-term track record of established brands.
Solving for Software: Ecosystem Features Count
Your NAS hardware is only as good as the software that runs it. Synology’s DSM is widely regarded as the most user-friendly NAS operating system, with over 100 applications available in the package center.
Consider what applications your business needs. Virtualization support for running test environments. Surveillance station for security cameras. Mail server for self-hosted email. VPN server for secure remote access. These software capabilities extend the value of your NAS beyond simple file storage.
Solving for Support: Warranty and Resources
Business deployments demand better support than home use. Look for manufacturers that offer at least 3-year warranties. Check response times for technical support. Verify that documentation and community resources are available.
Synology’s reputation for support quality is a significant reason businesses choose their hardware despite premium pricing. When something goes wrong with business-critical data, you want responsive support and clear documentation.
NAS vs Dedicated Server for Small Business
Many businesses wonder whether a NAS is sufficient or if they need a proper server. The answer depends on your specific requirements, but for most small businesses, a modern NAS provides equivalent functionality at lower cost and complexity.
| Factor | NAS System | Dedicated Server |
|---|---|---|
| Initial Cost | $200-1,200 | $1,500-5,000+ |
| Power Consumption | 20-60W | 150-500W+ |
| Setup Complexity | Low | High |
| Maintenance | Minimal | Ongoing IT burden |
| Noise Level | Quiet | Often loud |
| Windows Server Licensing | Not required | $500-1,000+ |
| Virtualization | Basic support | Full support |
For typical small business needs – file sharing, backups, basic applications – a NAS delivers equivalent functionality with lower operating costs and less complexity. Consider a dedicated server only if you need heavy virtualization, specific Windows Server applications, or database workloads that exceed NAS capabilities.
RAID Configuration for Business Data Protection
RAID (Redundant Array of Independent Disks) protects against data loss when drives fail. Choosing the right RAID level is critical for business data protection.
| RAID Level | Min Drives | Redundancy | Capacity Use | Best For |
|---|---|---|---|---|
| RAID 0 | 2 | None | 100% | Temporary scratch data (not business critical) |
| RAID 1 | 2 | 1 drive | 50% | Small offices, simple redundancy |
| RAID 5 | 3 | 1 drive | (N-1) drives | Most small businesses (3+ bays) |
| RAID 6 | 4 | 2 drives | (N-2) drives | Critical data, larger arrays |
| RAID 10 | 4 | 2 drives | 50% | High performance + redundancy |
Important: RAID is NOT backup. RAID protects against drive failure but not against accidental deletion, ransomware, or disaster. Always implement a separate backup strategy following the 3-2-1 rule: 3 copies of data, 2 different media types, 1 offsite.
Security Best Practices for Business NAS
Implementing proper security protects your business data from external threats and internal accidents. Many businesses learn this lesson only after a security incident.
- Enable firewall and auto-block: Most NAS operating systems include firewalls that can automatically block IP addresses after failed login attempts. Enable this feature immediately after setup.
- Use strong passwords and 2FA: Require complex passwords for all user accounts and enable two-factor authentication wherever supported. Default passwords should be changed before connecting the NAS to any network.
- Disable unused services: If you don’t need FTP, Telnet, or SSH, disable them. Each enabled service is a potential attack vector. Only activate features your business actually uses.
- Keep firmware updated: NAS vendors regularly release security patches. Install these promptly, but check forums first to ensure updates don’t introduce new bugs.
- Implement snapshots: Btrfs and ZFS filesystems support snapshots that capture your data state at specific points in time. These protect against ransomware by letting you roll back to before the infection occurred.
- Regular backup testing: Backups are only valuable if they work. Test your restore process quarterly to ensure you can actually recover from a disaster.
Frequently Asked Questions
Which NAS is best for small business?
The Synology DS923+ is the best overall NAS for small business due to its reliability, expandability, and proven software ecosystem. For budget-conscious businesses, the UGREEN DXP2800 offers excellent value with modern 2.5GbE networking and 8GB of RAM at a lower price point.
Is QNAP or Synology better?
Synology is generally better for small businesses due to its intuitive DiskStation Manager software and responsive support. QNAP offers better hardware specifications at similar prices but has a steeper learning curve and a more complex interface. Choose Synology for ease of use and QNAP for maximum hardware value if you have technical expertise.
What are the downsides of NAS?
NAS downsides include upfront hardware costs, technical setup requirements, ongoing maintenance responsibilities, and potential noise in quiet office environments. NAS also requires planning for drive failures and implementing proper backup strategies. Unlike cloud storage, you’re responsible for your own data protection and disaster recovery planning.
Is Synology good for small business?
Synology is excellent for small business and consistently ranks as the most recommended NAS brand by IT professionals. The DiskStation Manager software is enterprise-grade yet accessible to non-technical users. Synology’s extensive application ecosystem, reliable hardware, and responsive support make it the safest choice for business-critical data storage.
How many bays do I need for business NAS?
Most small businesses with 5-15 employees find 2-4 bays sufficient. Two bays work for basic file sharing using RAID 1 mirroring. Four bays enable RAID 5 or RAID 10 for better capacity efficiency and are recommended for businesses planning growth. Only businesses with extensive storage needs should consider 5+ bay models initially.
What RAID level should small business use?
Small businesses with 2-bay NAS should use RAID 1 for drive mirroring. For 3-4 bay NAS, RAID 5 provides single-drive redundancy with better capacity efficiency. RAID 6 or RAID 10 are appropriate for 4+ bay systems storing business-critical data where maximum redundancy is worth the capacity tradeoff.
Can a NAS replace a server?
A NAS can replace a file server for most small businesses, providing file sharing, backup, and basic application services. However, a dedicated server remains necessary for heavy virtualization, Windows Server applications, or database workloads requiring enterprise SQL Server licensing. Modern NAS with Docker support can handle light virtualization and container workloads.
Final Recommendations
After testing these NAS systems extensively and analyzing thousands of customer reviews, the Synology DS923+ remains my top recommendation for most small businesses. The combination of reliability, software quality, and expandability justifies the investment for companies that need storage they can depend on.
Budget-conscious businesses should seriously consider the UGREEN DXP2800. The 2.5GbE networking, 8GB of DDR5 RAM, and dual M.2 NVMe slots provide specifications that typically cost much more. UGREEN has delivered a genuinely compelling value proposition that challenges established brands.
Avoid the Synology DS225+ due to its drive restriction. The requirement for Synology-branded drives negates the value for most small businesses. Choose the DS223 instead for better flexibility at a lower price point.
Investing in proper NAS storage pays dividends for years. The businesses I’ve helped transition from cloud storage to on-premises NAS consistently report improved productivity, reduced costs, and greater control over their data. Start with a 2-bay model if you’re uncertain, but plan for expansion as your data needs grow.
