How to turn off Windows compression? A Compressed hard drive is very nice if you want to maximize the space on your disk, but a drawback is that all disk storage operations take more time. With a very fast CPU in your system, this might not be a problem, but if you want to maximize your PC performance you do not use disk compression. To turn off Windows compression on a disk, right-click the drive and select Properties in the popup menu. In the disk properties dialog, uncheck the Compress drive to save space checkbox and click OK.
