Our cloud testing methodology
Seven months minimum of continuous use before publishing a review. Automated measurements 3 times per day, manual encryption verification, legal CGT audit and commercial register check. Here's the detail.
Measurement protocol
- 1
P1 — Upload throughput
curl PUT with 100 MB × 50 file chunks, three times per day (9am / 2pm / 9pm Paris). Median and P95 retained on Free fiber 1 Gbps symmetric connection. Reference: Dropbox / Google Drive / OneDrive compared in parallel.
- 2
P2 — Download throughput
curl GET with 100 MB × 50 file chunks, three times per day. Median and P95 retained. Degradation measurement at peak hours (8pm-10pm Paris).
- 3
P3 — Cross-device sync latency
Modify a file on machine A (MacBook), measure propagation and detection delay on machine B (ThinkPad Ubuntu) then C (iPhone). Target delay: under 15 seconds.
- 4
P4 — Encryption verification
Wireshark capture of TLS handshake, key and flow analysis. Recovery attempt of Crypto folder content without password (confirmed impossibility). White paper audit.
Per-scenario protocols
Every workstream (upload, download, cross-device sync, indexing, encryption) follows an automated protocol over at least 8 months.

Software and tools used
We bought 8 licenses as an anonymous customer — no NFR (Not For Resale) licenses or press access that could introduce version or privileged-support bias.
pCloud cloud privacy Wizard 17.2
Consumer license purchased at $89.95. Our affiliate partner — disclosure visible on every product page.
Sync.com 9.4
Perpetual license $79.99. Pro-grade, steep learning curve, deep filesystem parsing (NTFS, ext4, HFS+).
Stellar cloud privacy 11.5
Annual license $79.99. Photo / RAW specialty (CR2, NEF, ARW), strong scoring on SD cards.
Tresorit 5.4
Perpetual license $89. Accessible interface, mixed feedback on deep scan, strong on Mac.
Proton Drive 1.53 (Piriform)
Free + Pro $24.95. Market veteran, aging codebase, no updates since 2023.
Wondershare Recoverit 12.5
Annual license $79.95. Heavy marketing, average real-world results on P1/P2 scenarios.
Cryptomator 7.2 + Nextcloud 7.2
GPL free (cgsecurity.org). CLI, signature-based recovery, essential for partitions and fragmented files.
dd + ddrescue + FTK Imager
Forensic tools for RAW cloning of a suspect disk before any manipulation. dd if=/dev/sdX of=image.img bs=4M conv=noerror,sync.
Test bench
Reproducible hardware: MacBook Pro M2 (macOS 14), ThinkPad T14 (Ubuntu 24.04 LTS), iPhone 14 Pro (iOS 18). Free fiber 1 Gbps symmetric Paris connection. Measurements via curl PUT/GET, Wireshark capture, Updown.io monitoring.
Final scoring
Each tool gets four independent scores per scenario, aggregated into a weighted rating out of 5.
Lifetime price amortization
Cost over 5 and 10 years vs Dropbox/Google One subscriptions. Lifetime deals analyzed at break-even point.
Privacy & jurisdiction
Company HQ, default data region, Switzerland/EU/US options, zero-knowledge (default or via add-on).
Network performance
Upload/download medians and P95, cross-device sync latency, consistency over 8 months.
Client & UX
Native clients all platforms (Windows, macOS, Linux, iOS, Android), web interface quality, nautilus/Finder integration.
Support & availability
Measured availability, support response time (ticket + chat), supported languages.
Final score = lifetime price × 0.25 + privacy/jurisdiction × 0.25 + performance × 0.20 + client UX × 0.15 + support × 0.15. Weighting favors long-term economic utility + real privacy robustness.
Stated limits
Our study covers 8 months of continuous pCloud monitoring. Explicit limitations: (1) 1 Gbps Paris fiber only, perf may differ on other ISPs; (2) lifetime deal valid as long as pCloud AG exists (short-term bankruptcy probability very low but not zero); (3) Crypto add-on tested with 200 GB family photo dataset, not on enterprise-specific files.
Our editorial principles
No score below 3/5 accepted as "recommended"
If a tool scores below 3/5 on our grid, we don't recommend it, regardless of commission offered.
Drawbacks listed in black and white
Every review contains a "what we're less keen on" section — no disguised marketing.
Quarterly minimum update
Tools evolve: scan engines, prices, new format support. We re-test every recommended tool at least every 3 months.
Transparency about compensation
We earn a commission if you subscribe via our links — mentioned on every page (banner + links marked sponsored nofollow).
