WebDAV is one of those protocols that has been around forever but never quite dies — and in 2026 it's getting more relevant, not less, because AI inference data, photo backups, and SMB replacements all need a way to make remote storage feel like a real local disk.
This week I tested the two most popular options side-by-side on the same NAS, the same gigabit network, the same workload: RaiDrive Pro ($69.99/year) and ScsDriver ($9.99/year).
TL;DR
If you just need one or two mount points and never push past 50 GB, RaiDrive's free tier is enough. If you're running a real home-lab NAS with 4 TB+ data, multi-protocol mounts, and 24/7 uptime, ScsDriver wins on price, stability, and UI simplicity.
Speed
Same gigabit network, both sides capped at Samba throughput on the NAS.
| Workload | RaiDrive Pro | ScsDriver |
|---|---|---|
| Single 4.7 GB ISO write | 108 MB/s | 102 MB/s |
| 1,000 × 1 MB files | 4m12s | 4m18s |
| 4 GB random read | 105 MB/s | 98 MB/s |
The difference is real but small. For most people, you won't notice.
Stability (24/7 test, 1 week)
I left both mounted for seven days running an automated workload every 4 hours.
- RaiDrive: disconnected twice, auto-reconnected both. Noisy system tray icon.
- ScsDriver: zero disconnects. Quiet.
Chinese filenames & long paths
Both fine. Windows built-in "Map Network Drive" chokes on UTF-8 filenames. Don't use it for anything serious.
UI / usability
RaiDrive's UI is dense — once you have 8+ mount points, finding the one you want becomes a chore. ScsDriver's interface is closer to a Settings panel: clean list, search box, one click to test the mount.
Price
This is the headline:
| RaiDrive Pro | ScsDriver | |
|---|---|---|
| Annual | $69.99 | $9.99 |
| Monthly equivalent | $5.83 | $0.83 |
| Free tier | ✅ 3 mounts | ❌ 7-day trial |
7x price difference. For a homelab user on a tight budget, this is the entire conversation.
When to pick which
- RaiDrive: Enterprise, need SMB/NFS support, complex auth (NTLM, Kerberos), need paid support contract.
- ScsDriver: Home NAS, personal cloud (Google Drive / OneDrive mounted), cost-sensitive, want a stable long-running mount.

What I actually use
For my own setup — Synology DS220+ with 2x 4TB, gigabit uplink, mostly Plex + photo backup — I went with ScsDriver. The price difference bought me a second SSD for cache.
If you have an enterprise use case, or you need SMB/NFS more than WebDAV, RaiDrive Pro still has features ScsDriver doesn't pretend to compete on. Pick the right tool.
