The standard hard disk drive (HDD) has been the predominant storage device for computers for a long time due to its high storage capacity and low cost. The solid-state drive (SSD) is another storage solution that is slowly replacing the majority of hard disk drives.

SSDs use flash memory to deliver important performance gains compared to mechanical hard drives. Since SSDs do not have small moving parts that are prone to failure, they offer a wide range of cost-effective benefits to nearly every computer user.

However, SSDs can greatly slow down due to a variety of reasons over time. If you find yourself in this situation and your SSD is slow, take a look at the solutions listed below.


What can I do if my SSD slows down with time?

  1. Check the TRIM command
  2. Optimize drivers
  3. Enable the AHCI mode
  4. Disable onboard VGA
  5. Configure Boot order
  6. Check the SATA port
  7. Verify the SATA cable
  8. Update your firmware
  9. SSD optimization
  10. Choose the High Power Plan

1. Check the TRIM command

  1. Click Start and in the search bar type cmd
  2. Right-click Command Prompt and click Open as AdministratorCommand-prompt-run-as-administrator (2)
  3. Type fsutil behavior query DisableDeleteNotify and press EnterTRIM command
  4. If you get 0 as a result, it means TRIM is already enabled. If you get 1, please make sure you follow the next steps
  5. Type fsutil behavior set DisableDeleteNotify 0

2. Optimize drivers

  1. Click Start and in the search bar type Defragment and Optimize Drives
  2. Click Defragment and Optimize Drives
  3. Highlight your SSD and click on Optimizeoptimize drives

With Windows 10, Microsoft added the Optimize Drives feature which runs the TRIM command on your SSD. So please check whether Windows is optimizing your SSD.


3. Check that AHCI Mode is enabled

  1. Open Device Manager
  2. Expand the IDE ATA / ATAPI Controllers
  3. If you see AHCI Controller in the list, you have it enabled. In case you see only ATA and IDE words you are likely to have AHCI disabled on your computerdevice manager AHCI

AHCI Mode plays a significant role in maintaining the high performance of your SSD. If this mode is disabled, the computer can encounter crashes or even see the very famous but unwanted blue screen of death.

If AHCI is disabled and you want to enable it on Windows 10, here is what you need to do:

Go to these keys and set the value named Start to 0:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorV

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorAVC\StartOverride

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride

Restart your computer and go to UEFI/BIOS firmware settings to enable AHCI mode. After you save and exit restart your computer once more


 

4. Disable onboard VGA

Many users have reported that once they disabled the Onboard VGA feature, they managed to solve their problem. 

  1. Restart your computer and open BIOS
  2. Navigate to the Advanced BIOS section.
  3. Search for Onboard VGA
  4. Select the Disable option


 

5. Configure Boot order

  1. Restart your computer and boot into BIOS
  2. Change the boot sequence of HDD and SSD by giving first priority to SSD

Another reason why your SSD drive is slow could be that the boot sequence is incorrectly configured. If top priority to boot up is set to hard drive, the fetch and load time for the operating system from an external source will take more time than usual.


 

6. Check the SATA port

Many motherboards come with two different SATA controllers: some are SATA 3Gbps and some are SATA 6Gbps. Make sure you use SATA 6Gbps for connecting your SSD.

In this respect, you should refer to the motherboard’s manual in order to correctly determine it. Moreover, motherboards built on Intel chipset come with the Intel SATA controller.

Make sure you use the Intel controller to connect your SSD as most of the low-speed issues occur due to using a non-Intel controller on a motherboard built on Intel chipset.

Run a System Scan to discover potential errors

Restoro Scan

Run a PC Scan with Restoro Repair Tool to find errors causing security problems and slowdowns. After the scan is complete, the repair process will replace damaged files with fresh Windows files and components.

Also note that the first SATA port has the highest speed, as claimed by most of the tech savvy users.


 

7. Verify the SATA cable

For a better SSD performance, ensure that the cables are not defective or of a poor quality make and that it is well hooked up to the SATA port. Thus, a good tip is to always purchase a SATA cable from a well-known manufacturer.


 

8. Update your firmware

Just like every other piece of computer hardware you own, updating the firmware on your SSD is important as new bugs and problems get identified and resolved.

This may also improve your SSD’s performance, improve drive stability, or improve compatibility with your system.

In order to check if you need to update the firmware, you must first identify the exact firmware that exists on your SSD and then go on the manufacturer’s website in order to check if newer firmware exists for your SSD. If so, you will just have to follow the instructions for updating.


 

9. Optimize your SSD

  1. In the Start menu search for Disk Cleanupdisk cleanup slow ssd
  2. Select the SSD drive and click OK to launch the processslow ssd
  3. Delete the detected junk files
  4. In the Start menu search for defrag and open Defragment and Optimize Drives
  5. Select the SSD drive and click the Optimize button

The SSD accumulates junk just like the rest of your computer over time. Thus, you need to optimize it from time to time in order to bring it to its original shape.

In Windows 10 you can do that very easily by yourself by following the instructions below or you can use third-party software in this respect.


 

10. Choose the High Power Plan

  1. In the Start menu search for power and click on Power & Sleep settings
  2. Select Additional power settings on the right sideadditional-power-settings
  3. Click on Create a Power Plan on the left side and then select High Performanceslow ssd

When you chose the Balanced Power Plan, your SSD will not receive the full power it needs to run at its best capacity especially in case of sharing of other devices such as GPUs. 

All in all, we really hope that this article helped you and you now get to see an improved performance of your SSD. If you have other suggestions.
