How to Ensure TRIM and Health Status of SSD

A solid-state drive or SSD is a data storage device that uses integrated circuit assemblies as memory to store data persistently. SSD are all the rage nowadays, their popularity grows as their cost decreases and capacity expands. SSD are much faster than the traditional hard drive. SSD data is stored onto memory chips and don’t require the physical nature of spinning a disk platter for reads and writes like a traditional hard drive. Unlike the previous hard drive it has no moving parts and boost faster. They are much stable and resilient. But, a proper care of SSD is also necessary. Here is the tutorial to ensure the health and TRIM of SSD.

TRIM is a firmware feature found on all recently available solid state drives on Windows 7 OS that targets in maintaining tip-top performance throughout the life of the drive. TRIM command allows an operating system to inform a solid-state drive (SSD) which blocks of data that are no longer considered in use and it is free to wipe that block internally.

Previously, the SSD had their tools and utilities that were to be ran periodically by the user. But, TRIM has lifted that burden from the user.

How to Detect the TRIM is working properly or not

  • Open a Command Prompt window with Administrator privileges
  • Execute the command fsutil behavior query DisableDeleteNotify

If the Disable Delete Notify = 0 , then it indicates that TRIM is enabled and functioning correctly. Conversely, 1 indicates TRIM is disabled and therefore not available to the SSD. Windows enable the TRIM feature by itself. If it’s not enabled it could be a result of improperly installed or otherwise outdated controller drivers. But, you can try to enable TRIM manually in that same command prompt window with the command fsutil behavior set disablenotify 0.

Ensure Health Status of an SSD

Every electronics item has a particular lifespan. SSD has a limited number of writes available before predicted failure. An SSD may be rated and warranted for 1,000,000 writes Orignally, hard drives’ lifespans were measured in hours of use; that was understood by everyone. To predict the life left from the number of writes on an SSD Windows provides an application named SSDlife that leverages the SMART subsystem of the SSD to return useful statistics on the health of the device. All spinning hard drives incorporate the SMART technology. However, because SSD is a different type of device it requires a slightly different interpretation of SMART metrics.

On the first launch of SSDlife it will scan the system for any and all attached SSD. It will return with a populated tab for each device found – on which you can see all sorts of information and metrics including: free and used space, hours of operation, and estimated lifetime. The information is represented in a simplified manner into a simple bar graph that visualizes the overall health of the drive from 0-100.

The procedures described above will ensure the good health and TRIM of the SSD on your system.
