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 và uncompressed to lớn be worked with. Every tệp tin you save or edit will also have to lớn be compressed.

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 & 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 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 to fetch when applications are loaded. Compressed files are decompressed và are loaded into this holding area. In Windows, this tệp tin is typically found on the root (C: presumably) of the drive. This tệp tin is called pagefile.sys. All major operating systems vì this. Unix uses a special partition called the swap partition (for the ios and linux fans).

When your computer runs low on hard drive space, windows will adjust the kích thước of how much data this tệp tin 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 tệp tin system). When he turned on tệp tin compression, it free"d up more room so the swap file could grow lớn an optimal size and applications could then be cached again.
