I do not normally recommend enabling the Force Trim command, as this can potentially corrupt or damage data being stored on the drive. So I asked Crucial about whether I could or should use the TRIM function on my M4 drive. There is also some debate as to whether Garbage Collection on its own is sufficient to keep an SSD drive in tip top condition. The SSD can then manage its available storage more intelligently. TRIM ensures the physical NAND memory locations containing deleted files are erased before you need to write to them. This causes your SSD to slow down over time unless TRIM is enabled. The longer you leave it the less likely it will be possible to recover the file.With flash memory, it’s actually faster to write to empty memory than to write to full memory, which means that the memory should first be erased and then written to. Unerase type apps depend on this fact so that if you should delete a file in error you should resolve that asap.
They don't actually delete the file, they tell the system that the space that was occupied by the 'deleted' file is now available for reuse and so can be overwritten. Nothing special there then, after all that is how rotational drives work. The SSD then knows that the file is deleted and it can erase the file’s data from its flash storage. When the OS, (Mac, Windows or Linux) uses TRIM with a solid-state drive, it sends a signal to the SSD every time you delete a file.
Trim enabler mac free mac os#
Cindori used to make Trim Enabler as a free piece of software but as the mac OS has developed the needs for Trim software have changed.
