TRIM helps to make Garbage Collection more efficient by preparing invalid data for deletion. When the OS “deletes” data, the data does not actually go anywhere.
The space in which it resides is simply marked as “free space” that may be used later.
By default, the OS doesn’t let the SSD know which data is now free.
TRIM allows the OS to inform the SSD which data is no longer valid, allowing the SSD to skip over invalid data when performing Garbage Collection.
. XP/ Vista : OS does not support Trim command.
Run Performance Optimization using Magician (once every week, or twice a month)
. Win7/Win server 2008 or later version
.. FAT32 is not supported; NTFS is supported
.. TRIM cannot be done, but Enable/Disable is possible.
.. Enable TRIM in Windows : fsutil command
a. Go to All programs > Accessories > Right-click Command Prompt,
and then run with administrator privileges.
Enter b. fsutil behavior query DisableDeleteNotify, and press Enter ->
“DisableDeleteNotify = 0” means Trim is enabled.
If it is not working, enter fsutil behavior set DisableDeleteNotify 0, and then
press Enter to make it work.
. Linux : Using the fstrim command is recommended, but since it may differ for each Linux version,
please refer to Linux websites for details.
. Mac OS : Please contact the manufacturer
