SSD Tips and Tweaks

ocz vertex 3 ssd

Looking for a few tips to optimize your OCZ SSD? I’ve got them here. Results can vary and some tweaks might work better for some than others, especially taking into consideration one’s computing habits and system setup. Of course, keep tabs on the tweaks you’ve made to your computer, just in case you ever need to revert back to its previous settings (if the results aren’t to your liking). But I hope they are! :)

Verification of ACHI Mode

Make sure your SATA controller is set to AHCI mode (you can do so in your BIOS). AHCI is needed for native TRIM support in Windows 7. It’s recommended to run your SSD in AHCI mode to enable TRIM to do its job.

Click on the Start > Control Panel > Device manager > IDE ATA/ATAPI controllers > Locate an AHCI controller > If present, the system is in ACHI mode, if not, the system is currently not in ACHI mode.

Check TRIM

TRIM should be automatically enabled in Win 7, but if want to double check, follow these steps:

Click on the Start Menu > Type CMD in the search box > Right click CMD icon > Run as Administrator > Type the following command: “fsutil behavior query DisableDeleteNotify”, Press Enter.

If the result is “0″, TRIM is working properly.

If the result is “1″, TRIM is disabled.

Type the following command to enable TRIM: “fsutil behavior query|set DisableDeleteNotify = 0″

We all know that we shouldn’t defrag our SSDs because defragging it just causes unnecessary writes to the drives, lessen the lifespan of your SSD. So here are the steps to turn defragmentation off.

Turn Off Disk Defragmenter Schedule

Click on the Start Menu > All Programs > Accessories > System Tools > Disk Defragmenter > Click on the Configure schedule button > Uncheck the Run on a Schedule box > Click OK > Close the window.

Disable Disk Defragmenter

Click on Start Menu > Right-Click Computer > Manage > Services and Applications > Services > Find and Right-Click Disk Defragmenter > Find Startup type > Select Disabled > Click OK.

Disable Drive Indexing

With super fast read times, indexing the drive is almost unnecessary and can cause multiple needless writes to your SSD. Indexing will benefit those looking for more endurance over performace from your SSD. If you’re someone who has a large drive and constantly searching for e-mails and files, then disabling it may not be the best idea. On the other hand if you’re someone who rarely uses search option, you may benefit from it.

Click on Start Menu > Right-Click Computer > Manage > Services and Applications > Services > Right-Click Windows Search > Properties > Find Startup type > Select Disabled > Click OK. (Note: This does not disable “searching”; it disables the “search indexer”)

Click on Start Menu > Computer > Right click on your SSD > Properties > Uncheck Allow files on this drive to have contents indexed in addition to file properties > Click OK.

Disabling Pagefile or Reducing Size:

Disabling Pagefile can benefit you (decreasing writes to the SSD) if there’s plenty of RAM running in your system. Since it’s basically used as virtual memory that’s stored on a section of your drive, it might not be a good idea to disable it if your computer has smaller amounts of RAM.

Click on Start Menu > Right-Click Computer > Properties > Advanced System Settings > Advanced Tab > Performance Settings > Advance Tab > Click Change under Virtual Memory > Uncheck Automatically manage paging file size for all drives > Click on No paging file > Click Set > OK > Restart your computer.

Additionally, if you have a secondary drive, you can assign Pagefile to that drive. If you decide disabling Pagefile may not be in your system’s best interest, you can reduce the file size that is written to your drive under custom size.

    I don’t have an OCZ SSD yet, but I’m glad I found this blog. Nice tips and tweaks. Thanks for sharing Junior!

    Okay now I’m confused – you recommend enabling AHCI, but in this doc:

    It says:

    > AHCI: the Advanced Host Controller Interface allows Hot-Plugging and Native Commands Queuing as well as multithreaded access of the drive by applications. Enabling AHCI results in conflicts between the controller and the drive that are apparent as sluggish overall system performance.

    So… AHCI or no AHCI??

    Also – I run Vertex2s in both Windows 7 and XP – it would be great to get specific Tips and Tweaks for XP! (And specifically – AHCI on XP? How to ensure Trim is enabled on XP?)
