What to Look for When Buying a Synology NAS

CPU: Intel vs AMD

Choose Intel if:

  • You plan to use Plex with transcoding
  • You stream to devices that can't direct play
  • Hardware transcoding is a priority

Choose AMD if:

  • You run Docker containers or VMs
  • You need 10GbE upgrade capability
  • ECC RAM is important to you
  • You primarily use direct play for media

Number of Bays

  • 2 bays: 4-16TB usable, good for home backup
  • 4 bays: 12-48TB usable, ideal for most users
  • 5+ bays: 32TB+ usable, for business or large media

Tip: Buy more bays than you think you need. Storage needs always grow, and it's easier to add drives than replace the NAS.

RAM

  • 2GB: Basic file storage, limited apps
  • 4GB: Multiple apps, Docker, Surveillance Station
  • 8GB+: Heavy Docker use, VMs, large Surveillance deployments

Note: Most Plus models support RAM upgrades. Check your model's max before upgrading.

Networking

  • 1GbE: ~110MB/s max, sufficient for most home users
  • 2.5GbE: ~280MB/s max, good upgrade with affordable switches
  • 10GbE: ~1,000MB/s max, for video editing and power users

Recommendation: If you edit video or transfer large files frequently, prioritize a model with 10GbE upgrade capability (DS923+, DS1522+).

Frequently Asked Questions

What is the best Synology NAS for home use?

For most home users, the DS224+ ($299) or DS423+ ($450) are ideal. Both have Intel CPUs for Plex transcoding, run Synology Photos for family photo sharing, and offer excellent DSM software. Choose 2-bay (DS224+) for basic needs or 4-bay (DS423+) for larger media libraries.

Should I buy DS923+ or DS925+?

Buy DS923+ if you want 10GbE upgrade capability or find it discounted. Buy DS925+ if you want built-in 2.5GbE, the newest hardware with longest support, or need more CPU threads for Docker/VMs. Both are excellent - the DS923+ offers better expandability while the DS925+ has better out-of-box networking.

Which Synology is best for Plex?

The DS423+ ($450) is the best Synology for Plex. Its Intel J4125 CPU has Quick Sync hardware transcoding that handles 4K to 1080p conversion smoothly. AMD-based models (DS923+, DS925+) work with Plex but only for direct play - they cannot transcode efficiently.

Is Synology worth it over QNAP or DIY?

Yes, for most users. Synology's DSM software is the best in the industry - polished, secure, and regularly updated with 10-year support. QNAP offers better hardware specs but has had security issues. DIY (TrueNAS, Unraid) is more flexible but requires technical knowledge. Synology is the "Apple" of NAS - it just works.

How many bays do I need?

For home use: 2 bays (4-16TB usable). For media servers: 4 bays (24-48TB usable). For business: 5+ bays (40TB+ with SHR-2 redundancy). Remember that SHR uses one drive for redundancy, so 4x 8TB gives you 24TB usable, not 32TB.

Do I need Synology-branded drives?

No. After the DSM 7.3 update (October 2025), third-party drives from WD, Seagate, and Toshiba work perfectly on all Synology models. Use NAS drives like WD Red Plus or Seagate IronWolf - they're 25-50% cheaper than Synology HAT drives with identical performance.

Synology Software: Why It Matters

One of the biggest reasons to choose Synology over competitors is DiskStation Manager (DSM) - their operating system.

Key DSM Features

  • Synology Drive: Dropbox-like file sync across devices
  • Synology Photos: Google Photos alternative with AI face recognition
  • Hyper Backup: Comprehensive backup to cloud or local storage
  • Surveillance Station: Professional video surveillance (2 free licenses)
  • Active Backup for Business: Free PC/server backup solution
  • Container Manager: Docker containers made easy
  • Virtual Machine Manager: Run VMs on your NAS

DSM Security Features

  • 2-Factor Authentication: Extra security layer
  • Auto-block: Blocks IPs after failed login attempts
  • Firewall: Built-in network protection
  • Security Advisor: Scans for vulnerabilities
  • Snapshot Replication: Point-in-time recovery (Btrfs)
  • Encryption: Volume and shared folder encryption

10-Year Software Support

Synology provides software updates for approximately 10 years from release. This is significantly longer than competitors:

Brand Typical Support Period
Synology ~10 years
QNAP ~5-7 years
UGREEN Unknown (new brand)
Asustor ~5-6 years

Expansion Options

If you outgrow your initial storage, many Synology models support expansion units:

Expansion Unit Compatibility

NAS Model Expansion Unit Additional Bays Max Total Drives
DS923+ DX517 (eSATA) +5 bays 9 drives
DS925+ DX525 (USB-C) +5 bays 9 drives
DS1522+ DX517 (eSATA) x2 +10 bays 15 drives
DS1621+ DX517 (eSATA) x2 +10 bays 16 drives

Note: It's generally better to buy a larger NAS than rely on expansion units. Expansion units add cost ($500+) and complexity.

Common Mistakes to Avoid

Mistake 1: Buying Too Few Bays

Storage needs always grow faster than expected. If you're deciding between 2 and 4 bays, get 4 bays. The price difference is minor compared to replacing the entire NAS later.

Mistake 2: Using Desktop Drives

Desktop drives (WD Blue, Seagate Barracuda) are not designed for 24/7 NAS use. They'll fail faster and may use SMR technology that causes severe slowdowns. Use proper NAS drives.

Mistake 3: Skipping Redundancy

A single drive with no redundancy means one failure = complete data loss. Always use SHR or RAID for important data, and remember: RAID is not backup.

Mistake 4: Forgetting Backup

Your NAS needs to be backed up too. Use Hyper Backup to cloud storage (Backblaze B2, AWS S3) or an external drive. Follow the 3-2-1 rule: 3 copies, 2 media types, 1 offsite.

Mistake 5: Ignoring Network Speed

A fast NAS on a slow network is a waste. Ensure you have at least gigabit networking throughout your home/office. Consider 2.5GbE or 10GbE for video editing and large transfers.

Where to Buy Synology NAS

  • Amazon: Wide selection, competitive prices, fast shipping
  • B&H Photo: Often has good deals, no tax in most states
  • Newegg: Frequent sales, bundle deals
  • Synology Authorized Resellers: Sometimes include drive bundles
  • Costco: Occasional deals for members

When to Buy

  • Best deals: Black Friday, Prime Day, holiday sales
  • Avoid: Right before new model announcements (April-May typically)
  • Refurbished: Synology refurbs are rare; buy new for warranty

Future-Proofing Your Purchase

When investing in a Synology NAS, consider these future-proofing factors:

Storage Growth

  • Buy more bays than needed today - You can add drives later
  • Consider maximum drive capacity - Most models support up to 20TB+ drives
  • Expansion units available - But it's better to buy bigger from the start

Network Speed Evolution

  • 2.5GbE is becoming standard - Consider DS925+ or DS425+ for built-in 2.5GbE
  • 10GbE for power users - Choose DS923+ or DS1522+ with PCIe slot
  • Wi-Fi 7 compatibility - Faster wireless may benefit from faster NAS speeds

Software Support Longevity

  • Newer models = longer support - DS925+ will get updates until ~2035
  • DSM major versions - New features typically require recent hardware
  • Security patches - Critical for network-connected devices

Total Cost of Ownership

Beyond the NAS itself, budget for these additional costs:

Initial Setup Costs

Component Budget Typical Premium
4-Bay NAS $450 (DS423+) $599 (DS923+) $700 (DS1522+)
4x 8TB NAS Drives $560 $600 $720
UPS (Optional but recommended) $60 $100 $200
RAM Upgrade (Optional) $0 $50 $150
10GbE Card (Optional) $0 $0 $120
Total $1,070 $1,349 $1,890

Ongoing Costs

  • Electricity: ~$20-50/year (NAS uses 20-40W typical)
  • Cloud backup: ~$60-120/year (Backblaze B2, ~$5-10/TB/year)
  • Surveillance licenses: ~$50 per additional camera
  • Drive replacement: Budget for one drive every 3-4 years

Final Recommendations Summary

After analyzing every current Synology model, here are our final recommendations for February 2026:

If You're a First-Time NAS Buyer

Start with the DS224+ ($299). It's affordable, capable, and perfect for learning. You'll get hardware transcoding for Plex, Synology Photos for family photo management, and all the DSM features that make Synology great. Add 2x WD Red Plus 8TB ($300) for a complete setup under $600.

If You Want the Best All-Around NAS

The DS923+ ($599) remains our top pick. The 10GbE upgrade path via PCIe makes it future-proof for serious users. It's proven, reliable, and often discounted. Pair it with 4x WD Red Plus 8TB for 24TB usable storage.

If You Want the Latest 2025 Hardware

The DS925+ ($640) is the newest 4-bay with built-in 2.5GbE networking. You'll get the longest software support (~10 years) and more CPU threads for Docker/VMs. Just note it lacks the 10GbE upgrade path of the DS923+.

If Plex Transcoding is Critical

The DS423+ ($450) is your best bet. Its Intel J4125 CPU with Quick Sync handles hardware transcoding that AMD models cannot do. If transcoding is a must-have, this is the only choice in the mid-range.

If You're Running a Small Business

The DS1522+ ($700) offers 5 bays for SHR-2 protection, 8GB ECC RAM, 10GbE upgrade capability, and enterprise features like Active Backup for Business. It's the sweet spot for growing businesses with serious data protection needs.

No matter which model you choose, Synology's excellent DSM software and long-term support make it a sound investment for your data storage needs.
