By enabling drive sầu compression you would save sầu space on your hard drive, however the benefit is not without cost. Compression uses processing power (CPU). Every time you access a file, it has khổng lồ be read and uncompressed khổng lồ be worked with. Every file you save or edit will also have sầu to lớn be compressed.

Whole disk compression is not a good method for growing storage, adding another hard drive or upgrading to lớn a larger drive sầu is a better choice.

Not that whole disk compression is bad, there are definite advantages in the right situations. However, "what if" is not one of them.


Compression can have a positive effect on a computer with an older, slower disk. The CPU may have sầu enough horsepower so that doing decompression và compression on read/write is faster than letting the drive read the raw data. It has definitely speeded up my 5 yearold máy tính xách tay.


Only add the NTFS compression lớn Files & folders where you read the data most of the time. DON"T ENABLE it for folders where you write data very often. With information being compressed on the fly, you"re consuming more of an SSD"s available write cycles than if you were writing the files uncompressed. This could have negative sầu implications on the drive"s endurance.


I don"t think that compression would be all that bad on an SSD. Your operating system uses a temporary holding area for data that it needs to fetch when applications are loaded. Compressed files are decompressed and are loaded into this holding area. In Windows, this tệp tin is typically found on the root (C: presumably) of the drive. This file is called pagetệp tin.sys. All major operating systems do this. Unix uses a special partition called the swap partition (for the tiện ích ios and linux fans).

When your computer runs low on hard drive sầu space, windows will adjust the kích thước of how much data this file can hold thus hindering the performance of your computer when it has lớn shrink it because of limited resources. This is probably why hlintrup said he noticed a performance increase for his computer. He was probably out of space (hence why you would compress your file system). When he turned on tệp tin compression, it free"d up more room so the swap tệp tin could grow to an optimal form size & applications could then be cached again.
