Thanks to low-level disk access, parallelization and optimization, DaisyDisk achieves the highest possible speed of scanning. You can analyze your space usage more readily, because it’s almost instant and doesn’t cause distraction from your workflow.

According to our benchmarks, DaisyDisk outperforms any existing disk scanning software by 6 — 32 times.

The scanning time depends on the type of the media, file system and the number of files on the disk:

• HFS+ SSD startup disk: 6-12 seconds
• APFS SSD startup disk: 12-20 seconds
• HFS+ HDD startup disk: 20-40 seconds
• APFS HDD startup disk: 40-60 seconds
• NTFS, FAT, exFAT: 3-5 minutes
• Time Machine: 20-30 minutes

Hidden space is the unaccounted difference between the total used disk space and the total of all files that have been available for scanning.

Built-in QuickLook allows you to instantly preview files of any type — documents, photos, videos etc. — using the Space key on the keyboard.
