#TRIM ENABLER VS TRIMFORCE MAC#
#TRIM ENABLER VS TRIMFORCE MANUAL#
Making manual Terminal intervention mandatory. Manual Terminal TrimForce is required to TRIM the enclosure disks, even the enclosure boot disk is a manual TRIM! Intel and Western Digital units typically TRIM very well, so that omission is very odd. By default, macOS will TRIM only the MacPro internal disk.
#TRIM ENABLER VS TRIMFORCE PRO#
One of our Mac Pro deployments uses an empty APFS formatted internal and boots to an enclosure housing one boot (Intel Series 530 SSD) and one user-data (Intel Series 520 SSD), both disks ship with hard-rubber mantles (durability). TrimForce establishes itself in very different ways for different disk data structures. The SSD doesn’t need to immediately delete or garbage collect these locations it just marks them as no longer valid." "This results in a reduction of the number of erase cycles on the flash memory and enables higher performance during writes. I can say personally came to my own conclusion and enabled TRIM on my OWC Mercury EXTREME Pro 6G 480GB SSD as soon as I installed it new-and no issue to report.Īll drives will fail over time, so always, always have a current backup plan in place no matter what you decide to do moving forward.
I have also read reports here-in the ASC-where SSD that have bogged down over time and use, and by enabling TRIM has miraculously restored speed and performance. OWC a reliable Mac parts suppler says you can or cannot enable TRIM on their SSD-suppossedly they say their SSD do fine without TRIM. I can say new Apple computers that ship w/ SSD have TRIM enabled by default.Īpple just within the last couple OS X, supply the TRIM command in terminal for 3rd party SSD (eliminating the need for 3rd party methods to enable TRIM) this should tell you something about demand of this functionality. There is much information to sift through. And you don’t need TRIM for garbage collection to work-but TRIM makes an SSD’s garbage collection more efficient." "TRIM doesn’t obviate the need for garbage collection-it works with garbage collection to more properly mark pages as stale. You will have to do your own research and make your own decision on the issue-ultimately it is your loss or gain. I was just worried because on few reddit threads, people complained about slow performance and data loss, after they enabled the TRIM.Īre there any noticeable difference in performance, if it remains disabled?Īll new SSD will perform well, it is over time when allocated blocks and pages become used, you start to see a loss of performance. So that means I can just enable it from terminal, and there is no risk. You can read the man page from terminal, copy & paste: System_profiler SPSerialATADataType | grep 'TRIM' Trimforce status from terminal, copy & paste: The SSD doesn’t need to immediately delete or garbage collect these locations it just marks them as no longer valid. This results in a reduction of the number of erase cycles on the flash memory and enables higher performance during writes. The advantage of the TRIM command is that it enables the SSD’s GC (garbage collection) to skip the invalid data rather than moving it, thus saving time not rewriting the invalid data. If yes, should I use this command on terminal: I want an expert opinion on this, Is it really advisable to enable TRIM?
Some are saying enabling it can cause data loss issues, some are saying you have to do it for better performance. My stock HDD died, so I bought a new Samsung 850 EVO 500GB.ĭrive is installed in the system, but I am reading about the TRIM support on third-party SSD's, and I am really confused. I have a MacBook Pro 13" (Mid 2012) with i7, 8GB RAM and OS X El Capitan/macOS Sierra installed.
