![]() Mechanical drives will be marked as deleted, but until they are overwritten, data can still be recovered. This is important when using a mechanical drive, as files are not deleted immediately.

However, TRIM was added shortly after SSDs hit the market and unless you have an early model of SSD, your drive should support TRIM. For those who upgraded later, you have to run trimforce in the terminal with the following command:Īpple does not want to be held responsible if your SSD’s hardware doesn’t implement TRIM correctly and you run into an issue. If your computer came with an SSD pre-installed, you have TRIM enabled. Apple, on the other hand, does not support TRIM on most third party SSDs, and it is disabled by default. ![]() TRIM prevents your drive from making unnecessary writes and being overused.įor Windows, SSDs are usually detected when installed and TRIM is enabled for all drives. Drives without TRIM enabled have to partially move large pieces of information, wipe out all the blocks containing it, and finally, write the new data onto those blocks. Unlike a mechanical drive, when writing new data, an SSD can only write to empty blocks. What is TRIM exactly? TRIM is a command that allows an operating system to inform a solid-state drive which blocks of data are no longer considered in use and can be wiped internally. TRIM is essential for keeping SSDs in tip-top shape.
