Optimizing and maintaining your SSD

So you have just purchased your CAD Workstation which has a Solid State Drive (SSD). Here are a few tips and tricks on how to optimize the SSD. 

Turn off Disk Defragmenter

Standard Hard Drives need to be Defragmented to essentially organize files on your PC for optimal performance. Disk defragmentation is unnecessary on a Solid State Drive as it writes the data in a random manner anyways. Hence this option is irrelevant and defragmenting your SSD can actually slow it down.

To turn off Disk Defragmentation.

1. Go to: Start > Control Panel > Performance Information & Tools > Advanced Tools > Open Disk Defragmenter

2. (For Windows 7) Go to "Configure Schedule" hence uncheck your SSD from "Run on Schedule"

    (For Windows 8 & 10) Go to "Change Settings" and if Run on Schedule is checked, uncheck it.

Turn off Superfetch

In order to reduce constant read/write cycles which reduce the lifespan of your SSD and slow it down, disable Superfetch. To do this: 

1. Press Win+R and run Services.msc, in the menu search for Superfetch.

2. Doubleclick on Superfetch 

3. On the "Startup Type "  pull down menu select "Disabled"


Turn off Prefetch

Prefetch loads pieces of program files into RAM. By disabling this feature, you free up your system memory. To disable Prefetcher perform the following:

1. Win+R and run "regedit"

2. Select the file path "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\Memory Management\PrefetchParameters"

3.Right-click on both EnablePrefetcher and EnableSuperfetch

4. Select Modify on each of these to change the value from 1 (or 3) to 0

5. Restart your machine.


Turn off Hibernation (Optional)

Unless you use the Hibernation option you may turn this option off. When you put the PC to sleep the hardware is on and consumes the electricity. When you choose to Hibernate it turn off all the hardware entirely. When you switch on hibernation mode, everything from the ram is copied to the C drive wearing out the SSD. 

1. Run Command Prompt, Right click "cmd" and run as administrator.

2. In the command prompt enter "powercfg.exe /hibernate off" and hit enter.


Disabling the Page File

If you are running out of  space on your SSD you may disable your Paging file in order to recover some of that taken up by the paging file. It is not recommended unless you have more than 8GB of RAM installed in you PC.

The paging file operates in a way that it moves some of the data from your RAM back to your hard drive, placing it in the page file. This file is a form of virtual memory. While writing this data to your hard disk and reading it back later is much slower than using RAM, it’s back-up memory – rather than throwing potentially important data away or having programs crash, the data is stored on your hard drive.


1. Go to Advanced System Settings

2. Go to "Settings" in Performance section.


3. Go to Advanced & Change, then select, "No Paging File"
