10GbE Networking for Business
For businesses with 10+ users, 10GbE networking is strongly recommended. Standard gigabit (1GbE) becomes a bottleneck when multiple users access large files simultaneously.
10GbE Benefits
- 10× faster: ~1,000 MB/s vs ~115 MB/s
- Multiple users: No slowdown with 20+ concurrent connections
- Large files: Essential for video, CAD, design files
- VMs: Required for running VMs from NAS storage
Synology E10G22-T1-Mini
10GBASE-T | RJ-45 | Auto-negotiation 1/2.5/5/10GbE | For DS923+/DS1522+
Add 10GbE to your DS923+ or DS1522+ without using the PCIe slot. Simple plug-in installation. Backward compatible with slower networks.

| Year 1 Cost | $1,560 (hardware) | $3,600 (15 users × $20/mo) |
| Year 2+ Cost | ~$100 (electricity) | $3,600/year |
| 5-Year Total | ~$2,000 | ~$18,000 |
| Storage | 24TB+ expandable | 1TB/user (15TB total) |
| Backup | Included (Active Backup) | Extra cost |
| Data Location | On-premises (you control) | Microsoft data centers |
A Synology NAS pays for itself in ~6 months compared to cloud-only solutions.
Frequently Asked Questions
The Synology DS923+ (~$550) is best for most small businesses with 10-25 users. It offers AMD Ryzen power, optional 10GbE networking, NVMe cache support, and expandability to 9 drives. For smaller offices under 10 users, the DS423+ ($470) is a budget-friendly alternative.
It depends on the model and workload. DS423+ handles ~15 concurrent users, DS923+ handles ~30 users, DS1522+ handles ~40 users. With 10GbE networking and NVMe cache, these numbers improve significantly. For 50+ users, consider the DS1823xs+ or rackmount models.
For most small businesses, yes. A NAS costs less over 5 years ($2,000 vs $18,000 for cloud), provides more storage, keeps data on-premises, and includes backup software free. The main trade-off is you’re responsible for maintenance. Many businesses use both — NAS for primary storage, cloud for offsite backup.
For 10+ users accessing large files, yes. Standard gigabit (1GbE) maxes out at 115 MB/s — a bottleneck when multiple users access files simultaneously. 10GbE provides 1,000 MB/s, eliminating slowdowns. The Synology E10G22-T1-Mini ($110) is an easy upgrade for DS923+ and DS1522+.
Use enterprise-grade NAS drives: WD Red Pro or Seagate IronWolf Pro. These offer 5-year warranties, 300TB/year workload ratings, and 24/7 operation certification. The IronWolf Pro includes data recovery services. Avoid consumer drives (WD Blue, Barracuda) for business use.
Yes. Active Backup for Microsoft 365 and Active Backup for Google Workspace are free Synology applications. They back up Exchange, OneDrive, SharePoint, Teams, Gmail, and Google Drive to your NAS. This protects against accidental deletion, ransomware, and provides a local copy of cloud data.
Conclusion
The Synology DS923+ is the best NAS for most small businesses, offering the right balance of performance, expandability, and value. Add 10GbE networking and NVMe cache for optimal multi-user performance. For larger teams, the DS1522+ provides more capacity and expansion options.
