How to Fix a Slow SSD: The Simple Trick to Restore Speed

Solid State Drives (SSDs) are designed to provide significantly faster boot times and a more responsive overall system experience compared to traditional Hard Disk Drives (HDDs). However, these drives can encounter performance degradation over time, leading to sluggish read and write speeds.

Maintaining optimal SSD performance involves a combination of storage management, system configuration, and the verification of specific drive commands.

Managing Disk Capacity

One of the primary causes of SSD slowdown is a lack of available storage space. When a drive reaches high capacity—specifically around 90 percent—performance issues often become noticeable.

To resolve this, users should delete unnecessary files and folders to free up space. Disabling the hibernation feature in Windows can help reclaim disk space.

To disable hibernation, users can open the Command Prompt (CMD) as an administrator and execute the command powercfg -h.

The Role of the TRIM Command

The TRIM command is essential for maintaining SSD speed. If this command is not running, the drive can become painfully slow.

Users can verify if TRIM is enabled by running the Command Prompt as an administrator and entering fsutil behavior query DisableDeleteNotify.

The system will return a numerical value to indicate the status of the command:

• A result of 0 indicates that TRIM is enabled.
• A result of 1 indicates that TRIM is disabled.

If the command is disabled, it can be enabled by entering fsutil behavior set DisableDeleteNotify 0 in the administrator Command Prompt.

System Power Settings

Power management settings can also impact the speed of an SSD. In Balanced mode, the drive may not receive sufficient power to operate at its optimal speed.

Switching the system to Best Performance mode favors performance over energy savings, which can help the SSD maintain its intended speed.

Additional Troubleshooting and Optimization

Beyond basic space management and TRIM verification, other technical factors can influence SSD health and speed.

• SSD firmware updates: Updating the drive’s firmware can resolve known bugs and improve efficiency.
• Write caching: Adjusting how the system handles data writes can impact perceived performance.
• Thermal throttling: Overheating can cause the drive to slow down to protect the hardware.
• Health checks: Regular monitoring of the drive’s health can identify failing components before they cause significant slowdowns.

By addressing these areas, users can restore the read and write speeds of their storage devices and ensure the system remains responsive.
