SSD full? Low disk space fix
A full SSD slows everything down. Unlike HDDs, SSDs rely on free blocks for wear leveling and performance. When an SSD is nearly full, write speed drops and lifespan suffers. ClearKun helps you identify and remove the right files to keep your SSD fast and healthy.

問題 · PROBLEM
Why is my SSD full so fast?
SSDs are smaller than HDDs but store the same hidden Windows files. Add app caches, downloads, and game installs, and a 512 GB SSD can fill in months. The result is slower boot times, laggy apps, and reduced drive lifespan.

よくある質問
Frequently asked questions
SSDs are smaller than HDDs and store the same hidden system files. App caches, downloads, and games consume space faster on smaller drives.
Clear caches, temp files, old installers, and unused game files. Use ClearKun to see the largest folders and understand what is safe to remove before deleting.
Yes. SSDs slow down when nearly full because write operations need free blocks for wear leveling and garbage collection.
Keep at least 20-30% free for performance and longevity. If you are below 15%, performance and lifespan suffer noticeably.
Not blindly. System files like WinSxS, pagefile, and hiberfil are protected for a reason. ClearKun explains which are safe to clean and which are not.
SSDs reserve blocks for wear leveling and error correction. A 512 GB SSD often shows around 476 GB in Windows — this is normal.
