The video discusses NTFS file compression in Windows, highlighting its potential benefits in saving disk space but warning about performance implications and CPU bottlenecks. The speaker compares NTFS compression with ZFS and BTRFS, finding the latter to be more effective. They conduct tests on file copying speeds and game performance, concluding that modern games may not work well with compression. While NTFS compression offers some space savings, especially with deduplication, it is not recommended for critical OS files due to potential negative impacts on performance. In general, NTFS compression is deemed to have limited space savings and performance drawbacks compared to other compression methods like ZFS. The speaker suggests using NTFS compression sparingly, mainly for low input-output files like log files.

In this segment of the video, the speaker discusses NTFS file compression in Windows. File system-level compression allows for compressing files transparently to save disk space. While this feature can improve performance by utilizing the CPU for compression, the effectiveness varies based on implementation. The speaker compared NTFS compression with ZFS and BTRFS, noting the latter had better compression capabilities. Through testing, the speaker found that enabling compression on an external SSD led to significantly slower speeds during file copying, indicating potential CPU bottlenecks. Despite recommendations to leave compression on all the time, the speaker emphasizes the need for further testing due to performance implications, CPU usage, and potential file fragmentation issues, especially with larger files.

In this segment of the video, the speaker explains how NTFS compression works, utilizing algorithms similar to LZ77 and newer compression methods in Windows 10. The speaker conducts a file copy test using a high-end desktop CPU (AMD Ryzen 5950X) and compresses a 81.3GB folder to 44.9GB on NTFS. Various file copy tests are conducted between compressed and uncompressed folders, showing different speeds (e.g., 106 MB/s, 88 MB/s). The speaker notes that while read speeds are acceptable, write speeds are slow. An observation is made about the inconsistent speed display in the Windows file copy dialogue. The speaker also explores performance implications on game storage, using the same desktop setup for analysis.

In this segment of the video, the creator discusses compressing their Steam game library to save space. They tested the performance impact of NTFS compression on game downloads and loading times, concluding that modern games don’t perform well with compression due to significant slowdowns. They also examined the space-saving aspect of NTFS compression, finding that the best space savings came from NTFS deduplication. Deduplication was noted to offer good space savings and performance in past experiences, although it is not easily accessible on Windows 10. Additionally, the creator explored the use case of a small boot drive, testing common programs in a virtual machine with a 32GB volume.

In this segment of the video, the speaker compares the disk space usage between a system with NTFS compression and without compression. The results show a slight space savings with compression, but NTFS compression cannot compress most OS files. They recommend using the compact.exe program to compress OS files for significant space savings, but warn that it may hurt performance. Overall, the speaker found NTFS compression to have poor performance and limited space savings, unlike ZFS compression, which is usually recommended. They suggest considering NTFS compression for low IO files like log files, but otherwise advise leaving it off.
