The defrag functions of Defraggler should not be used on solid-state drives since they may shorten the lifespan of these drives or even damage them outright while also having no impact on the drive's performance.Lesson 18: How to Defragment Your Hard Drive We don't recommend using Defraggler's defrag function on SSDs: This can take longer than a TRIM and puts a bit more wear and tear on the drive, but it is a good alternative for configurations that do not support TRIM. This means that there's a supply of fresh, 'empty' blocks available, and you can write data to these. To stop this from happening, Defraggler can overwrite all the free space on the drive with zeroes. If no TRIM function is available, the SSD can't erase the blocks in advance. If there are no blank blocks left, the blocks must be erased to provide space for the new data. This is at its quickest when the block is blank (zero-filled).

SSD performance is based on the time taken to write to a block. This is by using a method called Zero Filling. Is TRIM not supported by your SSD or by your operating system?įear not, as Defraggler can use an alternative method to help improve the write speed performance of your SSD. Note: You can use our Speccy software to determine if your current configuration supports TRIM. Older SSDs can't support the TRIM function, and TRIM is only supported on Windows 7 and later operating systems.

For TRIM to work, both the operating system and the SSD must support the feature, and it has to be enabled within the operating system itself. This allows the SSD to write to a completely blank block. When you delete a file on an SSD, a TRIM command is also sent to wipe the marked block clean. First, it must erase all the data before writing the new information to the block.

Unlike a standard HDD, it cannot do this in one action. Instead, the space it occupies is marked by the operating system as “not in use.” When the operating system needs this space, it overwrites it. However, if you delete this file, it doesn't get instantly removed. When you write a file to a new SSD, it gets written to the block at full speed. Defraggler can optimize your SSD using a TRIM function. Defraggler's TRIM function helps rejuvenate tired SSDs:Īs with a standard HDD, the performance of an SSD deteriorates with use over time.
