(If you never access the files, the potential slow-down when accessing them is unnoticeable.) When To Use and When Not to Use NTFS Compression A test by Tom’s Hardware found that it compressed much less than a tool like 7-Zip, which reaches higher compression ratios by using more CPU time. This is especially true as NTFS compression isn’t very aggressive in its compression. On a computer with a slow hard disk and a fast CPU – such as a laptop with a high-end CPU but a slow, energy efficient physical hard disk, you may see faster file loading times for compressed files. The CPU would have to spend some time decompressing the file, but this will happen very quickly – it may even be faster to load the compressed file and decompress it because disk input/output is so slow. If that same file were compressed and took up 4 MB on the disk, the computer would transfer only 4 MB from the disk. ![]() Consider a 5 MB uncompressed document – when you load it, the computer must transfer 5 MB from the disk to your RAM. ![]() Modern CPUs are very fast, but disk input/output speeds haven’t improved nearly as much. ![]() However, this doesn’t necessarily mean it will take any longer to open the file.
