Txij li thaum Apple thawj zaug muab Macs nrog SSDs (khoom-xeev drives), lawv tau suav nrog kev txhawb nqa rau TRIM, ib txoj hauv kev uas pab cov haujlwm ua haujlwm pub dawb. Nws kuj tseem pab kom lub neej ntev ntawm kev tsav tsheb thiab txhawb kev ua haujlwm tau zoo.
Cov ntaub ntawv ntawm no siv tau rau Mac OS X Lion (10.7) thiab tom qab ntawd, nrog rau tag nrho cov versions ntawm macOS mus txog qhov tseeb [tam sim no, 10.15 (Catalina)].
The TRIM Command
Cov lus txib TRIM pab OS ntxuav cov ntaub ntawv hauv cov blocks uas tsis xav tau ntxiv lawm. Qhov no ua kom zoo tshaj qhov kev sau ntawv ntawm SSD los ntawm kev khaws ntau cov ntaub ntawv pub dawb los sau rau. Nws kuj tseem tiv thaiv SSD los ntawm kev nruj heev hauv kev ntxuav tom qab nws tus kheej uas nws ua rau hnav ntawm lub cim xeeb chips. Ua li no, tiv thaiv kev ua tsis tiav ntxov ntxov.
TRIM tau txais kev txhawb nqa hauv OS X Lion (10.7) thiab tom qab ntawd rau txhua qhov tsav, tab sis nws tau qhib los ntawm lub neej ntawd tsuas yog ntawm Apple-muab SSDs. Nws tsis paub meej tias vim li cas Apple txwv TRIM txhawb nqa txoj hauv kev no, tab sis qhov kev txawj ntse ib txwm yog qhov kev siv TRIM yog nyob ntawm SSD cov chaw tsim khoom, thiab txhua tus siv txoj kev sib txawv TRIM. Xws li, Apple xaiv siv TRIM nkaus xwb ntawm SSDs uas nws tau lees paub.

Cov khoom siv hluav taws xob no siv Apple's built-in TRIM kev txhawb nqa thaum tshem tawm lub peev xwm ntawm OS los xyuas seb SSD puas nyob ntawm Apple cov npe ntawm cov tuam txhab pom zoo.
