#FREE MAC TRIM ENABLER FOR MAC#
The purpose of "trim" is to indicate that a sector doesn't hold useful data, and thus there's no need to copy its contents to another sector if the block which contains it gets recycled. Download TRIM Enabler 1.3 Build 7 for Mac - Patch utility designed to enhance the performance of your Macs SSD by optimizing the management of free and used storage space. If it later becomes necessary to recycle the blocks to which those pages had been copied, it will be necessary to copy the data yet again. I want to do whichever is best, this kext patch, or the trim force command. If, however, it's necessary to free up space when every block has at least some useful pages in it, it will be necessary to copy all of the useful pages from a block somewhere else before the block can be reused. Is this better than using trimforce I just did a clean install of 10.13.2 and my new nvme drive has trim enabled by default, but my SATA SSDs (previous 10.12.6 OS drive, and a windows 10 drive) now show trim is not enabled, though it was under 10.12.6. If a all of the pages in a block have been superseded by pages elsewhere, the block may be safely erased. When software asks to write a 512-byte "disk sector", the drive will write the data to a new page and update some "index" data which tracks which physical page holds the latest version of each disk sector, after which the page which held the previous version will be available for recycling. It's not possible to erase pages individually the devices are limited to erasing a block of data at a time. The flash chips used in silicon disks are subdivided into large blocks, each of which contains many 528-byte pages.
