Solid State Drive (SSD) Tweaks for Windows 7

By: tecmo34

December 19, 2010

This HowTo is to provide the common tweaks used to optimize your new SSD for Windows 7. I

would recommend checking the performance of your SSD before and after these tweaks to see

how they impact your performance. I recommend using AS SSD Benchmark to check yourperformance.

Warning! The reader takes full responsibiity for any damage that may occur to their PC or

hardware by follwing these recommended tweaks. These are just recommendations to improve

the performance of the SSD but are not required if your SSD is functioning correctly.

Step 1. SATA Controller set to AHCI Mode:

During the installation process, you want to ensure your BIOS are set to AHCI for the SATA

controller to enable AHCI. AHCI is needed for native TRIM support utilized by a SSD.

If you have already installed the OS in IDE mode, it is recommened to switch to AHCI after

completing the steps listed in this Windows Article: http://support.microsoft.com/kb/922976, if your BIOS support AHCI.

Step 2. Verify TRIM is Enabled

Verifing TRIM will confirm that the TRIM commands are being sent from Windows to the SSD.

How to Verify TRIM is Enabled

In the start menu search box, type" cmd";

Right click the cmd program and select Run as Adminstrator; and

In the command line type "fsutil behavior query DisableDeleteNotify".

if DisableDeleteNotify = 0 TRIM is Enabled.

If DisableDeleteNotify = 1 TRIM is Disabled.

When typing in the command window, don't include " " when typing.

Step 3. Disable System Restore

System Restore on a SSD can degrade the SSD performance over time and make it very

difficult for TRIM to work. It is recommended to disable System Restore to prevent this and to

regain valuable SSD storage sapce.

How to Disable:

Right click on My Computer and select Properties;

Select System Protection;

Select Configure; and

Select Turn Off System Restore.

Step 4. Disable Drive Indexing

With the access times of a SSD (0.1 ms for most), there is no need to index the drive for

quicker response times, like with a standard hard drive.

How to Disable:

Go into My Computer;

Right click your SSD and select Properties; and

Un-check the box marked "Allow files to have contents indexed in addition to file properties".

A popup screen may appear, stating there is an error applying attributes, this is normal and

you should select "Ignore All" and continue.

requirements. In case it doesn't, you'll want to disable this feature, as defraging your SSD is

not a good thing!!

How to Disable:

Go into My Computer;

Right click your SSD and select Tools tab;Select the box Defragment Now;

without watching your RAM usages prior to implementing.

no real benefit to a SSD due to it's quick load times.
