What’s the best allocation unit size for gaming or video files in Windows 10? Can you change the allocation unit size with/without formatting? Here, this post from MiniTool Partition Wizard explores the detailed information about this topic. You can read this post and find what you want to know.
Allocation unit size, also called cluster size, is the smallest amount of disk space that your system can use for storing a file. An allocation unit can only save a single file even though the file is as small as one byte. Therefore, to use the storage capacity on your hard drive wisely, it’s important to set a proper allocation unit size for various files.
If you often save gaming or video files on the hard drive in Windows 10, you may wonder about the best allocation unit size for gaming/videos. Let’s go through this post to find out the answer.
The Best Allocation Unit Size for Gaming
What’s the Windows 10 best allocation unit size for gaming? Well, in most cases, the 64K is the best. As you know, the game files often take up much disk space. If you use a hard drive with a small cluster size to save game files, a file will occupy many clusters. As a result, it will take a long time to access the large game file, increasing the loading time while playing games.
Therefore, the Windows 10 best allocation unit size for gaming is 64K, enabling your system to access a large file through fewer allocation units.
The Best Allocation Unit Size for Video Files
Like game files, video files are also always big. As for this, we recommend you use 64K as the best allocation unit size for video files as well.
Of course, the number is not absolute and you’d better set the allocation unit size depending on the specific files you store on the hard drive. For instance, if you use the hard drive to save your favorite TV shows or movies, setting the allocation unit size to 2MB might be a better choice.
