The SSD Optimization Guide Redesigned

1.  ENSURE YOUR COMPUTER IS OPERATING IN AHCI MODE

PREFACE:  Skip this technique if your bios states your system is in AHCI mode. As uncommon as this may seem, not all computers will automatically install a SSD in AHCI mode and the end result will always be a reduction in performance if the system is running in IDE mode. AHCI mode allows for plug and play installation of SATA devices and Native Command Queuing which can provide as much as a 10-15% performance boost in single drive systems.  A system being set up in IDE mode is a common occurrence with those completing their first computer build who have not first educated themselves and properly set up their bios settings.

WARNING: Double check that you have AHCI in your mobo BIOS before changing.  You will NOT be able to boot into IDE mode after changing this setting. This site claims no responsibility for any modifications made as a result of advise afforded herein.

 

 

 

 

 

 

1.  Hit the Winkey + ‘R’ to get you to the ‘Run’ menu.

2.  Type ‘Regedit’.

3. Select the file path:

“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\msahci”

4. Right Click and modify Start from 3 to 0 and Restart.

2. ENSURE CHIPSET DRIVERS ARE UP TO DATE

Ensure your Chipset drivers are up to date by checking with your system or motherboard manufacturers website and seeking the support and drivers page.

This will allow for the efficient managing of data transmission through the SATA bridge and newer drivers may also be released to solve problems discovered with the system after its release.

TRIM is a very important part of SSD maintenance and allows for background wiping of previous deletions to retain SSD performance.

Although both drivers are fully capable of allowing  TRIM to pass to the hardware, testing has shown that the new Intel driver provides performance improvements to RAID.

There are numerous documented tests that show that the new drivers perform ‘wiping’, similar to TRIM’ almost immediately after a deletion is made on a RAID drive, thus restoring performance.

MSAHCI vs INTEL RST

For the typical user, the difference in the performance between Intel Rapid Storage Technology (RST) and native MSAHCI (standard in Win 7) cannot be visually observed in performance.  Our analysis has shown that, although the two are similar in performance, different versions of RST may provide significantly different performance results, some of which may even be lower than AHCI. Our advise for the typical user is to remain with MSAHCI and, for the enthusiast who loves testing and attaining every ounce of performance possible, install Intel RST and determine which version works best for your needs.

3. DISABLE SYSTEM RESTORE

Although not as crucial now as it once was, System Restore allocates restore points within many SSDs that do not work well with the SSD or TRIM.  There have been numerous examples of  System Restore degrading SSD performance significantly within a few weeks and makes it very difficult for TRIM to function.  Disabling System Restore is not only recommended throughout the web, but also, Intel has lately also included this advise with respect to its SSDs.

Disabling System Restore will also return to you a fair amount of ssd storage space. Some time ago, we had published an article discusses these issues and also provides a simple test process to determine if System Restore may be affecting your SSD Performance.

1.  Right click on My Computer and select Properties;

2.  Select System Protection;

3.  Select Configure; and

4.  Select Turn Off System Restore

Great tips! I just bought the Intel X-25 G2. Im removing my cd drive from my 13″ Macbook Pro – 2.26 Core 2. Then adding the SSD in the cd area using a Obtibay enclosure to run the SSD. Ill be loading just Windows 7 on the SSD via bootcamp from my other drive in the machine. The one tip that I keep reading about is the AHCI MODE. There is no bios or at least I dont think so when booting into Windows from a mac. How can I check if Im running in AHCI mode from my mac… Read more »

you should mofity this post because if you disable all the windows searhing and indexing then you cannot do for exmple

1. Type Regedit into the Start Menu box;#
1. Using the Start Menu Search Box, Search CMD;

because it wont be found, so you have to start looking manually for this apps

In windows XP you couldn’t search regedit through start, it can still be easily done by pressing windows button + r, and then type regedit.

Thanks for the great SSD guide.

Do you have any more information on #18?

What are NtfsDisable8dot3NameCreation and NtfsMemoryUsage, what is the effect of these tweaks on the SSD?

Thanks for any details.

There are no effects on the SSD.

NtfsDisable8dot3NameCreation disables the OS ability to create legacy filenames for older applications.

Shinji was right with the ntfsDisable8dot3… It may be noticeable, and older applications mean older than 20 years, that is when that legacy long file names format was used. It creates short name version for every long named file it creates, for any old application that uses that legacy long format system. I imagine the full path counts in the length of the filename, so if you have a application writing files regularly to a folder with a long tree, all of them may be long file names, and all would be forcing the ssd to create 2 names for… Read more »

Hi, thanks for a great guide!
As regards “15. VERIFY TRIM”, would you recommend using the Intel SSD toolbox on a X25 G2 to schedule daily TRIM just in case Win7 autotrimming for some reason fails to work (even though disabledeletenotify=0)?
Thanks!

why disable superfetch?
you did explain the purpose of these up to #15 but after that there’s no explanation.
can you tell me why disabling superfetch is beneficial for ssd?

SITE RESPONSE: There are some that might state that SF adds unnecessary writes to the drive lessening the lifespan but we would not state such as most will never have their ssd reach end life.

as there are no differences with or without SF in SSD use however, why would you want it running. A fine tuned system does not leave things that don’t serve any purpose running.
