Self-Hosted Cloud Storage in 2026: The Real Cost Calculator

说明与用途

五年内，自托管 Nextcloud 成本为 1,034.5 美元，而 Dropbox Plus 为 600 美元。对于需要超过 1 TB 并重视隐私的用户，自托管更划算，但需要技术维护。

问题

Determine whether self‑hosted Nextcloud is cheaper than Dropbox Plus over five years for a home user with growing storage needs.

结果

Over five years, self‑hosted Nextcloud costs $1,034.5 versus Dropbox Plus $600, but offers scalable capacity, full privacy, and no vendor lock‑in. The cost advantage appears only if the user needs more than 1 TB and values privacy and speed.

工作流

• Select hardware: Beelink N100 mini PC ($160), 2×8 TB IronWolf NAS drives ($300), UPS ($65), domain name ($60).
• Install Ubuntu Server LTS and Nextcloud (free).
• Configure WebDAV share and install ScsDriver on Windows ($5.5 lifetime).
• Use Tailscale for remote access (free).
• Calculate electricity: 12 W × 24 h × 365 days = 105 kWh/yr → $16.80/yr. Add drive replacement cost ($60/yr).
• Sum 5‑year costs: hardware $585, electricity $84, drive replacement $300, domain $60, ScsDriver $5.5 → $1,034.5.
• Compare to Dropbox Plus: $120/yr × 5 = $600.
• Evaluate trade‑offs: capacity, privacy, speed, vendor lock‑in.
• Decide based on user needs: >1 TB and privacy → self‑host; <1 TB and zero maintenance → Dropbox.
