What is Trim For SSD
A Trim command which allows an operating system to inform a solid-state drive (SSD) which blocks of data are no longer considered in use and can be wiped internally.Trim was introduced soon after SSD’s started to become an affordable alternative to traditional hard disks. Because low-level operation of SSDs differs significantly from hard drives, the typical way in which operating systems handle operations like deletes and formats resulted in unanticipated progressive performance degradation of write operations on SSD’s
In other words TRIM helps to maintain the performance of solid state drives (SSDs) at an optimal level over the lifetime of the drive. TRIM functions by actively deleting invalid data from the SSD’s memory cells to ensure that write operations perform at full speed
TRIM Support Solid State Drive
TRIM Support Requirements:
- Windows 7 or Windows 8,8.1
- SSD with TRIM enabled firmware
- BIOS setting SATA=AHCI or Auto but not select IDE
Note:-Laptop user don’t worry if your BIOS dose not have setting like AHCI/SATA because most of the Laptop is AHCI enabled like mine HP DV6 and If you are Windows 8.1 user like me then Trim command is already activated by default so no need to change any thing.
How To Check if TRIM Support for SSDs is Enabled or Disabled
- Open a command prompt with admin preference in Windows 7, 8, 8.1
- In the command prompt, copy and paste the command below, and hit Enter.

In my case Trim is Enable by default
Compare the results with following and Enable/Disable the Trim
DisableDeleteNotify=1 (It means TRIM support disabled)
DisableDeleteNotify=0 (It means TRIM support enabled)
How to Enable TRIM Support
- Open an command prompt with admin preference in Windows7,8,8.1
- In the command prompt, copy and paste the command below, and hit Enter.
fsutil behavior set disabledeletenotify 0
How To Disable TRIM Support for SSDs
- Open an command prompt with admin preference in Windows7,8,8.1 >
- In the command prompt, copy and paste the command below, and hit Enter
fsutil behavior set disabledeletenotify 1
Note:-Always Enable the Trim command which give you better performance,better life and health of your SSD
