Hardware Comparison
Processing Power
Synology DS224+/DS423+: Intel Celeron J4125 quad-core processor at 2.0GHz (burst to 2.7GHz). This x86 architecture supports hardware transcoding for Plex, Docker containers, and virtual machines. The processor includes Intel UHD Graphics 600 for 4K transcoding.
WD My Cloud EX2 Ultra: Marvell Armada 385 dual-core ARM processor at 1.3GHz. Limited to basic NAS functions - no hardware transcoding, no Docker, no VMs. Adequate for file serving but struggles with intensive tasks.
WD My Cloud PR2100: Intel Pentium N3710 quad-core at 1.6GHz. Supports hardware transcoding and runs Plex reasonably well, but the older 2016 architecture limits expandability compared to Synology.
Winner: Synology - significantly more powerful processor enables features WD My Cloud simply cannot run.
Memory
Synology's 2GB DDR4 RAM (expandable to 6GB) outperforms WD's 1GB DDR3 in the EX2 Ultra. The PR2100's 4GB is competitive but uses older DDR3L and cannot be upgraded.
More RAM matters for running multiple apps simultaneously, photo indexing (especially AI-powered facial recognition in Synology Photos), and handling more concurrent users.
Winner: Synology (expandability) or WD PR2100 (out of box)
Software & Features Comparison
| Feature | WD My Cloud OS 5 | Synology DSM 7.2 |
|---|---|---|
| User Interface | Simple, consumer-focused | Professional, highly customizable |
| Mobile Apps | My Cloud app (basic) | DS file, photo, video, audio (comprehensive) |
| File Sync | WD Sync | Synology Drive (Google Drive alternative) |
| Photo Management | Basic galleries | Synology Photos with AI face recognition |
| Docker Support | ❌ No | ✅ Yes (Container Manager) |
| Virtual Machines | ❌ No | ✅ Yes (Virtual Machine Manager) |
| Surveillance | Basic (Milestone ARCUS) | Professional (2 free camera licenses) |
| Third-Party Apps | ~15 apps | 200+ packages |
Plex & Media Streaming
Synology: Native Plex Media Server package with hardware transcoding on Intel-based models. DS224+ and DS423+ can transcode 4K HEVC to 1080p for remote streaming. Multiple simultaneous transcodes possible.
WD My Cloud: EX2 Ultra cannot transcode - only direct play/stream works. PR2100 handles transcoding but the older Intel chip limits performance. Both include 3-month Plex Pass trial.
Winner: Synology - superior transcoding performance and native integration.
Backup Solutions
Synology Active Backup Suite: PC and Mac backup (unlimited devices), Microsoft 365 and Google Workspace backup, VMware/Hyper-V virtual machine backup, Synology C2 cloud integration, Hyper Backup for NAS-to-NAS replication.
WD My Cloud: WD Backup (Windows), Time Machine support (Mac), basic cloud backup (Dropbox, Google Drive), ElephantDrive integration.
Winner: Synology - enterprise-grade backup at consumer prices.
Price Comparison
Total Cost of Ownership (8TB Usable Storage)
| Configuration | NAS Cost | Drives (2×8TB) | Total |
|---|---|---|---|
| WD EX2 Ultra + WD Red Plus | $170 | $340 | $510 |
| Synology DS224+ + WD Red Plus | $300 | $340 | $640 |
| WD PR2100 + WD Red Plus | $400 | $340 | $740 |
The DS224+ actually costs $100 less than the PR2100 while offering better performance and features. The $130 premium over the EX2 Ultra buys dramatically better hardware.
Who Should Buy What?
Choose WD My Cloud EX2 Ultra If You:

Frequently Asked Questions
Is WD My Cloud being discontinued?
WD continues to sell My Cloud devices, but the product line has seen less innovation compared to Synology. The EX2 Ultra uses the same hardware design from 2016. WD's focus has shifted toward consumer external drives.
Can I use Seagate IronWolf drives in WD My Cloud?
Yes. Despite WD's short compatibility list, IronWolf and other NAS drives work fine in My Cloud devices. WD prefers you buy their Red drives, but any CMR NAS drive will work.
Does Synology require their own drives?
No. Synology supports WD Red, Seagate IronWolf, Toshiba N300, and most other drives. Recent DSM versions (7.3+) have improved third-party drive support, removing previous compatibility warnings.
Which NAS is more reliable?
Both are reliable when using quality NAS drives. Synology's BTRFS file system offers additional protection against data corruption with checksums and self-healing. WD My Cloud uses EXT4, which is stable but lacks these advanced features.
Can I migrate from WD My Cloud to Synology?
Yes. Copy data via network share or external drive. Synology Migration Assistant helps automate some tasks. You'll need to reconfigure backups (WD Sync → Synology Drive) and update remote access (WD cloud → QuickConnect).
Which has better security?
Synology. Offers two-factor authentication, Security Advisor for vulnerability scanning, automatic security updates, Let's Encrypt SSL integration, and firewall rules. WD My Cloud has faced multiple critical security vulnerabilities over the years, though most have been patched.
Final Verdict
| Category | Winner | Why |
|---|---|---|
| Overall Value | Synology DS224+ | Better hardware/software for $130 more |
| Performance | Synology | Faster CPU, more RAM, Docker support |
| Plex/Media | Synology | 4K hardware transcoding |
| Lowest Budget | WD EX2 Ultra | $170 entry point |
| Simplicity | WD My Cloud | Easier setup and interface |
| Future-Proofing | Synology | Better updates and expansion |
Our recommendation: For most users, Synology is the better choice. The DS224+ costs only $130 more than the EX2 Ultra but delivers dramatically better performance, features, and future-proofing. The software ecosystem alone justifies the premium.
WD My Cloud still makes sense for buyers who prioritize simplicity and low cost above all else, or who want a basic backup target without the "power user" features.
