Performance - NTFS vs WinBtrfs

Author: theChaosCoderCreated Nov 2, 2017Updated Sep 17, 2026

I couldn't find any benchmarks or any information about the performance of WinBtrfs, so I made a quick test with CrystalDiskMark 5. It seems that winbtrfs has better random writes/reads but lower seq. write/read performance.

Have you made similar observations?
