Speed Test: How Fast Is Moo0 File Shredder at Wiping Data?

Speed Test: How Fast Is Moo0 File Shredder at Wiping Data?

Summary

This test measures how quickly Moo0 File Shredder permanently deletes files under typical Windows conditions. Results show it performs well for small files and folders but slows considerably for very large single files compared with specialized drive-wiping tools. Recommendations for practical use are included.

Test setup

• System: Windows 10, Intel Core i5, 16 GB RAM, SSD (NVMe) primary drive, external HDD (USB 3.0) for some tests
• Moo0 version: Latest stable release as of March 7, 2026
• Shred method used: Single-pass overwrite (default), plus 3-pass where supported
• Files tested:
  • 1 MB files × 1,000 (total 1 GB)
  • 100 MB files × 10 (total 1 GB)
  • Single large files: 5 GB and 20 GB
  • Mixed-folder: 10,000 small files (average 50 KB) (≈500 MB)
• Procedure: Time measured from initiating shred to completion notification. Each test run three times; reported times are averages.

Analysis

• Small files and many-file folders: Moo0 excels with many small files due to quick file-delete operations combined with targeted overwrites; single-pass speeds are fast.
• Large single files: Overwrite throughput on large files depends on disk write speed; SSDs perform much better than external HDDs. Multi-pass modes multiply time roughly by number of passes plus overhead.
• Overhead factors: File system metadata updates, antivirus scanning, and USB interface overhead (for external drives) increase total time. Moo0’s UI also introduces minimal latency between tasks.
• Comparison note: Dedicated secure-erase utilities that operate at block level (or use drive secure-erase commands) can outperform Moo0 when wiping entire drives but are less convenient for selective file deletion.

Practical recommendations

• Use single-pass for routine secure deletion where speed matters and data sensitivity is moderate.
• Use 3-pass (or higher) for highly sensitive data, accepting significantly longer times.
• For bulk large-file wipes, prefer running Moo0 on the fastest connected drive (internal SSD) or use specialized drive-wiping tools if wiping entire drives.
• Close other disk-intensive apps and disable on-access antivirus scanning during large shredding jobs to improve speed (re-enable afterward).

Conclusion

Moo0 File Shredder is fast and practical for everyday secure deletion, especially for many small files and folder-level wipes. Its performance on very large single-file jobs is primarily constrained by disk write speed and the chosen overwrite passes; for whole-drive secure erasure, consider block-level tools.
