Optimize Windows for SSD: Guide

In this comprehensive tutorial, we’ll show you step-by-step how to fine-tune your operating system for maximum performance and longevity. From enabling TRIM and disabling disk defragmentation to optimizing power settings and minimizing unnecessary writes, we’ll cover everything you need to know to ensure your SSD operates at its peak efficiency.

By the way, if you installed a fresh copy of Windows (from the scratch) onto your SSD, many services and parameters will be configured automatically during the installation (this is why many specialists recommend a new Windows installation when adding an SSD to your rig).

Optimization of Windows for an SSD will not only allow to extend your drive’s lifetime but also to improve Windows performance. As to optimization procedures, the advice and recommendations in this article are relevant for Windows 7, 8 and 10.

What Should Be Checked Before Optimization?

Make Sure That ACHI SATA Mode Is On

It is quite easy to see what mode is enabled for the controller, just by looking at BIOS settings. If the disk mode is set as ATA it has to be switched to ACHI.

Yet there are two important things to keep in mind:

  • the first – Windows won’t boot as it doesn’t have the necessary drivers. You will have to either install them beforehand or just reinstall Windows (which is both easier and more preferable, in our opinion);
  • the second – your BIOS might not have ACHI mode available (though, it applies mostly to pretty old PCs). In this case, you will probably have to update BIOS (or at least check at the manufacturer’s website to see if their new BIOS supports this function).

It would be useful to enter Device Manager (it can be found in the Windows Control Panel) and open the tab containing information on IDE ATA/ATAPI controllers. If you can see a controller with a name that includes “SATA ACHI” then everything is all right.

Optimize Windows for SSD: Guide

The AHCI mode is required for supporting normal operation of TRIM in the SSD.

TRIM is a command of the ATA interface required for Windows to transfer to the drive some data on which blocks are no longer needed and can be overwritten. The matter is that the principle of file deletion and space formatting in HDD and SSD differs. With the use of TRIM, SSD performance in increased, with a steady wear-out pattern of the drive memory cells. TRIM is supported by Windows 7, 8, 10 (if you are using Windows XP I recommend upgrading your OS or buying a drive with hardware-based TRIM).

Make Sure That TRIM Support Is Enabled in Windows

In order to check if Windows support for TRIM is enabled, you can just launch command prompt as administrator. Then type in the command fsutil behavior query DisableDeleteNotify and press Enter.

Enter command: fsutil behavior query DisableDeleteNotify

If DisableDeleteNotify = 0 (as shown in the picture) – then TRIM is enabled and you needn’t enter anything else.

If DisableDeleteNotify = 1 – then TRIM is disabled; you can enable it with the command: fsutil behavior set DisableDeleteNotify 0.

Then check it once more with the command: fsutil behavior query DisableDeleteNotify.

Disable File Indexing

This is the first thing I recommend because this function has been created for HDD in order to accelerate access to files. However, an SSD is fast enough by itself and this function is merely useless.

After all, disabling this function reduces the number of write sessions to your drive which means extending its lifecycle. To disable indexing go to SSD properties (you can start Explorer and go to “This PC” tab) and uncheck the box next to “Allow files on this drive to have contents indexed in addition to file properties.”

Local Disk (C:) Properties

Disable Windows Search

This service creates a separate index of files which helps the system to find certain files and folders quicker. An SSD is fast enough and many users just don’t apply this function so it would be better to disable it.

First of all, open Control Panel / System and Security / Administration Tools / Computer Management

Then, search the Services tab for Windows Search and disable it.

Disable Windows Search

Disable Hibernation Mode

Hibernation mode allows saving the contents of RAM to the hard disk drive which helps the PC to quickly return to its previous state when switched on again (applications launched, documents open etc).

When using an SSD this function becomes not so important. First of all, Windows starts much faster with an SSD, so there’s little point in saving its previous state. Secondly, extra write and overwrite cycles may influence the life of your SSD.

Disabling hibernation is quite simple – just launch the command prompt as administrator and type in the command powercfg -h off.

Enter command: powercfg -h off

Disable Disk Auto Defragmentation

Defragmentation is a useful operation for HDDs that helps to improve their performance a little. However, it has no benefits for an SSD because it is designed in a different way.

The speed of access to all SSD cells containing data is the same, and it means the speed of access will be the same, no matter where “pieces” of files are stored!

Moreover, relocating these “pieces” from one place to another increases the number of write/overwrite cycles which eats up the SSD lifetime.

If you have Windows 8/10 there is no need to disable defragmentation. The built-in disk optimizing software (Storage Optimizer) will select the necessary option automatically.

If you have Windows 7 you should go to defragmentation utility (Disk Defragmenter) and disable it.

Disk Defragmenter

Disable Prefetch and SuperFetch

Prefetch is a technology that helps the computer to accelerate launching of frequently used programs. It is done by loading them into RAM beforehand. A special file with such name is created in the hard disk.

As SSDs are pretty fast this function is better to be disabled as it won’t give you any more speed.

SuperFetch is a similar function, the only difference being that the computer is trying to guess what programs you are likely to start and loads them into RAM in advance (this is also recommended to be disabled).

To disable these functions you should use the register editor.

Run: regedit

When you have it started, go to the following link:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters

Then, in this part of the register you need to find two parameters: EnablePrefetcher and EnableSuperfetch. Their value should be set at 0. By default, they are set at 3.

Regisrty Editor

By the way, if you install a fresh copy of Windows on an SSD, these parameters will be configured automatically. Frankly speaking, it does not always happen flawlessly: sometimes there can be errors if your system contains both SSD and HDD drives.

Utilities for Automatic Optimization of Windows for an SSD

Some people would choose to do manually every step described in this article, and some others would love to use special utilities for fine tuning of Windows. Such utilities are known as tweakers.

Many users also recommend transferring browser cache, paging files, Windows temporary folders, system backup copies (and other data) from SSD to HDD (or even disabling these functions at all).

Then why have an SSD? To make sure your system boots up in 10 seconds? In our view, an SSD is necessary to accelerate the general system performance (the main goal), reduce noise, extend the working time of a laptop when on battery power etc.

But when applying all these settings we can reduce all advantages of an SSD to nothing.

This is why when we talk about optimization and disabling unnecessary functions we mean only what cannot accelerate your system in any way but can affect the lifecycle of your SSD and therefore safety of your data.

That is because if an SSD goes wrong when depleting its resources, no data recovery software can help you.
