How DiskWarrior differs is that the writes are dramatically reduced in it. Because writes to SSDs reduce longevity (as bits are forced through the permeable insulating layer at the chip level), "defrag" in Windows is explicitly NOT recommended (too many writes that can damage the SSD). What they don't see is the "defrag" nature of it that is missing from Apple tools. In the other thread ( ) it was noted that someone doesn't see the need for it with newer OSs. It's now about 3 (4?) years since APFS launched and DiskWarrior still doesn't support APFS. ![]() No such API yet exists for APFS, and it is unclear if Apple will make one available.Īlsoft's Disk Warrior still can't rebuild APFS disks (still) The previous thread was closed. It is important to note as well that Techtool Pro uses a low-level API to test, repair, rebuild, and defragment Mac OS Extended volumes. Likewise, while the Volume Rebuild can repair many drives with volume structures problems, a full rebuild that reorganizes the volume structures can only be implemented once Apple provides further documentation. Defragmentation on Solid State Drives in the traditional sense will not be supported, as organizing data on solid state devices only serves to increase wear, and provides no performance benefit. If Apple releases additional documentation that provides sufficient information for manipulating the data directly on disk, we will explore whether a defragmentation feature is feasible for *rotational* APFS drives. The extent of the documentation on the subject so far is a feature flag labeled NX_FEATURE_DEFRAG which indicates whether an APFS container supports defragmentation. The current documentation from Apple does not include sufficient information to write a tool to defragment APFS volumes. While the operating system serves as the 'window' for interacting with drives in many ways, there is no API for dealing with the disk directly. However, the operating system and the file system are, in fact, distinct from one another. It is understandable to conclude that Mojave, or Catalina support and APFS support would mean the same thing. we would like an answer, if Apple has one, or anyone else. I think there are many Apple users that are in the same boat. Here is the last word from TechTool regrading this issue. When Apple decided to change to APFS Techtool Pro 12 stopped working on File Optimization and Volume Optimization. I have been using that product since TT Pro 6. Techtool Pro used to be part of Apple Care.
