Since it can be difficult to identify your problem, we offer our advice in a simple order, from the simplest to the most complicated. Hopefully your SSD will be back up and running at full speed in no time.
Full SSDs Slow Down – Free Up Space To Improve Performance
The less space there is on your SSD, the slower the performance. However, it is not as bad as you might think these days. Older SSD technology had this problem, unless you have an older SSD, we are talking 2010, this will not be a problem.
However, if your SSD has a capacity of 90 or more, you may experience some performance issues. At this point you should make some space.
Your SSD can be difficult to maintain when using a smaller storage capacity. Often the best solution is to move most of your data to a larger 1TB hard drive. They are very cost effective and still offer reasonable speeds for basic performance. If you don’t have a free hard drive, you only need to free up 10% of your storage space in the meantime.
You can check your memory capacity by pressing the Windows key, typing PC, and clicking This PC.

Change To High Performance Mode – For Laptops
Here is a possible quick fix. Please switch to high performance mode by following the steps below.
Press the Battery option in the bottom right of your screen.
Drag the slider to Best performance on the right side.

- Next, Press the Windows Key type Power & Sleep in the Windows Search menu.
- Click Power & Sleep Settings
- Click Additional Power Settings.

- On the new tab, click Create a power plan on the left side.

- Choose High Performance and then click Next. Choose your sleep settings and then click create.
Reduce Startup Apps
By reducing the applications that start when your computer starts, your computer’s startup time improves. Although SSDs can read and write data faster, dozens of startup applications slow down startup time.
To reduce the number of applications that start on first startup, do the following.
- Press the Windows Key.
- Type Startup and click on Startup tasks.
- Go through the list and untoggle apps you don’t want at startup.
- Extra tip: Turn off as many high impact apps as possible.
Check For Viruses
If viruses or malware are running in the background, your system resources may be unnecessarily high. Run a virus scan.
Disable Ultra Low Power States

Ultra-Low Power States, or ULPS for short, is a power-saving mode that can affect your performance and startup times. This is a feature of AMD graphics cards in Crossfire that can sometimes result in slow startup times.
Please note that this will not be a problem for you if you are using NVIDIA or have a single AMD graphics card.
Next, I will explain how to disable it. Follow the steps carefully.
- Press Windows Key + R to open the Run box.
- Type Regedit and press enter.
- Click Yes if prompted.
- Press Ctrl+F to open the Find prompt.
- Type EnableULPS and click Find.
It may take some time to find the EnableULPS registry key. Once it appears, double click the EnableULPS value and change it from 1 to 0.
