Samsuang 840 Pro 256GB really slow help :(

How have you configure your SSD for example i do it like this 1. Ensure your SATA ports are configured to use AHCI mode in BIOS

This is the very first step to ensuring that you’re getting the most from your SSD. SSDs using AHCI (Advanced Host Controller Interface) SATA mode will perform much faster than SSDs in the old IDE (Integrated Drive Electronics) SATA mode, so this should definitely be the first thing you do when you after physically installing your new SSD. Unfortunately, there’s no universal way to do this, but be sure to check out your motherboard manual on how this is done. Do make sure to do this PRIOR to installing Windows!

If you’ve already missed this step, there’s a pretty easy way to do this in Windows.

Click Start
In the Search bar at the bottom type in “regedit”
Browse to “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci”
Right click on “Start”
Click Modify
Change the value data to “0″
Restart your computer
Go into your BIOS/UEFI and set your SATA Configuration to AHCI


2. If your SSD supports it, enable TRIM!

You may be asking yourself what is TRIM? Well, TRIM is a series of commands that are sent back and forth between the SSD and the rest of the computer that tells the SSD when files are no longer being used so that they can be deleted or cleaned up. These files are usually files like temporary internet files, so no need to worry about losing anything important!

To enable trim it’s pretty easy. Just a simple command through the command prompt (CMD), but first we want to test and see if it’s enabled. Click Start, in the search bar type “cmd” and right click your search result and click “Open as Administrator”. Once that box is open, type “fsutil behavior query DisableDeleteNotify” without the quotes. If you get DisableDeleteNotify = 0 then TRIM is working. If you get DisableDeleteNotify = 1 then we need to enable it.

To enable it simply type “fsutil behavior set disabledeletenotify 0″ without the quotes and restart your computer! It’s that simple. That said, most Windows 7 users will find that TRIM is automagically enabled, but just in case it’s not, be sure to do it!


3. Disable PageFile

I know some of you SSD experts are going to argue whether this is needed or not, but if you’re on a smaller SSD (60GB or less), I highly recommend it. Disabling the page file preserves a lot of free space on your SSD, which in the long term is better for SSD longevity. Do note that by doing this, everything will be cached to your RAM, so those with 4GB or less you may run into some low memory issues. Just make sure you’re not running 20 apps at a time to alleviate any issues.

To disable your PageFile:

Click Start
Right click ‘Computer’
Click ‘Properties’
Click ‘Advanced System Settings’
Click ‘Advanced’
Under Performance Click ‘Settings’
Click ‘Advanced’
Under Virtual Memory click ‘Change’
Untick ‘Automatically manage paging files for all drives’
Click ‘No Paging File’ and then ‘Set’

It’s that simple! Your Page File is now disabled!


4. Disable Superfetch and Prefetch

Superfetch and Prefetch, when running, simply tells Windows what it should expect to load next so it’s cached to your RAM. The nice thing about having an SSD of course is that you don’t really need to have things pre-cached into RAM. SSDs have ridiculous fast access times that are many, many, many times faster than traditional platter HDDs. Since, Superfetch and Prefetch is only going to eat up precious memory without giving you much of a benefit in the performance department, might as well disable them since you’ll probably need the extra memory after disabling the pagefile.

Click start, in the search bar type “regedit” right click your search result and click “Run as Administrator”
Navigate to this location “HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SessionManager\Memory Management\PrefetchParameters”
Right click EnableSuperfetch and EnablePrefetcher and modify their values to 0
Restart your computer
5. Disable indexing

When indexing is enabled, Windows is taking what it thinks is the most commonly used files and stores its file locations for quick access. While this isn’t taxing on your SSD, this does tax your processor. With SSDs being fast enough to access all files – commonly used and not at lightning speeds, there’s no reason to have indexing bog down your PC. Turn it off!

Click Start
Click ‘Computer’
Right click your SSD (usually C
Click ‘Properties”
Under the General tab look to the bottom and untick ‘Allow files on this drive to have contents indexed’


6. Disable System Restore

I know a lot of you rely on system restore in case anything terrible happens to your computer and it’s totally understandable if you don’t want to disable system restore. That said, the downfall to most SSDs is price and limited capacity. While disabling system restore won’t make SSDs any cheaper, it will free up a good chunk of space. Which… is good.

Click Start
Right click ‘Computer’
Click ‘Properties’
Click ‘System Protection’
Click ‘Configure’
Click ‘Turn off system protection’


7. Disable Hibernation

Similar to disabling system restore, disabling hibernation will allow you to free up tons of space as well. Plus, with your new SSD you can boot into Windows from a complete shutdown and open all your work back up again, just as fast as you can resume from a state of hibernation! That, or just use this other sleep mode called “standby”.

Click Start, in the search bar type “cmd”
Right click the search result and click “Run as Administrator”
Type “powercfg -h off”


8. Disable Write Caching

With mechanical hard drives, write caching is quite useful as hard drives frequently can’t keep up with the data that needed to be written on them, so data was stored onto memory first then transferred onto the hard drive. However, since SSDs are capable of extremely fast sequential and 4k writes, this is unnecessary.

Click Start
Right click ‘Computer’
Click ‘Properties’
Click ‘Device Manger’
Click ‘Disk Drives’
Right click your SSD
Click ‘Properties’
Click ‘Policies’ tab
Untick ‘Enable Write Caching for this drive’





Well, that’s it for now! It’s a pretty good list of optimization for those first time SSD users out there
