Should I Compress My Drive to Save Disk Space

Should you compress your drive to save disk space? In general, we do not recommend that you compress operating drives, especially system drives, as this can lead to system instability and poor performance. But some users report getting a lot of benefits from compressing their drives. Before getting into it, we must be clear about one thing.

Compression drives are a double-edged sword with pros and cons.

So you can see that while compressing the OS drive may save you a lot of storage space and possibly even improve performance, the risk involved is not worth it as there are other ways to save storage space while compressing the OS drive. Therefore, it should be a last resort.

Conclusion

For Windows 7 and above, Microsoft natively enables drive compression in its NTFS file system. Therefore, it is easiest to compress the C:/ drive on Windows. All you have to do is format the drive to use NTFS, then go to the properties of your C: drive and check the "Compress contents to save disk space" box to allow transparent file compression. Although your operating system natively supports OS drive compression, keep in mind that it is meant to be used as the last resort and should not be your first choice to save disk space. Please first try to free up more disk space according to the above methods. Don't forget to share this article to help more people in need.

Should I Compress My Drive to Save Space FAQs

In most cases, we don't recommend users save disk space by compressing their drives. These questions below may help you learn more:

1. Can I compress C drive to save disk space?

Yes, you can. You can save even more hard drive space by enabling drive compression, but it doesn't come without a cost. If you compress and use processing power (CPU), every time you access the file, you have to read and decompress the file before you can use it. In addition, every file you save or edit must be compressed, which can take a long time to read.

2. Can I compress my SSD to save disk space?

Yes, you can do that. But we don't recommend compressing SSD drives because compression is not a feature of SSDs. Also, the operating system controls compression and decompression, which puts extra work on the CPU and can cause the computer to run slower.

3. What will happen if I compress my drive to save disk space?

If you have compressed disks, this can have a positive effect on computers with older, slower disks. However, this will also cause the file to be read and decompressed every time the file is accessed, reducing the response speed of the computer's hard disk.
