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

Whole disk compression is not a good method for growing storage, adding another hard drive or upgrading khổng lồ a larger drive 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 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 laptop.

Only showroom the NTFS compression to lớn Files và 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 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 lớn 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 pagefile.sys. All major operating systems do this. Unix uses a special partition called the swap partition (for the ios và linux fans).

When your computer runs low on hard drive space, windows will adjust the size of how much data this file can hold thus hindering the performance of your computer when it has khổng lồ 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 tệp tin system). When he turned on file compression, it free"d up more room so the swap tệp tin could grow to an optimal size and applications could then be cached again.
